Rancho Launches New Performance Suspension Systems for 2014 GMC Sierra 1500


The new Rancho 2014 GMC Sierra 1500 suspension systems recently passed the U.S. Federal Motor Vehicle Safety Standard No. 126 – Electronic Stability Control Systems (FMVSS-126) test – and were engineered to accommodate the varying steering knuckle materials being used by GMC.

The truck that recently passed FMVSS-126 included the new 6-in. Rancho suspension system, rear Rancho RS7000MT (RS7297) shocks, and front OE struts with spacers. The truck also was outfitted with BFGoodrich Mud-Terrain T/AKM2 325/60R20 tires and 20-in. Vision Off-Road Assassin wheels finished in matte black.

“We’re excited to announce that the new systems passed federal requirements for rollover safety,” said Chris Gauss, sales and marketing manager, performance brands, Tenneco. “The kits also exemplify our Rancho engineering heritage. We can accommodate either OE steel steering knuckles or OE aluminum steering knuckles through our system options, making it easy for Sierra owners to lift their new 2014 Sierra.”

The new systems include an entire host of components that help preserve performance while lifting the vehicle for extending off-road capabilities. The new systems feature a one-piece sub-frame for a precision-matched fit and added strength; high-clearance aft braces to maximize ground clearance; front differential drop brackets that correct pinion angle to help minimize driveline vibration; and extended-length, DOT-certified front brake lines.

The kits are available in two configurations to match the OE steering knuckle material, including Rancho engineered and fabricated extended steel knuckles (RS66301B) or aluminum knuckles (RS66302B).

The Rancho systems were designed for a fast, easy install – Rancho engineers maintained OE-quality steering precision by maintaining the factory’s rack and pinion location and preserved OE geometry for minimal bump steer. No drivetrain or exhaust modifications are necessary. The kits include highly detailed, illustrated instructions. All Rancho brackets are manufactured using high-strength, low-alloy steel.

Any of the Rancho performance shock absorber series (RS9000XL RS7000MT and RS5000) work with these systems.

The Rancho Sierra systems are backed by the Rancho brand’s limited lifetime warranty, see www.GoRancho.com for additional details.
