Firestone Ride-Rite 2013+ Ram ProMaster 1500/2500 (Ex. City Model) Rear Helper Spring Kit
The Firestone Ride-Rite 2648 Rear Helper Spring Kit is a heavy-duty air spring suspension upgrade for 2013+ Ram ProMaster 1500 and 2500 models (excluding City models). This adjustable air helper spring system mounts between the frame and rear axle to eliminate sag, improve ride quality, and restore load-carrying capacity when towing trailers, carrying heavy cargo, or operating fully loaded. Air springs inflate from 5-100 PSI to provide up to 5,000 lbs of leveling capacity per set, offering on-the-fly adjustability for varying loads. The kit includes durable air springs, brackets, hardware, air line, and inflation valves for easy installation. Ideal for fleet operators, delivery vans, camper conversions, or tradesmen who need reliable rear suspension support without permanent stiffening of the ride.
