  • Better weight handling than the stock rear coils.
  • Provide about 1/2" lift over stock height.**
  • Approximately 10% softer than stock spring rate while the axle is in droop, and about 20% stiffer that the OEM coils, when loaded down.
  • Each 5160 alloy spring is fully CNC computer formed and tested, using the most high-tech manufacturing processes.

Our Ram 1500 Dual-Rate rear coils were conceived, to help improve many aspects of the rear suspension. We were hoping to extract as much rear suspension travel out of the truck, while also increasing the main spring rate, to help the truck better deal with bed weight.

When the axle drops into a hole the spring rate is softer than stock allowing a longer spring, and this is how we get the extra suspension travel. With our Ram 1500 Dual-Rate coils installed you can now run the longest travel shocks that will bolt into the factory mounting.

** These coils are rather new, so we do not have accurate lift height measurements for all the different weights, or cab configurations. The 1/2" lift is referring to the most common Crew-Cab standard bed configuration.
