Rancho 2005-2007 Ford SuperDuty 4x4 Radius Arm 4" Suspension Lift # RS6511B

July 2017 Update: This item has been discontinued by Rancho. It is out of stock and no longer available for purchase.

The Rancho RS6511B 4" Suspension Lift is designed for use on the Ford F250 SuperDuty and Ford F350 Super Duty pickup trucks. This Rancho suspension package starts with a competition style Radius Arm upgrade. The new heavy duty tubular-style Radius Arms bolt directly to the Ford F-250 and F-350 O.E mounting location without cutting or drilling. While adding superior strength and stability to the suspension, the new Rancho Radius Arms restore the caster angle to an optimal setting. Computer-calibrated, state-of-the-art coil springs (currently only available for Diesel options) improve both ride quality and performance. Steering integrity is uncompromised though the use of a new Forged Pitman Arm that ensures optimal steering geometry and eliminates bump steer. The Rancho Suspension RS6511B 4" Suspension Lift allows for the re-use of the stock Ford wheels and fits up to 35" or metric equivalent diameter tires! No cutting, welding, drivetrain or exhaust modifications are necessary, making this a complete bolt-on suspension lift system. Rear height is increased 2.5" inches using rear spacer blocks and longer U-bolts. Track bar relocation bracket, extended sway bar end links and brake lines round out an impressive list of easy-to-install features.
