DIESEL ONLY | BDS Radius Arm Coilover Lift Kits for Super Duty

Built for next level performance these coilover conversion systems offer improved all around performance, capability and comfort. At the heart of these kits are a pair of heavy duty replacement radius arms built to withstand whatever abuse you can throw at them. Constructed from 1-3/4" OD -10GA DOM tubing with support gussets, these radius arms are far superior to the factory stamped steel units. They use a high clearance design for extra ground clearance and and additional clearance of oversized tires. They incorporate factory style 3-1/4" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and utilize a lower cam slot to be used with the provided cam locks to correctly position the fron axle and correct caster angle.

This system takes performance to the next level with FOX 2.5 Factory Series remote reservoir coilovers with DSC (dual speed compression). These bolt into place using the supplied mounting brackets and pair with a set of FOX 2.0 performance series gas shocks. To improve steering angles a forged drop pitman arm is supplied with an integrated drag link flip. Used in combination with the 1/4" thick heavy duty track bar drop bracket will position the front axle and keep the track bar angle in phase with the steering for improved handling. Also included for the front suspension are a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets and a steering stabilizer mounting bracket.

In the rear, BDS supplies either a lift block and longer u-bolts to level the stance or replacement GlideRide leaf springs with integrated overload leaf for great all around capabilty and limit any potential axle wrap. Also included are rear u-bolts, rear brake line relocation bracket and FOX 2.0 performance series gas shocks. As with all kits these include all hardware and step-by-step instructions to complete the install.
