This unit delivers 9-position adjustable damping, letting drivers dial in their preferred ride character from trail-ready stiff to daily-driver comfort without removing the shock from the vehicle.\u003c\/p\u003e\u003ch4\u003eRancho RS9000XL 9-Position Adjustable Performance\u003c\/h4\u003e\u003cp\u003eRancho's RS9000XL platform uses a triple-tube design that separates the working, reserve, and outer tubes to maintain consistent fluid volume and pressure across the full range of suspension travel. The RS994310 is gas-charged and calibrated for the increased suspension geometry and additional weight loading produced by a 4-inch lift. Adjustments are made via the external adjuster knob at the top of the shock body: position 1 provides the softest, most compliant ride for highway cruising, while position 9 firms up damping for aggressive off-road driving or loaded towing. All nine settings are accessible in seconds without special tools.\u003c\/p\u003e\u003ch4\u003eBuilt for the Rancho RS6558B 4-Inch Lift System\u003c\/h4\u003e\u003cp\u003eThe RS994310 is not a direct stock-height replacement. It is purpose-built for installation alongside the Rancho RS6558B 4-inch rear lift kit. The shock's extended length of 26.63 inches and compressed length of 17.75 inches match the increased ride height and revised suspension geometry of that lift system. Running this unit on a stock-height H3 will produce incorrect suspension travel, potential frame contact, and unsafe handling. Always pair the RS994310 with the RS6558B lift as Rancho specifies.\u003c\/p\u003e\u003ch4\u003eConstruction and Hardware Details\u003c\/h4\u003e\u003cp\u003eThe RS994310 features a 2.750-inch diameter shock body machined from high-strength steel with a red polyurethane protective boot to shield the piston rod from trail debris, mud, and water intrusion. The upper mount uses a T-bar configuration and the lower mount uses a threaded eyelet, both supplied with polyurethane bushings that maintain precise alignment and reduce noise and vibration transfer into the chassis. All mounting hardware is included.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 x Rancho RS994310 RS9000XL rear shock absorber\u003c\/li\u003e\n\u003cli\u003ePolyurethane bushings (upper and lower)\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eRed protective boot\u003c\/li\u003e\n\u003cli\u003eRancho installation instruction sheet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\u003cp\u003eThe RS994310 fits the following vehicles when equipped with the Rancho RS6558B 4-inch rear lift system.
