Rancho’s latest performance 4-inch Crawler long-arm suspension system for Jeep Wrangler JKs brings premium construction and engineering enhancements to this popular off-road vehicle.
The new kit adds to Rancho’s already extensive Jeep product offering, which has played an integral role in shaping aftermarket suspension systems for Jeeps since 1955.
The new Rancho 4-inch Crawler long-arm kit (RS66115B) includes front and rear progressive rate coil springs and fully adjustable extended length, heavy duty Rancho control arms. The Rancho control arms feature new Rancho D2 synthetic high articulation bushings to deliver superior dampening, improved ride/handling characteristics and no maintenance. The new D2 bushings include PTFE to allow for free rotation of the bushing in the sleeve without resistance to help reduce wear and improve performance. The new Crawler long-arm suspension system fits 2017-07 Jeep Wrangler JK and Jeep Wrangler Unlimited 4WD models.
“The latest Rancho Crawler long-arm system for Jeep JKs is a direct result of our engineering team striving for continuous improvement, working with enthusiasts in the field, and developing one of the most unique, high-articulation on- and off-road suspension systems available,” said Chris Gauss, Director, Performance Products, Tenneco. “The new design offers the ultimate combination of a high-articulation off-road suspension system with a ride profile suitable for on-road, daily driver use for Jeep enthusiasts.”
