Description

Designed and built in conjunction with Deaver Spring MFG, these Carli Add-A-Pack Leaf Springs eliminate the use of your lower overload leaf, giving you thinner gauge leaves that improve mobility of the springs, traction, predictability, and ride quality off-road and when you're hauling without compromising load capacity.

Part Number: CS-FPAP-11

Features
  • Compatible with 3.5" axle tube
  • Progressive design addresses the harsh rebound of the factory overload spring
  • Includes U-bolts and hardware
  • Provides 2" of lift
  • Load capacity is maintained, and ride quality is improved
Notes
  • When it comes to the F350, the main spring pack in the rear is already quite stiff and does not compress much unless under load. As a result, installing the Add-A-Pack on an F350 may actually make the rear suspension stiffer, potentially even stiffer than the stock setup. For this reason, the Progressive Add-A-Pack is not recommended for an F350. To achieve optimal ride quality, we highly recommend installing Carli Full Replacement Leaf Spring Packs

Works great on my 2018 Honda Civic EX
Size: 2.0L, Size: 2.0L
Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!

Perfect
Size: 2.0L
I bought this and was able to change this myself. It was simple. I got this for my 2016 Honda Civic, I don't think I ever replaced the filter in my car in the 5 years that I had it. It had a distinct smell in my car, and once I popped this bad boy in, within a day or two the smell was gone. It did make a sound for a while like I did not do it correctly, but I did, after about a week the sound went away, so everything's good. I will buy this again when the time comes
