Our springs are specifically wound for off-road applications, not repackaged car springs. Our spring rates, wire diameters, and coil lengths have been developed through extensive real world testing on all types of terrain. Our race winning designs have been put to the test in the heat of battle from Baja to Dakar. All springs have closed and ground ends to sit flat and deflect true. We have the largest selection of springs to match your application. We sell thousands of springs a month with barely a return ever, yet we offer a lifetime warranty to the original purchaser against sagging and breakage. You will have the added peace of mind knowing you're covered, just in case. In the rare occurrence that a spring does fail, it will be cheerfully replaced with no questions asked.
