Bilstein B8 8112 Series 10-23 Toyota 4Runner Zone Control Monotube Front Left Corner Module

Never before has so much capability been packed into one direct fit suspension kit. BILSTEIN B8 8112 (ZoneControl® CR) suspension kits incorporate a new, revolutionary technology, delivering position sensitive damping in both compression and rebound. ZoneControl® CR provides unparalleled comfort during everyday driving conditions, combined with maximum control under large suspension inputs. The Jounce Cut Off (JCO) system is comprised of two components: the JCO secondary compression valve piston and the 2-stage telescoping compression stop. The JCO system provides bottom out control when the JCO secondary compression valve piston engages the 2-stage telescoping internal compression stop. This feature eliminates the need for an external hydraulic bump stop. ZoneControl® CR features a triple piston design for unparalleled comfort during every day driving conditions without sacrificing maximum control off-road. The 3 independent working pistons features: JCO (Jounce Cut Off) secondary compression valve piston, Main 60 Millimeter digressive piston, RCO (Rebound Cut Off) secondary rebound valve piston.
