2014-2025 Cummins Rear 1-2" Lift Multi-Rate Coil Springs (CS-DMRC-14-R1)

Note: There are differentiating factors between R1 & R2 Coil Springs. Review notes tab to ensure you select the proper option for your application

Not to be confused with Progressive Rate or Linear Rate Coil Springs, these Multi-Rate Springs are ideal for the daily driver or part-time off-roader. They provide a slightly softer, more compliant ride at low compression, and become firmer as more force is applied. This helps to dampen small bumps and vibrations; this variable spring rate prevents fatigue and sagging, effectively extending their lifespan.

IMPORTANT - R1 & R2 Coil Springs:

• R1: The perfect complement to an unloaded truck with custom-tuned Carli shocks. Ideal for customers desiring a level appearance and the BEST ride with capability up to 1,500lbs of bed-load.
• R2: Suited to the customer wanting to maintain the payload capacity and factory rake (unloaded), willing to accept a slightly firmer ride vs. the R1 (it is still softer than OEM rear springs). OR – The customer looking for the best ride and level appearance when loaded with a constant 800lbs (i.e., Overlanders).
