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…

Hey Jason, so we know that your 2020 Grand Design Solitude 390RK does have 8k axles so in terms of capacity the leaf spring part #e89FV that you referenced would work but we don't have a way to verify the length of your current springs so…

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…

Hello Brian; the 3/8" difference isn't enough to matter so you can use the #e89FV as a replacement. We do have the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb Round Trailer Axles #APUBR-8 for 3" diameter axles. This has 7" long…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

I can help you determine the right replacement double-eye leaf springs for your Keystone Hideout, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as all you need to do is measure your current leaf…

For a replacement leaf spring you need to know your axle capacity as well as the length of your current leaf springs. You will need to measure from center of one eye to center of other eye on your leaf spring that isn't broken. Since these are…

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.

You are indeed right to think this way. When picking out the appropriate leaf springs for your custom built trailer you will want to choose them based on what the actual loaded weight of the trailer will be. Just make sure that the leaf springs have…

Definitely looks like the springs are being overloaded and need to be replaced. You can use higher rated leaf springs but, the higher you go the stiffer the ride will be. Since we know the weight class with your axles the next step would be to…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…
