2 for 1 Special, Teraflex Jeep Gladiator JT Performance Spacer Leveling Kit and Daystar 3/4" rear spring spacers. Tera flex includes 4 spring spacers and 2 bump stop extensions. 1 pair of 1" spacers, 1 pair of 0.5" inch spacers. Choose between 1 inch or 1-1/2 inch front suspension lift/leveling by simply stacking the spacers. After installation, Sport and Mojave models can run 33" tall tires and Rubicon can run 35" tall tires. Teraflex is easy to install, gives you a rugged look and lets you install a bigger tire and wheel package. The Daystar 3/4" rear spring spacers install below the rear springs. By installing both you level out and don't squat when you load up or tow. Teraflex has a fantastic video on youtube regarding installation, plus plenty showing how to install the Daystar.
