19-23 RAM 3500 ADD-A-PACK & BILLET BLOCK, DIESEL

The 5-leaf progressive Add-A-Pack rear springs replace the lower overload leaf on the factory spring pack with five thinner, carefully engineered leaves. This design maintains the factory load capacity while improving spring mobility, resulting in better traction, predictability, and a smoother off-road ride, even when the truck is loaded.

The 2019 Ram 3500 features an upgraded AAM 12″ rear axle (4.25″ axle tube) and a factory-lowered rear end, giving a 1″–1.5″ rear-high stance. To accommodate this change, Carli’s Add-A-Pack includes a 1″ machined billet aluminum block, delivering a level stance when paired with our 3″ front lift coil springs. Combined, the Add-A-Pack and block provide 2″–2.5″ of total rear lift.
