The Gabriel FleetLine Cab Shocks are designed to eliminate cab vibration and offer the strength and durability needed to keep trucks running smoothly. The shocks are available in 1", 1-3/16", 1-3/8" and 1-5/8" bore sizes to address most cab suspension and designs. These shocks offer a gas-cell design that helps reduce fade from fluid aeration; a hydraulic stop that inhibits shocks from topping out and suspension from over-extending; chromed piston seal for consistent damping ability and reduced fade throughout the shock life; and 10-stage valving to help provide consistent control at all speeds and under all operating conditions.
