The ZR2 Front Leveling Kit with High-Angle Upper Control Arms increases front ride height by up to 1¼ inches, levels vehicle stance, and provides a greater approach angle, all of which help enable the use of popular off-road tire combinations. High-angle upper control arms maintain optimal joint articulation for increased front-suspension travel, and upgraded ball joints increase cross-car articulation by up to 18%. The sealed ball joint and boot design based on Chevrolet Performance standards provides a protected environment from off-road elements. This system provides additional integration with the DSSV Damper Spool Valves to maintain the factory ride quality of stock ZR2. Chevrolet Performance recommends use with: Ball Spline Half Shafts (84429060), Front Jounce Shock System (84403780), and Tie-Rod Sleeve System (84419134).
