The Zone Nitro Stabilizer uses a pressurized nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving for lightning-fast dampening adaptive to whatever terrain you traverse on- or off-road. The 2-inch bodied shocks use a large 1-3/8-inch fluon-banded piston, self-lubricating seals and a 14mm hardened chrome shaft to help resist rock chips and corrosion.
