This system offers a mild lift height with easy installation for clearance of 33" tall tires on K1500s. Lift is accomplished by utilizing the factory front Coilover shocks with steel spacer system that helps retain the stock ride of the front suspension.

The arms are constructed of top quality material including .120" wall 4130 Chromoly tubing with a 1.50" OD and 1" FK Stainless PTFE Uniballs. These arms are the best on the market for aggressive offroad driving in harsh conditions. The front differential is relocated to keep CV angles proper with the new lift height while a 1/4" thick steel skid plate provides protection against offroad obstacles.
