Hello Steve, thanks for reaching out. In my honest opinion, leaf springs are leaf springs. There is not going to be a noticeable difference in quality or longevity between the different brands. As long as the length of the spring is correct and the…

Hello Eric, The #K2R35DKG is Dacromet-coated, and the calipers are treated with KodaGuard. The #K2R35DS, on the other hand, is made entirely of stainless steel, hence the higher price. If you're in an area where road salt is common or if…

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 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 Michael, the leaf spring part #e66SR that you referenced would not work for you as it was designed for a much lighter 2,500 lb axle. So instead you'd want a leaf spring that was designed for 7k axles like the part #TRU52FR which is similar in…

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…

Hi Brandon! For the Dexter 5-Leaf Slipper Spring w/ Flat End for 10,000-lb Trailer Axles - 30-1/2" Long #DX45QR, you will want the Bronze Spring Eye Bushing, 3/4" x 1" x 2-1/2" #14-67. This is a direct replacement for what came in…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…

Hello again Adam! Since you have 7k Lippert axles the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers #RM-2460-2570 is the correct kit. This is going to be a significant improvement over the stock suspension. For wet bolts you…
