Superlift Releases NHTSA-Compliant Ford F-150 6-Inch Lift Kit

Electronic stability control (ESC), also known as traction control, is mandated by the National Highway Transportation Safety Administration (NHTSA) for all 2012-newer vehicles under 10,000 pounds GVWR. When a vehicle’s side-to-side wheel speed variations are too great based on steering wheel angle, ESC assumes that the vehicle is skidding. The ESC’s computer then applies brakes individually as necessary to restore traction and control.

Federal Motor Vehicle Safety Standard 126 (FMVSS 126) is a test that validates ESC functionality. It requires an evasive lane-change maneuver to be safely executed at highway speeds. Aftermarket components that potentially affect wheel speed must be compatible with the factory ESC. Inaccurate wheelspeed information affects ESC as well as ABS and other systems such as adaptive cruise control.

Traditionally, robotic steering and pontoons are used for the FMVSS 126 test. As an alternative to robotic testing, Superlift,, was part of a pilot project at Clemson University’s International Center for Automotive Research (CUICAR) to validate FMVSS 126 compliance using a computer simulator. Known as Hardware-in-the-Loop (HiL), a computer “runs” the lane-change test on an actual aftermarket-modified vehicle. The vehicle is stationary, but the ESC functions as if it’s actually doing the lane-change test. The HiL computer monitors the ESC readings and compares them to the factory parameters.

Using HiL testing, Superlift verified that its 2009-current F-150 4x4 6-inch lift system is compatible with Ford’s factory Roll Stability Control and Advance Trac ESC systems. Superlift isn’t aware of any other Ford lift kit on the market that has passed the FMVSS 126 test/has proven ESC compatibility. In addition to traction-control compliance, Superlift designed its current-model F-150 suspension system to be durable, affordable and installer friendly. The Superlift F-150 kit also includes all the necessary relocation brackets and parts for the brake lines, front swaybar and compression travel stops. All Superlift components are covered by a Limited Lifetime Warranty.

Maximum recommended tire size with this kit is 35x12.50. A minimum 20-inch diameter wheel is required, 8.5 to 9.5 inches wide, with backspacing between 4.0 and 5.5 inches. Installation requires cutting the OE frame. Superlift recommends that the job be done professionally. Estimated shop time is six to eight hours, not including alignment and headlight re-aiming.
