Hey Robert, A bouncy ride could indicate that your leaf springs are worn out and in need of replacement, but could also indicate that you're overinflating the tires. I would first check the tires to make sure the psi rating is the same as…

I never recommend using grease with Nylon Bushings #TRBU11566. The grease can trap dirt which will cause the nylon to become damaged easier. And the chemicals in different greases can cause the nylon bushings to break down. If you want to use Grease…

The equalizers that come with the Dexter Heavy-Duty Suspension Kit #K71-448-00 have bolt holes that measure 6" apart on center and then 4" tall on center as you can see in the attached photo. You'll want to measure your current…

In order to find the correct replacement leaf spring for a trailer you first need to start by noting the type whether that be slipper or double eye. Then, you'll need to measure their unloaded length via jacking up the trailer. If the springs are…

Dexter doesn't actually make a 4k rated axle, but they do make a 4.4k axle which has a diameter of 3 inches. The next smaller axle is a 3,500 lb axle which has a 2-3/8 inch outer diameter.
