Whats the first thing the majority of Jeep owners do after purchasing their Jeep? Adding a lift and bigger tires, of course! Probably the most critical component of a lift kit are the coil springs. Sure, some systems use spacer blocks on top of the stock coil springs, others use a generic coil spring that achieves lift height, but doesn't improve the on and offroad handling of the vehicle. Its quite surprising what an impact a spiral piece of wire can make in how your Jeep gets down the road or trail, but it really does make for a difference. The folks at Rock Krawler are experts in their craft and know how to properly build a set of coil springs that will deliver superb performance in the dirt or on the pavement. These particular coil springs are specifically designed for the weight of the EcoDiesel engine and come in a variety of two different lift heights. Whether you're building your lift kit from scratch, or maybe seeking a better ride compared to the existing aftermarket coil springs, you won't be disappointed!
