The RS9000XL series sits at the top of Rancho's performance shock lineup, purpose-built for trucks, SUVs, and Jeeps that tow, haul, or see regular off-road use. All Rancho RS9000XL shocks are manufactured to OE-equivalent fitment standards with upgraded performance materials and adjustability not available in factory equipment.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cstrong\u003eWhat does universal mean for the RHORS994012 RS9000XL shock?\u003c\/strong\u003e\n\u003cp\u003eUniversal means the RS994012 is not pre-fitted for a specific vehicle make, model, or year. It is intended for custom suspension builds, off-road fabrication, or specialized replacement applications where the builder selects the shock based on extended and compressed length measurements rather than a vehicle application lookup. Always measure your required shock travel and mounting dimensions before ordering a universal shock.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the 9-position adjustment work on the RS9000XL?\u003c\/strong\u003e\n\u003cp\u003eAn external adjustment knob is located at the top of the shock body. Rotating the knob selects one of nine damping positions, ranging from soft (position 1) for maximum comfort on smooth roads or light off-road terrain, to firm (position 9) for aggressive off-road use, towing, or high-speed trail driving. Position changes can be made while the vehicle is parked without any tools.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the RS9000XL nitrogen gas charged?\u003c\/strong\u003e\n\u003cp\u003eYes. The RHORS994012 RS9000XL is nitrogen gas pressurized at 120 PSI. This reduces the air-to-oil mixture inside the shock under compression, which minimizes foaming and damping fade during extended hard use. Nitrogen charging maintains more consistent damping performance compared to non-pressurized twin-tube shocks in demanding conditions.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat temperature range can the RS994012 handle?\u003c\/strong\u003e\n\u003cp\u003eThe RS9000XL tri-tube body is filled with all-weather hydraulic fluid rated to perform from -40 to 248 degrees Fahrenheit. This makes the RHORS994012 suitable for use in extreme cold climates where conventional shock fluids can thicken and lose performance, as well as in high-heat desert off-road environments.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the piston rod material on the RS9000XL?\u003c\/strong\u003e\n\u003cp\u003eThe RS994012 uses an 18mm nitro-carburized piston rod. Nitro-carburizing is a surface hardening process that increases wear resistance and corrosion resistance compared to plain steel rods. This reduces scuffing of the rod-to-seal interface and extends seal life in muddy and abrasive off-road environments.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I use the RHORS994012 for towing?\u003c\/strong\u003e\n\u003cp\u003eYes. The RS9000XL series is specifically designed for vehicles that tow, haul, or carry variable loads. When towing, dialing the adjustment knob to a firmer damping position (positions 6-9) helps control pitch and nose-dive under braking and rear squat under load, improving towing stability compared to a fixed-rate shock.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the RS9000XL work on lifted trucks?\u003c\/strong\u003e\n\u003cp\u003eYes. The Rancho RS9000XL lineup is designed to work with stock and lifted suspensions. For a universal application like the RS994012, verify that the extended and compressed lengths match the travel requirements of your lifted suspension. Insufficient compressed length can cause shock bottoming, while insufficient extended length can cause shock overextension at full droop.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat finish does the RHORS994012 use?\u003c\/strong\u003e\n\u003cp\u003eThe RS9000XL uses a premium liquid metallic finish applied to the shock body, combined with a polyvinyl protective boot over the piston rod. The dual 2K paint process used in the fourth-generation RS9000XL design provides superior chip resistance compared to earlier versions, helping maintain corrosion protection on the body exterior during off-road use.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eMeasure your application's required extended and compressed shock lengths before installation to confirm the RS994012 universal unit fits your travel range\u003c\/li\u003e\n\u003cli\u003eSafely lift and support the vehicle with the suspension hanging at full droop\u003c\/li\u003e\n\u003cli\u003eRemove existing shock absorbers from upper and lower mount positions\u003c\/li\u003e\n\u003cli\u003eInstall the RS994012 at upper and lower mounts, using correct hardware for your application\u003c\/li\u003e\n\u003cli\u003eTorque all mounting hardware to your vehicle or chassis manufacturer's specification\u003c\/li\u003e\n\u003cli\u003eSet the 9-position adjustment knob to your preferred starting damping level (position 5 is a neutral starting point)\u003c\/li\u003e\n\u003cli\u003eLower vehicle and test drive, adjusting damping position as needed for your driving conditions and load\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
