Tenneco Inc.’s new Rancho performance 4-inch Crawler short-arm suspension kit is designed to add a competitive stance, drivability and performance to popular 2017-07 Jeep Wrangler JKs and Jeep Wrangler Unlimiteds (RS66114B).
“The Rancho short-arm Crawler kit adds ground clearance, high-articulation capabilities and a proven design that delivers during rock-crawling and technical driving,” says Chris Gauss, director, performance products, Tenneco. “We’re excited to bring this kit to market with these exciting new features, and it’s proof that we have an enthusiast-first approach.”
Each kit contains progressive rate front and rear coil springs; heavy-duty front and rear adjustable track bars; and new fully adjustable upper and fully adjustable extended length, heavy-duty Rancho control arms.
The company says carefully crafted and designed Rancho adjustable track bars are constructed from heavy-duty steel that adds strength during periods of heavy use. The Rancho control arms feature new Rancho D2 synthetic high articulation bushings to deliver superior dampening, improved ride/handling characteristics and no maintenance.
The kit also includes an extended length front sway bar end link; upgraded front and rear bump stop spacer; front extended length brake lines; rear brake line drop brackets; and rear sway bar spacers.
The kit allows for use of up to 37-inch tires and fully integrates with the vehicle’s factory stability controls. The new Rancho short-arm kit is compatible with any of Rancho’s performance shock series, including RS5000 Xs, RS7000 MTs and RS9000 XLs.
Completely bolt on, the new Rancho system includes highly detailed, full-color product installation guides. The kit also contains all necessary hardware and brackets. Rancho performance suspension systems are engineered and manufactured in the United States.
A Rancho exhaust crossover pipe (RS720003 for 2017-2012 models) is required when reusing the OE front driveshaft. The Rancho crossover pipe is sold seperately.
The Rancho Crawler short-arm kit is offered with a Rancho Limited Lifetime warranty. For more details, visit www.GoRancho.com.
