2003-2018 Cummins Progressive Rear Add-a-Pack w/ 1" Lift (CS-DPAP-03-D)

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-DPAP-03-D

• For trucks wth 4" axle diameter
• Provides 1" of rear lift to match 3" front lift systems
  
• Improves predictability and keeps tires firmly planted
• Replaces the lower overload spring
• Includes u-bolts and centering pins necessary for installation

The 5 leaf progressive add a pack rear springs replace the lower overload leaf on the factory leaf spring pack (1″ thick leaf that doesn't follow the contour of the rest of the pack) with 5 thinner gauge leaf spring designed to maintain the factory load capacity while increasing mobility of the spring. Improved traction and predictability are immediately noticeable and as is a much-improved ride off-road and when loaded.

The 1″ lift provided by this pack matches to our 3″ front systems.
