Daystars KC09112 Comfort Ride Suspension systems are truly Driven by Design. KC09112 Comfort Ride kits are specially designed to work with stock suspension components to keep costs down and quality high. High-density Progressive Polyurethane strut and spring spacers act as isolators to combine moderate amounts of lift without losing the comfortable ride you have come to expect. In torsion bar applications, re-indexed torsion keys allow you to dial-in the desired amount of lift in order to plus-size tire and wheel packages. These front lifts are often combined with Daystars Greaseable Super Shackles, add-a-leafs, or blocks and u-bolts to provide complete front and rear kits.
