Superlift’s Replacement Radius Arm Lift Kits for 2005-2015 Ford Super Duty F-250/350 4WD Pickups have unique features that differentiates these kits from the others. These lifts hinge around a set of massive, high clearance, precision engineered, tubular radius arms designed to bolt right into the factory mounts. (We’re talking HUGE… in Form & Function).
The heavy duty radius arms utilize a press fit Clevite elastomer bushing to reduce Noise, Vibration and Harshness (NVH) at the chassis mount. At the axle mount, eccentric cam bolts (included) seat into an integrated eccentric cradle to achieve proper caster angles. The same radius arm works for the full range of lift heights… 4”- 8”. They also include a special ‘true flat’ jack plate surface.
All of these lift kits also contain new, engine specific rated coil springs. The track bar relocation bracket corrects the track bar geometry. The steering geometry is precise. (Yes, we did all the math for you.) All components used in these lift kits have been designed to work together to maintain the OEM alignment specification and to create the absolute best ride quality.
Available in 4 Inch, 6 Inch & 8 Inch Lift Heights, It’s a Super-EZ installation too.
