Replacement Leaf Springs for 7000-lbs Axle

Question

Question:

I’m replacing the 7000# leaf springs on my Dual axel camper. The springs that you supply are 3/8” shorter than the junk Dexter put on. Will I be ok?

In most cases after use, leaf springs are going to flatten out, so when people go to measure them they're often slightly off from the measurements of the new ones; you'll want to make sure that the measurements are close, but matching the capacity is more important.

For your 7000-lbs axle you'll want to use the # e64SR, which are 24-7/8" long. These springs are 1-3/4" wide and as long as your old springs are within about 1/2" of those, you'll be just fine.

If your measurement is significantly different from that, please let me know and I can help you find the correct springs.

Answer 5

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…

Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily.…

Hey Patrick, so for your leaf spring upgrade I am going to need to know a couple of things before I can get you over to the right part. Specifically, the length from eye to eye, the spring width, leaf thickness, and the number of leaves. From here I…

Since Grand Design is kind enough to list certain parts for their trailers I can confirm you have a 33" wheelbase on your 2020 Grand Design Transcend 27BHS. This means the MORryde Rubber Equalizers #MR87ZR will fit your trailer. Although I'm…

Answer 10

Hey Todd, The 500lb increase in capacity to the 4-Leaf Double-Eye Spring #e22YR will definitely work and would probably give you a bit sturdier of a ride because the springs won't compress as easily. Going too stiff can cause problems though so…
