TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview
Upgrade your stance and performance with the BDS 4" Radius Arm Suspension Lift Kit, engineered exclusively for 2025 RAM 2500's with diesel engines. This kit lifts the front 4" and rear 2.5", giving your truck a leveled, aggressive look with enhanced off-road capability and on-road comfort.
Built for durability and precision, it features heavy-duty BDS Radius Arms, a forged pitman arm, and your choice of high-performance shocks—BDS NX2, Fox 2.0, Fox 2.5, or Fox Performance Elite with DSC. Designed for standard travel, this system doesn't require a transfer case indexing ring or crossmember, simplifying installation.
Tested in North America’s harshest conditions, this kit delivers the strength you need and the ride quality you want—whether on the job, on the trail, or on the road.
Backed by the BDS No Fine Print Warranty—if you break it, BDS will replace it. No questions asked.
HD Radius Arms
In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.
Pro-Ride Coil Springs
A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
