Carli add a packs for 2013-2018 Ram 3500 trucks maintain as much factory payload spec as possible (the only real reduction is the removal of the upper overload spring), but improve ride quality by replacing the lower portion of the factory leaf pack with a higher count of thinner springs. In doing so, ride quality over hard impacts or big dips is much less jarring. With the stock leaf packs, a hard impact would engage the overload springs and cause the rear end of the truck to buck.
These add a packs are the best solution for working trucks that still want improved ride. While the ride quality improvement isn't as dramatic as the full replacement Carli leaf springs, it's as good as it gets while keeping close to stock capacity!

Didn’t see many reviews on this so figured I’d take the opportunity. I have a regular cab long bed the goal was to get it back to level after a Thiren 2.25” front spring replacement was done. Front was about 1/2” higher than the rear from top of tire to the wheel well. Now it’s sitting as I expected, 1/2” higher in the rear. The ride, while still not Cadillac smooth, is drastically improved over the stock configuration. I would have gone full leaf packs but didn’t want to lose the payload capacity by doing so. I only have about 100 miles on it so I can’t really give a long term review but I’m confident it will work out well. Thanks for the quick shipping.
I just installed these on my 2018 Ram 3500 and found them to be fairly easy install for one person. Pros - nice ride
Cons - bad paint, rusted already, zinc coated ubolts instead of e-coat.
CJC was great!
Installed on a 2021 Ram 3500 with a Thuren kit utilizing the 2.75" (2.25" on 3500's) coils.
The add-a-leaf added about an inch of height to the rear and made the ride more controlled. This is a good option for those that don't want to lose payload from a full replacement leaf pack or have to add air bags to gain it back. It definitely still rides like a heavy duty leaf sprung truck but did smooth out the hard jounces and made the stance perfect when paired with the Thuren kit. I'm pleased with this purchase and overall ride quality has been greatly improved with these mods.
