Following hot-on-the-heels of our recent 1622H 2013-up Ram 3500 3" kit, this new radius arm systems looks to put similar levels of performance in the 2011-16 F250s. Like the Ram kits, this new system is built around massive tubular replacement radius arms. These arms are built to handle far more than the factory parts they are replacing. The design incorporates a factory style rubber bushing mount at the frame to keep the NVH levels in check. The 3-1/4" diameter bushings are huge and have a long, maintenance-free service life. The new radius arms mount right into the factory locations so installation is simple and clean. Alignment cam locks are included that allow for caster adjustability, something the factory arms do not provide. The arm geometry is set to keep the axle angle in the factory specs while compensating for the 2.5" of lift. A copper-anodized aluminum BDS name plate is mounted each arm.
In addition to the heavy-duty, high-performance radius arms, this new system features dual-rate front coil springs that improve the ride and handling of these 3/4 ton trucks both on and off road. Our popular heavy-duty turnbuckle style adjustable track bar is included to center the axle. Front brake line relocation brackets included and a choice of NX² series or FOX 2.0 Performance Series shocks are available.
The rear system utilizes a 4" block with an integrated bump stop wing to replace the factory 2" blocks, leveling out the back with the newly lifted front
