Placing Boat Bunks for Maximum Contact with Boat with a Ribbed Hull  

Roller bunks like the Dutton-Lainson 5 Foot Long #DL21755 that you're looking at are designed to be installed on a boat trailer but there's no particular reason they couldn't also be used to make a ramp. We have indeed had…

The Wesbar Submersible Low Profile Trailer Light, #403026, uses bolts that require a 1/4 inch diameter hole to mount. The distance between the mounting holes is 4 inches on center and the bolts are 1 inch long.

The older generations of the Wesbar submersible low-profile lights came with sealed light bulb capsules that are not replaceable. If your capsule is sealed, then your best option is to replace the lights with new lights like part #403026 and…

The CE Smith Carpeted Bunk Boards like part #CE27845 are not treated. The marine grade carpet will do a great job of keeping out water so treatment is not needed. That said, if you would like to purchase your own treated lumber and wrap them…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside…

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material. For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs. For a 15 inch steel wheel with 1/2 inch wheel studs…

To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose #8-258-5UC1. If the inner bearings are marked…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

Hey there Zack, appreciate that info, and we do not offer an axle of that length, and they can be pretty tricky to find. Sometimes people will have to get their axles custom-fabricated at a local fabricator, but I do have an option to consider, which…
