The ZR2 Front Leveling Kit with High-Angle Upper Control Arms increases front ride height by up to 1 ¼ 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.
