Description
The ZoneControl R double-piston system makes rebound damping position-sensitive, with the stated purpose of preventing harsh top-out and eliminating an external limit strap. Independent click settings adjust low- and high-speed compression through Dual Speed Adjustment.
Size and application
The B8 8100 direct-fit range is intended for lifted trucks and SUVs, with a 60 mm bore/piston and 2.65-inch outside diameter. Application-tuned velocity-sensitive digressive valving and nitrogen monotube construction target consistent damping, comfort and control with reduced fade. Reservoir placement is remote or piggyback according to application.
This gray shock has stud/eyelet mounts, a reservoir and 14.65/22.99-inch compressed/extended lengths. Ride height is fixed; no boot or spring is supplied. Check the exact Ram 2500 configurations below.
Compatibility
Any mounting, position, size and component restrictions stated elsewhere in this listing still apply.
