A 4" lift on the Power Wagon opens up 37" tires, meaningfully improves departure angle, and puts you in a different league for approach geometry on technical trails — but the rear air bag system is the variable that determines whether your kit install goes smoothly or sideways.
The Power Wagon's rear air spring suspension is the engineering detail that separates its lift kit category from almost every other truck. Most traditional 3/4-ton lift kits are designed for leaf spring rears — the Power Wagon uses air bags in combination with leaf springs, and a kit that ignores the air bag geometry will run the bags at the wrong travel range or bind them at full droop. Before purchasing any 4"+ lift kit for the Power Wagon, confirm that the manufacturer specifically designed the kit for the Power Wagon's air suspension, not the standard Ram 2500 with a leaf-spring rear.
BDS has a strong reputation for Ram 2500 work and their Power Wagon 4" kit ($2,299) is designed around the air bag rear — it relocates the mounting geometry to keep the air springs functional across the lifted travel range while adding new front coils, shocks, and a sway bar drop bracket. The ProComp 4" kit with Bilstein shocks ($2,699) is the upgrade if you want better shock quality out of the box. ReadyLift's 4.5" kit ($1,799) is the value leader — it's a capable kit at a lower price point, though the shocks in the base kit are adequate rather than excellent.
At 4" of lift, 37" tires fit without significant body trimming on most Power Wagon builds. The 6.4L HEMI has enough torque to pull 37s without a regear in everyday driving, though towing and high-frequency trail use will make the slightly lower effective ratio noticeable. The truck's 8,510 lb GVWR means you need load-rated tires at 37" — don't shop for tires by size alone without checking the load index.
