RV Folding Steps

In an effort to continually offer new and useful Recreational Vehicle products to our customers, we would like to highlight the availability of Lippert RV & Camper Entry Steps. Our selection consists exclusively of the “Kwikee” and “Tread Lite” step series. They each offer their own unique features and are both designed to meet a variety of consumer demands.

Kwikee Steps

Lippert’s Kwikee steps are electrically powered and are actuated via a sturdy 12v DC motor with fully sealed electrical connections. The DC motor drives a solid steel rod that is encased in a durable stainless steel sleeve. To increase the quality and durability of their steps, Lippert constructs every Kwikee using air pressed rivets at all pivot points. With occasional greasing to the rivets you can ensure years of continuous use. Each Kwikee assembly features steps with built in grip surfaces that are garnished with high visibility reflective yellow strips. Kwikee steps are capable of supporting up to 750 pounds and are available in single, double and triple step assemblies. They are mounted by bolting directly to the frame of your RV or Travel Trailer via pre-drilled bolt holes.

Tread Lite

Tread Lite steps are Lippert’s top of the line Assembly. They are functional, lightweight, aesthetically pleasing and fully automated. The Tread Lite steps are actuated via a sturdy 12v DC motor and offer a number of additional features over the Kwikee series. Tread Lites have integrated LED lighting to provide better visibility as well as anti slip coated surfaces to ensure solid footing. They can also be synced to auto extend and retract with your RV’s door. As an added safety feature, the steps are able to detect obstructions in their path. The steps can also be extended indefinitely while camping by using the “hold cycle” switch. They are constructed with anodized aluminum and on average run 13lbs lighter than the average competitors equivalent assembly. They are also available in single, double and triple step assemblies and are capable of supporting up to 350 pounds. Tread Lite steps will have to be bolted directly the frame of your RV or travel Trailer using pre-drilled holes.

Replacing Trailer Fenders

Trailer Fenders

Fenders, while seemingly innocuous, are actually an essential part of your trailer. Fenders protect your boat and trailer as well as other vehicles on the road from debris. Fenders can also provide a stepping point for accessing both your boat and trailer. For these reasons and many more, it is important to maintain and care for your fenders and when the time comes, find a suitable replacement.

That being said, you may be wondering where to begin. The process we use to determine which replacement fender you need is based in large part around narrowing the search. As you will see below, this is done using basic observations and a few simple measurements.


Observations about your trailer  

  • Who manufactured your trailer?
    • If possible, identify who manufactured the trailer. This is a useful piece of information and can really help narrow your search. Your trailer’s registration or title are both good resources if the trailer’s markings are no longer there. If it is not possible to identify the brand you can still find your replacement fender without it.
  • What is your tire size?
    • While tire size can slim down the options, this is not the only factor used to determine your fenders size. Just because a fender has a description that calls for use on “x” sized tire, it does not mean that it cannot be used with other sized tires.
  • How many axles are on your trailer?
    • The number of axles on your trailer will help determine what fender you need and assist in narrowing the search.

Observations about the fender

  • What material is the fender made out of?
    • Generally speaking, most fenders are made out of one of three materials, plastic (available in black, white and grey) steel (galvanized or raw) and aluminum (diamond plate or smooth)
  • How does your fender bolt to it’s mounting bracket?
    • Plastic fenders typically bolt to the mounting bracket in one of two ways. Karavan style “Top Mount” or Standard style “Side Mount” (As shown in photos below).
    • If the fender is steel, take note of whether it is welded or bolted to the trailer.

Left: “Top Mount” Holes                        Right: “Side Mount” Holes

  • Does the fender have lights?
    • If the fenders have cut outs for marker lights, you will have to make a few observations.
      • How is the light fixed to the fender? Rectangular/round rubber grommet, etc (See photo below)
      • What color is the light?
      • Is the light LED or incandescent?
      • If it does have lights, you will have to know if the fender is on your left side (Driver’s/Road side) or Right side (Passenger’s/Curb Side)

Left: Circular Style                                      Right: Rectangular Style

  • What style is the fender?
    • Does the fender have rounded ends or “Jeep Style” square ends?

Left:  Standard Oval Radius                                 Right: Jeep Style

Measuring the fender

  • Overall length: Trailer fender overall length is measured by going from the farthest point of the fender to its parallel opposite.

  • Inside length: Fender inside length is typically taken when attempting to replace plastic fenders that have 1 or more steps incorporated into its design. It is measured between the inside mounting flanges of the fender (where it will bolt to the mounting bracket)

  • Width: Width is very simple, just measure from the back face to the front face of the fender at its widest.


