JKS Manufacturing 97-06 Jeep Wrangler TJ 4in Coil Spring Box Kit

The dual rate design of these JKS JSPEC™ 4-inch lift coil springs is a key feature for your 1997-2006 Jeep Wrangler TJ or LJ. This unique spring setup starts with a softer rate for a comfortable ride on the road, making your daily driving or long trips more enjoyable. When you head off-road and encounter more significant suspension travel, the springs transition to a firmer rate. This change helps maintain better vehicle control when you need it most, whether you're navigating trails or carrying extra gear for an expedition.

Beyond just ride quality, these springs are longer than stock. This increased length allows for the fitment of longer shocks, which in turn provides more wheel travel. This means your Jeep can handle rougher terrain with greater ease and maintain better contact with the ground. The kit includes a complete set of matching front and rear springs, ensuring your Jeep sits level with its new 4-inch lift.
