These rear 1″ lift springs match perfectly to our 2″ – 2.5″ front systems. They’re shot-peened & pre-set for longevity of the coil (it won’t ever sag), then powder coated to ensures the finish quality is as good as the spring’s performance.
This coil provides 1″ – 1.25″ of rear lift and runs 2 rates. The initial, softer rate is blocked out at ride height. This is NOT designed to be some super soft on-road rate – think of this as a “tender spring”. We wanted predictability in ride and handling so the truck will run on the 2nd rate unless the rear axle droops (offroad). Further, when loaded, it ensure sag is not exaggerated by initial collapsing of a softer rate. Take it in the dirt and, once the axle droops, the initial rate opens to keep the coil tight to its mounting perches while the extended travel shocks are pushed to the bottom of their longer stroke.
The “HD” Coils were designed with the intent that a Rebel WITHOUT the MFT or Rambox could carry 500lbs of constant cargo (Rack and RTT, tools, etc.) thus, it would only make sense that a Rebel with these options (equating to an additional 300+ lbs) would sit better with the extra spring rate.
These springs are designed for 2019+ new body style trucks. They do not fit old body style 2019+ trucks. If your truck is a 2019+ old body style, these are the springs you will need.

Customer Reviews
Added this HD coils to my ram because I have a heavy toolbox and is the best investment I could’ve done. Now I don’t feel the weight and rides so much better now
The customer service is incredible. The knowledge is outstanding great job.
Oscar was really helpful and very knowledgeable. Thank you.
So far so good. Small noticeable difference in ride quality but in a positive. Got rid of the rear end sag . I have a RSI smart cap, front runner rack on top of that with two roam cases and a decked storage with tools and a bunch of stuff inside plus a full size spare. That’s on my daily weigh. Once I go camping I add more stuff and weight and I did some heavy arithmetic and believe I have about 650 pounds of rear weight. Super fast shipping and extremely happy.
I installed fox 2.5 coilovers and needed some extra lift in the back. These springs added 1/2” in the rear. Rams are the best riding truck on the market today already however these springs along with the fox coilovers and shocks greatly improved the ride quality. I ended up calling CJC for support after my installation and their advice was spot on and fixed my issue.
Thanks Carli and CJC for creating and delivering an awesome product to finish my suspension modifications.
CJC Off-road made it simple to purchase and ship all my suspension parts to Canada without any issues. Thanks…