  • Height: The easiest way to measure height is with the fender removed from the trailer. Simply place the fender on a flat surface and measure from the ground up.


Flexiride Torsion Axles

Our new Flexiride axles from the Universal Group provide one of the smoothest rides available for your trailer. Traditionally, trailer axles relied on the compression of leaf springs to allocate suspension support. Flexiride Torsion axles provide this needed support in a different way.  Using a hydraulic press, hardened steel shafts are pressed into into a solid rubber cartridge within the half axle tube. Torsion axles use the shear resistance of this steel rod within the stiff rubber cartridge to provide shock absorption. Torsion axles are able to provide better vibration dampening and shock absorption than their conventional leaf spring counterparts.

Flexiride axles are offered in a variety of weight capacities ranging 425 lbs to 7000lbs and in a variety of hub configurations. Several are available with bare spindles, idler hubs and electric or hydraulic drum brakes.

A unique feature of the Flexiride axles is that several are offered with an adjustable starting Angle. This attribute allows you to modify the ride height of your trailer. This makes their axles a more versatile replacement for traditional torsion axles that come with a fixed start angle.

Another versatile benefit of the Flexiride torsion axles is their two piece “half axle” design. At one time, replacing a torsion axle was a problematic process. Traditional torsion axle replacement demanded that the new axle be a perfect match in every way to the old one. Unlike leaf spring axles that have some fitment wiggle room, traditionally torsion axles came with pre-welded mounting brackets at a preset distance. Because of this, the axle’s mounting brackets were either a perfect match to mount to the trailer’s frame or it would be incompatible.

Flexiride axles are an excellent solution for a variety of trailer types as well.  For people with utility trailers, the ability to weld the axle where you need it makes versatile enough to work on anything from a toy hauler to a log splitter.

For boat guys with a deep V Hull, the ability to weld the axle to your trailer eliminates the need to find a torsion axle with a drop “v” center. For those not already aware, when loading a boat with a deep hull, the axle must be “v” shaped in the center accommodate loading and off loading. By offering the axle as two pieces, Flexiride axles are able to bypass this issue altogether.

Flexiride axles are mounted to a trailer in two different ways. Axles between 425lbs and 3500lbs have a separate weld on plate that once attached, will provide the bolt on mounting point for the axle. Flexirides that are 5200lbs and greater must be welded directly to the trailer.

LIONSHEAD Westlake Trailer Tires

Trailer Parts Superstore is now offering a line of Nitrogen filled tires from LionsHead. These new tire and wheel combos are offered with either Steel or Aluminum rims. They are also available with either Castle Rock or West Lake ST tires. While we have always stocked a large variety of trailer tires, these tires represent an innovative and new option in our selection. For those not familiar, using pure Nitrogen provides a longer lasting and more durable tire. Lastly, LionsHead’s industry leading warranty program provides customers with new found peace of mind, which you can’t put a price on.

West Lake and Castle Rock tires are both manufactured using highly durable nylon and steel chords as well as premium rubber. They are offered exclusively in a Radial tread as opposed to Bias-Ply. They are sturdy and have proven themselves resistant against the most unforgiving road conditions. Both tires are an excellent option for any trailer application and were purposely created to withstand the demanding nature of towing. With their unique tread design and Radial fabrication they are able to maintain the maximum traction between tire and road, their benefits are only enhanced when paired with Nitrogen.

In spite of the fact that Nitrogen tires are a relatively new concept for trailers, it has been used in the tires of everything from construction equipment to automobiles. Nitrogen use is beneficial for a number of reasons. Traditionally, air filled tires were prone to a buildup of internal moisture. This is because while air does contain Nitrogen, it is actually about 78% Nitrogen, 21% Oxygen, and 1% other but contains a variable amount of water vapor. This moisture can enable internal tire rot, inadvertently leading to premature failure.  Moisture buildup ceases to occur with Nitrogen.  Because of Nitrogen’s purity, it is inert, noncombustible and non-corrosive and it is unaffected by changes in external temperature. This means that Nitrogen filled tires maintain a more consistent PSI for a longer period of time. Tires filled with Nitrogen can also provide upwards of a 10% increase in fuel economy and have been shown to reduce tire failure by 75%. According to the NITROFILL™ website, estimates put the enhanced tire life as high as 50%.

These tires carry a duel warranty from both LionsHead as well as NITROFILL™. LionsHead’s warranty provides coverage against manufacturer’s defects and any claims can be placed with them directly by providing specifications as well as photos of your tires damage. NITROFILL™ offers a comprehensive warranty that covers everything from replacement tires to towing as well as numerous other added benefits. Simply register your tires with NITROFILL upon purchase to take advantage of these benefits.

