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
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
|| L44649 (1-1/16″)

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 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 race 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.
| Hub Centric Wheels are centered by the center bore of the wheel and the hub flange.
|| Lug Centric wheels are centered by the torque of the lug bolts; rather than the hub flange.
There are two distinct types of wheels found on today’s Cars, Light Trucks, RV’s and Trailers. There are Hub Centric wheels and there are Lug Centric wheels.
The most common automotive wheels are Hub Centric in design. The center hole of these wheels is the actual center bore of the wheel. These wheels can be properly mounted and accurately balanced using the standard cone system supplied with most off car computer balancers.
Many of today’s RV & Trailer wheels are Lug Centric in design. The center hole of a Lug Centric wheel is not the true center. These wheels cannot be accurately balanced using the normal automotive cone wheel balancer mounting system in use by most repair shops.
Many Lug Centric wheels may appear to be mounted correctly with the center cone system, but they cannot be accurately balanced. The wheel balancer will continue to either “chase weights” or the wheel will show signs of imbalance when re-mounted on the RV or Trailer.
To ensure an accurate balance, Lug Centric wheels must be mounted on the balancer through their lug bolt pattern. Lug Centric wheels, when mounted on the RV or Trailer, are centered by the torque of the lug bolts and not the center bore of the wheel.
The only way to properly balance Lug Centric is through their lug bolt pattern. This style wheel must be mounted to the computer balancer in the same manner as it is mounted on the vehicle…through the lug bolt pattern.
Lug centric mounting on the wheel balancer mimics the way the wheel is mounted to the vehicle. If you are balancing Lug Centric wheels, you must use an Atlas Universal Adaptor ™ or similar devise. The standard cone system will not work properly.
Protecting your snowmobile trailer from wear and tear during heavy usages is just as important as protecting you Snowmobile. There are a few companies out there that make snowmobile trailer accessories designed to protect and secure. Two companies leading the charge in innovation and quality are Caliber Products and SuperClamp.
Caliber Products manufactures products focused on maintaining the trailer deck and ramp while making it easier to load and unload snowmobiles. Their products usually help aid in gripping or gliding depending on where the item is designed to be used. Glide products are designed to help the Skis’s slide on and off the deck without damaging the wood while the Grips are there to help the track grab the floor while protecting what is underneath. Grips and Glides both come in varying thickness, sizes and patterns so chances are the right combination can be found to fit any application.
SuperClamp’s products are designed to aid in the securing of snowmobiles on the trailer for transportation to and from the trails. Their products include tie downs that will secure the rear or front of any snowmobile. Front and Rear tie down systems are designed to be quick and easy to use without sacrificing strength. It is also possible to add a padlock to these systems to add further security if snowmobiles are stored on trailer or sometimes left unattended.
At the end of the day maintaining or protecting the trailer used to transport the snowmobiles is just as import as the snowmobiles them selves. The last thing anyone wants is to have to fix a broken trailer instead of hitting the trails.
It’s that time of year again to start thinking about winter activities and preparing for the season. One of the more popular winter activities is snowmobiling. Often not thought about until it’s too late, similar to boating, the trailer is a key supporting piece to the fun. If something brakes or malfunction’s on the trailer it has the potential for some pretty serious consequences. Luckily with our OEM parts, as well as aftermarket parts, you should be able to avoid preventable issues.
Along with the standard parts we have always carried; tires, wheels, axles, and so on, we now carry factory direct parts specifically for snowmobile trailers from Triton Trailers and Karavan Trailers. These parts include tilt bed hardware, coverall hardware, ski hold downs, and other hardware specifically found on snowmobile trailers. Some of these parts are small but important and may be worth having an extra in your tow box, such as a tilt bed pin.
We also carry everything that you would need to outfit your trailer to protect the longevity of the deck and ramp. We carry products from Caliber and SuperClamp that are designed to add traction and protection to the trailer. These products included deck slides, track grips, ramp/shields, and more that will greatly improve the ease of loading and unload snowmobiles.
Unique Functional Products, UFP as they are commonly known, offers two different series of disc brakes. They offer a DB-35 and a DB-42 and since the parts are not interchangeable it is essential to be able to identify what you have.
The DB-35 visually appears more similar to an automotive caliper. It will have two mounting ears below the body to attach the caliper directly to the axle brake flange. The rotor is also identifiable but it can be a little more difficult. On the rotor/hub there will be a minimum thickness of 17mm (MIN THK 17.0 MM) stamped on the inside of the back.
The DB-42 is visually unique and consists of a thick caliper body that houses the piston, and a metal shroud that will house the pads. The DB-42 will have only one mounting bolt hole located in the center of the bleeder valve and brake line port. On the rotor/hub there will be a minimum thickness of 22.40mm (MIN THK 22.40 MM) stamped on the backside.
