Moab, Utah, March 31, 2012 –After launching six specific suspension systems suited to any type of Jeep owner, Rancho engineers designed several upgrade kits to provide the ultimate in flexibility and performance to the 2012 Jeep Wrangler JK.

The new upgrade kits – including an Upper Adjustable Control Arm Upgrade Kit and Sport System Upgrade Kit – give access to additional off-road capabilities when using a 2012Rancho Jeep Trail or Sport system.

“That’s what makes this new line of suspension systems and upgrade kits ideal for any type of Jeep owner,” said Mike Sype, engineer, Rancho. “They speak to the Jeep owner’s desire to modify and customize while adding performance benefits.”

Ideal for the Rancho 4-in. Trail system (RS66103/B) and 3-in. Trail system (RS66106/B), the new Rancho Upper Adjustable Control Arm Upgrade Kit(RS66151/B) allows the Jeep owner to utilize a pair of fully adjustable front and rear upper short arms, providing additional adjustability and off-road performance to the 2012 Jeep JK. Completely bolt-on, the short arms are constructed from high-strength, low-alloy steel and are available in either a black or red finish.

The new Rancho Sport System Upgrade Kit (RS66150/B), available for the Rancho Jeep Wrangler JK Sport systems (4-in. RS66102B; 3-in. RS66106B; and 2-in. RS66109BR9/RS66109BR5), provides for a more optimal angle for the driveshaft. The upgrade kit includes high-articulation front and rear lower short arms and adjustable front and rear upper short arms. The 100-percent bolt-on system also is contructed from high-strength, low-alloy steel. The kit is available in a red or black finish.

Both Rancho upgrade kits are compatible with 2WD and 4WD 2007-12 Jeep Wrangler JKs.
