BILSTEIN B8 8112 (ZoneControl® CR)

ZoneControl® CR: Position sensitive damping with 3 compression zones and 2 rebound zones, controlled by 3 independent pistons:

Compression (C): Provides superior bottom out control through a 2-stage, telescoping internal compression stop. This feature eliminates the need for an external hydraulic bump stop
Rebound (R): Secondary rebound stop will dissipate spring energy and stabilize the suspension directly following a large compression event. The internal rebound stop will also eliminate harsh top-out events and the need for an external limit strap

What is ZoneControl® CR?

ZoneControl® CR delivers position sensitive damping with 3 compression zones and 2 rebound zones, controlled by 3 independent pistons. Three key internal features produce ZoneControl® CR: JCO System, Triple Piston Design, RCO System.

Jounce Cut Off (JCO)

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.

Triple Piston Design

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 include: JCO (Jounce Cut Off) secondary compression valve piston, Main 60mm digressive piston, RCO (Rebound Cut Off) secondary rebound valve piston.

Rebound Cut Off (RCO)

The Rebound Cut Off (RCO) system is comprised of two components: the RCO secondary rebound valve piston and the internal rebound stop. The RCO system effectively decelerates the spring when the RCO secondary rebound valve piston engages the internal rebound stop.
