JKS Manufacturing 4" Lift Coil Springs (1997-2006 Wrangler) - JSPEC3400
Dual Rate Design
Includes Front/Rear Springs
Designed for on-road comfort &
off-road performance
Increase clearance, performance and ride quality with a set of JKS JSPEC™ 4" lift dual rate coil springs. Fits Jeep Wrangler TJ and LJ models. Includes a complete set of matching front and rear coil springs for a level 2 lift. Dual rate springs provide smooth comfortable ride on road, and transition to a firmer rate when tire movement increases off-road for increased vehicle control. Another benefit is the longer overall length, which allows the use of longer shocks for more wheel travel. Whether loaded down with gear for a weeklong expedition, running light for some rock-crawling fun or loaded with a few friends for a trip to the beach, JSPEC™ coils provide the ride you want and the performance you need.
Since 1989, JKS Manufacturing has developed some of the world?s most widely used and respected products for Jeep vehicles. It all started when we pioneered the original Quick Disconnect brand of quick-release sway bar disconnects. Since then our product range has expanded to include such favorites as the ACOS line of height-adjustable coil spring spacers, and perhaps our most advanced creation to date, J-Spec Suspension systems including the JK Front Coilover Conversion.
