Get the Ride You Want on the Street with the Setup You Need on the Track in One Convenient Kit
Progressive Coil-Over Kits showcase the latest in monotube shocks with application-specific valve technology. Displacing rod volume differently, these shocks have a patented poly "puck" to simulate the functions of a gas-charged shock; the result is more exact valve force control. Unique, double-wound, progressive rate springs are included, and they're appropriate for 85% of rear applications in motorsports. Simply adjust the spring platform to achieve the suggested 13-1/2" ride height. Two kits cover rear shock and spring combinations from 1,900 to 3,900 pounds to eliminate the hassle of spring rate trial and error.
