It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part # K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part # 126B2 to keep them lubricated. Nylon bushings, like part # SP05-060, are much quieter and can be used with regular bolts like part # 166081 since they don't need to be lubricated as much.

As far as lifespan goes the bronze will last longer but not so much longer that they are much better than the nylon style.

For the best of both worlds I recommend using Never Fail Bushings like part # LC279684. These are a bit more pricey but they are made so that they never wear out and they are self-lubricating which means you don't have to grease them. Lippert actually states to use regular bolts with these because grease can compromise the bushings and cause them to fail.

Hi Leo; I would start by checking to see if there are axle tags on the axles. They will probably have the capacity on them or at least a serial number the axle manufacturer could use to identify the axle. If the trailer manufacturer is still in…

Hey Henry, that's a great question but the answer is that it depends...it depends on if your axle is above the leaf spring or below it. If your axle is above the leaf spring it wouldn't affect the trailer height. If below it would raise it.…

Hey Richard! How did you measure your current leaf springs to get the 25-1/2" eye to eye measurement? We recommend jacking one side of the trailer up to get the weight off of them before measuring because they stretch out quite a bit over years…

Hey Mark, I looked up the specs of the spring you have now and found that it is a 24-3/4 inch long spring from eye center to eye center and for a 7k axle. So that means that the replacement spring part #EM28AJ that you referenced will work great as a…

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…

Answer 6

The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it…

In order to change from an 7,000 pound axle to an 8,000 pound axle you will need to replace the entire axle with an 8K model. You will not be able to add any parts to your current axle to upgrade it to an 8,000 pound capacity. We do not currently…

Hello Lyn; I can definitely point you in the right direction of a new shackle kit and leaf springs for your 2019 Grand Design Imagine 2500RL. The 2-1/4" long shackles are pretty common and for that I recommend the MORryde Suspension Upgrade Kit…

The tire and wheel combos we carry are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you really wanted to though. What some manufacturers will do is line up the light spot on the tire with the heavy…

Answer 10

Special trailer tires do not really need to be given a full dynamic balance like passenger vehicle tires do, but tires on a tow dolly probably should be balanced since just these two tires will have an effect the overall handling of the dolly. I…

Answer 11

All of the tire/wheel combos we sell are already balanced in the manner that trailer tires are balanced. Every tire and every wheel has a high (heavy) and low (light) spot. The manufacturers offset the high spot on the tire with the low spot on the…

Answer 12

There isn't a correct option for a slipper spring end type (radius or flat) for a 15k axle, or a particular fit for the Dexter Tandem-Axle Trailer Equalizer Kit for 3" Slipper Springs #HAP-203-03. Flat and radius ends are completely…
