Great question, Brian!

The bushings that fit on the bolts for the shackle straps tend to wear out a bit faster than the ones that connect your leaf spring directly to a hanger which is why there are only 4 bushings in the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00.

If you wanted to get 2 additional of the bushings that come in this kit then the part # D014-077-00 is the exact same bushing so you just need to order 2 of them as well.

Yes, but the top bolt on the shackle side will not accept a bushing unless the hole in the frame mount is drilled out to 11/16" If you don't do this, the supplied "wet" bolt is useless.

Hello Mark, thanks for reaching out. When replacing leaf springs, it is important the new springs are identical in length to the old ones. There is a small amount of tolerance, like 1/2" or less, but any more than this can throw the suspension…

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…

Hey Thomas, the most important factors for picking out a replacement leaf spring for a trailer are matching axle capacity and length. Getting the same amount of leaves in the spring pack is actually not a huge priority so I wouldn't worry too…

Answer 4

There is no exact way to determine the leaf spring length. The best way to determine the length for a replacement is by measuring the existing leaf springs. The hanger distance and shackle length can help you get a good idea, but you're looking…

If you are wanting to go to higher capacity leaf springs I would advise against it. The problem is that since the trailer axle is rated for 3,500 pounds you won't gain any additional capacity by switching to higher capacity springs. What it will…

Answer 6

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

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…

Answer 8

Yes, you could use leaf springs for a 4,000 lb axle, like part #e57SR (rated for 2,000 lbs each), with a 3,500 lb axle but it will make your ride a bit more stiff. The only times that a leaf spring would become damaged is if it is overloaded or has a…

Answer 9

Yes the 4,000-lb leaf spring is compatible with a 3,500-lb axle. There are a couple of important measurements. Spacing from eye to eye on the spring when unloaded with no weight on the axle. Inner eye diameter of the spring roll Spring width from…

Answer 10

Dexter 4,000 lb axle leaf springs like the part #e48SR for 26 inches long or part #e57SR for 25-1/4 inch would work great with a 3,500 lb axle. There would be no issue with 1,700 lbs of weight either.

Answer 11

Trailer leaf springs can grow longer after many years of use. A new springs that measures 25-1/4-inches long like #e57SR could easily measure 25-1/2-inches after years in service on a trailer. Springs can lengthen as much as 3/4 of an inch. If your…

Answer 12

Thank you for the information. As long as the spring is of the correct weight rating and size, the number of leaves in a spring (spring pack thickness) isn't important. This is especially true because all springs should be replaced at the same…
