This BDS Suspension extended travel 4-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 Gas 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.
FOX 2.0 Performance Series IFP shocks feature aluminum construction and internal floating piston technology for consistent, fade-free performance. FOX 2.5 Performance Series IFP shocks increase oil capacity and cooling for enhanced damping control in more aggressive terrain.
At the top level, FOX 2.5 Performance Elite Series shocks with Dual Speed Compression (DSC) adjusters deliver race-inspired performance and tunability, allowing independent adjustment of low- and high-speed compression for maximum control and versatility.
Built with BDS Suspension’s uncompromising commitment to strength, ride quality, and long-term reliability, this 4-inch radius arm lift kit is the ideal upgrade for Ram 2500 owners seeking improved handling, corrected suspension geometry, increased suspension travel, and confidence-inspiring performance both on and off the road.
