In 2007 GM went to a modified McPherson Strut front end, resulting in simplified manufacturing for GM and more lowering options for you! This kit changes the front coil spring on the strut and replaces rear springs with DJM lowered coils. Add a set of shock extenders to optimize the factory shocks, and you have a mild 2″ front and 2″ rear lowering kit that changes the ride height noticeably but doesn’t effect the ride. Definitely a DJM value! Keep your factory tires, wheels and shocks, no problem!
