JSPEC 3" Suspension Systems for Jeep TJ

JKS launches 3" Jspec Suspension Systems for Jeep TJ

Coldwater, MI - At JKS Manufacturing, the core goal has been to develop products to improve the performance and capability of Jeep vehicles. From swaybar disconnects and adjustable track bars to complete suspension systems, JKS continues to be one of the world?s most widely used and respected aftermarket Jeep products on the market today. The newest addition to their Jspec suspension lineup are complete 3" systems for the 1997-2006 Jeep Wrangler TJ. These new systems join the existing TJ 2" system offering all the benefits of improved off-road capability and on-road drivability.

This system is built to perform. 3" dual rate coil springs are supplied for all 4 corners to not only to improve the ride quality and suspension travel, but increase load carrying capacity for those long adventures. These springs are paired with the Jspec gas charged shocks to offer comfort and performance across rough terrain both urban and natural. Front J-Flex adjustable lower control arms are supplied in the system to reposition the front axles and correct caster along with rear upper control arms to improve pinion angle. These control arms are built from heavy wall DOM tubing with an OE style rubber bushing and an adjustable forged flex end. To reposition the front axle laterally, an adjustable front track bar is supplied and bolts in place of the stock bar. In the rear the axle is repositioned with a heavy duty track bar bracket. JKS quicker disconnects are included to quickly and easily improve the front end articulation and longer rear sway bar links allow the rear sway bar to function in the correct position. To keep the driveline angle at a minimum the belly skid plate is repositioned down using the supplied lowering spacers, the transfer case linkage is relocated and the motor mounts are shimmed. Bump stop extensions and brake line brackets round out this system ensuring improved ride quality and performance on and off-road with room for 33" tires.

Improve your Jeep Wrangler TJ's ride quality and offroad capability with JKS Manufacturing and the 3" Jspec Suspension System. For more information head to the JKS Mfg website or call (517) 278-1226.