Replacing UFP Bearings and Seals

UFP (Unique Functional Products) is a popular manufacturer of axle and brake components for the marine trailer industry. UFP was recently acquired by the Dexter Axle Company, who has taken over their parts manufacturing. Just as the name implies, UFP parts are VERY unique. When compared to industry standards, their parts tend to be proprietary. Customers frequently contact us in need of assistance in replacing various UFP components. The intention of this blog is to clear up confusion when replacing UFP parts, and make things a little easier.

You will need calipers (Digital or Analog). A tape measure will not be sufficient in determining these diameters.
UFP hubs come in several configurations, different carrying capacities, and in both grease and oil bath style. Determine the bearing configurations first.

We can accomplish this in three different ways:
1) Measure the old Bearings:
After removing the bearings, measure the inside diameter of the bearings with your calipers. The most common sizes with UFP are the following.:
1.06 (1-1/16”), 1.38 (1-3/8”), 1.25 (1-1/4”) and 1.75 (1-3/4”).

2) Measure the spindle itself:
After removing the hub, using our calipers, measure the front bearing and rear bearing surfaces. Don’t be concerned if your spindle doesn’t appear the same as the sample photo below — these measurements will determine everything we must know.
If the bearing surface measures between 1.058 and 1.061, you have a 1-1/16” bearing.
If the bearing surface measures between 1.36 and 1.39, you have a 1-3/8” bearing.

3) Find the reference number:
The bearing reference numbers are stamped into your bearings. Below is a cross reference table of various bearing sizes:

Bearing Reference Number Bearing Inside Diameter Bearing Inside Diameter
L44649 1-1/16″ 1.06
L68149 1-3/8″ 1.38
14125 1-1/4″ 1.25
25580 1-3/4″ 1.75

So now that we’ve made it this far, there’s another unique UFP topic to discuss. UFP uses a race smaller than industry standard with their 1-3/8” bearing. Using calipers, measure the outside diameter of the race. The Industry Standard size is 2.56. The UFP standard size is 2.328. If you’ve attempted to install a race and just can’t get it to fit, this may be why.

Just like bearings, the stamped reference numbers in the races determine their size. See the reference chart below for clarification.
Race Reference Number Race Outside Diameter Corresponding Bearing

Race Reference Number  Race Outside Diameter Corresponding Bearing
 L44610 1.98  L44649 (1-1/16″)
 L68111 2.56 L68149 (1-3/8″)
 L68110* 2.328 L68149 (1-3/8″)

*Denotes UFP smaller than standard

Replacing your seal
The final hurdle to overcome is replacing your grease/oil seal. There are two ways to accomplish this.1) Measure the old seal After removing the seal from the hub, you’ll use calipers for two measurements: the Inside Diameter and the Outside Diameter:2) Measure the spindle and hub:
Oftentimes when you need to replace your seals, it’s after a mechanical failure on the road. These events are often unforgiving on the old seal and bearings, and measurements from the seal are just not a possibility. In order to determine the Inside Diameter of the seal, measure the diameter of the spindle’s seal surface as seen in the diagram below:
To determine the Outside Diameter of the seal, we will measure the Inside Diameter of the hub itself:So you made it this far, congratulations! You can also apply these methods to replace UFP Torsion arms and Rotors. As always, if you need further clarification or just want to talk about this with one of our technicians, we can be reached at 1-800-453-7379.

Race Ramps!!

TrailerRamps_HOwToRace Ramps trailer ramps make loading and unloading low profile vehicles and equipment a stress free task. The end of the ramp is notched to seat your trailer ramp easily and securely. The added distance the Race Ramps provide allow for an incredible decrease in the approach angle for what is being loaded. This is perfect for any car show enthusiast that has a lowered or exotic car that they haul and worries about damaging the front or “bottoming out” when taking the vehicle on and off the trailer.

In the past many people used either a cut 2×4 or 2×6 to prevent scrapping during loading and unloading. The problem with wood is that it can age and weaken over time. The wood you get at a store also doesn’t have a weight rating which forces you to guess what would be appropriate for your need. With 7112005_xl2race ramps the composite material is both lightweight and strong so it will greatly outlast the life of a wooden board. Each Race Ramp will also have a weight rating giving you the confidence that it will never fail while loading and unloading. Unlike the wood alternative Race Ramps have a no-skid bottom so you never have to worry about sliding or shifting while loading and unloading.
