The latest Rancho lift kits for Ford F-150 models have recently passed the U.S. Federal Motor Vehicle Safety Standard No. 126 – Electronic Stability Control Systems (FMVSS-126) test – and include a newly engineered one-piece, reinforced sub-frame composition and design for superior fit and finish.
A Ford F-150 outfitted with a 6-inch Rancho suspension kit (RS66501B) and Rancho RS5000X rear shocks (RS55287) and a Ford F-150 sporting a 4.5-inch Rancho suspension kit (RS66500B), Rancho RS5000X front struts, and RS5000X rear shocks were tested at the Arizona Proving Grounds, Wittmann, Ariz., by Link Engineering Company, Dearborn, Mich.
The trucks also included BFGoodrich Tires All-Terrain T/AKO2 35x12.50R18LT tires and 18-inch Vision Manx wheels finished in gloss black. Both Rancho Ford F-150 systems easily accommodate 35-inch tires and will not impact the Ford AdvanceTrac with RSC electronic stability control systems, according the manufacturer.
The new sub-frame is constructed from high-strength, low alloy steel and was engineered for high off-road performance. CNC-machined, durable extended length steering knuckles that maintain track width and ensure proper steering geometry are included in each kit. The 6-inch Rancho system also includes rear aft braces.
