The Ram 2500 and 3500 are purpose-built workhorses — but that same heavy-duty construction means suspension upgrades require more thought. Get it right and you have a truck that tows 20,000+ lbs and rides like a performance vehicle. Get it wrong and you're fighting geometry issues and premature wear.
Lift Options for Ram 2500/3500
Leveling Kits (1-2.5 inch)
The most popular starting point. A leveling spacer corrects the factory rake, improves approach angle, and allows slightly larger tires. Works with factory suspension without major geometry changes. Perfect for trucks used primarily for towing that want a better stance and modest tire upgrade.
Full Lift Kits (2.5-6 inch)
For builders wanting 35-37+ inch tires and improved ground clearance. Carli Suspension makes some of the most respected Ram HD lift kits available — their systems are specifically engineered for the Cummins-powered 2500/3500, delivering exceptional on-road manners while maintaining serious off-road capability.
Shock Selection
- FOX 2.0 Performance Series — solid all-around shock for most Ram HD builds
- Carli Remote Reservoir Shocks — purpose-tuned for Ram HD, exceptional heat management for towing
- King Shocks (Carli-tuned) — the premium option, available through Carli curated packages
