Tenneco's Rancho Jeep Wrangler JL Suspension System Passes Federal Rollover Safety Test

Aug. 20, 2018

Tenneco Inc.’s latest Rancho brand performance suspension system for the 2018 Jeep Wrangler JL recently met the requirements of the U.S. Federal Motor Vehicle Safety Standard No. 126 – Electronic Stability Control Systems (FMVSS-126) test.

“Rancho continues to certify new suspension platforms to the FMVSS-126 protocol and the latest Jeep JL platform was no exception,” says Chris Gauss, director, performance products, for Tenneco.

The vehicle tested was a 2018 Jeep Wrangler JL that utilized a Rancho 4.5-inch crawler short arm system (Part No. RS66125B), RS5000X shock absorbers, BFGoodrich All-Terrain T/AKO2 37/12.50/17 tires and Vision Nemesis 17-in. wheels.

The Jeep JL testing took place at Arizona Proving Grounds in Wittman, Ariz., and completed by Link Engineering Co. of Dearborn.

The Rancho product line includes multiple suspension systems for 2018 Jeep Wrangler JL models. Tenneco says each Rancho JL suspension kit features a pair of front and rear corner-specific, heavy-duty progressive rate coil springs that are tuned to enhance on-road comfort for occupants and offer superior off-road performance.

Rancho has designed both RS5000X and RS9000XL shock absorbers to include the brand’s new Dynamic Rebound Spring (DRS) technology. Exclusive to the Wrangler JL system, Rancho DRS technology includes a unique internal system design that has a precisely tuned metal spring and fortified interior construction to improve control, reduce vehicle body roll and prevent rod overextension.

Rancho is headquartered in Long Beach, Calif., and is manufactured and marketed by Tenneco. Tenneco is the global supplier and manufacturer of the Rancho brand of suspension systems and components, shock absorbers, off-road protective equipment, specialty exhaust pipe kits and more for a variety of trucks, sport utility vehicles and Jeeps found around the globe.
