Rancho Long Arm Suspension Kit For 2007-2013 Jeep JK Wrangler

Tenneco’s Rancho® brand of performance suspension systems and shocks has announced the release of an all-new long-arm suspension system (Part no. RS66105B with black arms/springs; RS66105 with red arms/springs) for 2007-2013 Jeep Wrangler JK vehicles. The Rancho 4-in. long-arm suspension system includes a front adjustable track bar that provides axle center adjustment plus extended length, quick disconnect front and rear sway bar end links for increased articulation.

Each new Rancho long-arm kit includes front and rear coil springs, upgraded front and rear bump stop spacers and front and rear extended length brake lines to accommodate the increased axle travel. The new Rancho kit fits up to a 37-in. tire. No exhaust modifications are required when installing the new Rancho system on 2007-2011 Jeep Wrangler JKs. On 2012 and 2013 Jeep Wrangler JKs, the system requires the use of a Rancho cross-over exhaust pipe kit (RS72003) or a new front driveshaft. The Rancho cross-over exhaust pipe kit prevents contact between the cross-over pipe and the front driveshaft, allowing for optimal driveshaft clearance and more suspension down travel than exhaust spacers.
