Lift Kit - 6 in. Lift - Coil Spring - Radius Arm - Bump Stop - 2.5 PES (2025 Ram)
Part number: BDS2135PESB
This BDS Suspension extended travel 6-inch Radius Arm Lift kit Designed specifically for Diesel-powered Ram 2500 trucks improves ride quality, handling, and off-road capability while maintaining excellent on-road comfort. With clearance for up to 37-inch tires, it delivers a more aggressive stance while preserving proper driveline geometry and everyday drivability.
Up front, the kit features Pro-Ride coil springs engineered to support the added weight of the Diesel platform while providing a smooth, controlled ride. Heavy-duty replacement radius arms play a critical role in the system by properly positioning the front axle and correcting caster angles lost when lifting the truck. By restoring proper suspension geometry, these radius arms improve straight-line stability, steering return-to-center, braking control, and overall ride quality, while their reinforced construction adds strength and durability for both on-road and off-road use. A Track bar relocaton bracket is included to properly center the front axle and maintain precise steering geometry. Also included is a brand-new 10-bolt transfer case indexing ring engineered to clock the transfer case for optimized driveline angles and increased suspension droop. This indexing ring features an all-new, industry-leading seal developed specifically for motorsports applications, delivering superior sealing performance, reduced friction, and long-term durability under extreme heat and speed. By properly clocking the transfer case, this system provides longer suspension travel and improved off-road capability compared to basic lift kits that do not re-index the transfer case. Additional components include sway bar links, brake line brackets, and premium shock absorbers matched to your selected configuration.
In the rear, lift is achieved using a pair of Pro-Ride BDS coil springs. Matching rear shocks are included to maintain balanced ride quality and consistent performance from front to rear.
- Extended travel shocks with transfer case indexing ring.
- Heavy duty tubular radius arms improve strength, handling and caster control
- Front high strength dual rate coil springs for a great ride on any terrain
