These Carli full length progressive spring packs are built by Deaver Spring Mfg specifically for Carli Suspension on the 2019+ Auto-Leveling Air Suspension Ram 3500 SRW/DRW. The standard spring pack was scrapped in favor of a MUCH higher capacity, but still full progressive, spring to ensure no undue stress was put on the factory air system. Massive weight capacity but smooth street ride designed for the Daily Driver and Weekend Warrior. Ideal for work and play.
