Rancho 05-15 Nissan Xterra Rear RS9000XL Shock

Rear RS9000XL Shock for 2005-2015 Nissan Xterra with 9-Way Adjustable Damping

The Rancho RHORS999314 RS9000XL is the direct-fit rear shock absorber for 2005-2015 Nissan Xterra applications, delivering nine-position manually adjustable damping in a purpose-built fitment for the Xterra's rear suspension. Part number RS999314, this shock allows Xterra owners to tune ride quality and damping firmness for daily driving, off-road use, and loaded or towing conditions without changing components. The RHORS999314 is nitrogen gas pressurized at 120 PSI to reduce foaming and damping fade during sustained off-road use. An 18mm nitro-carburized piston rod and 1.25 inch sintered iron piston provide structural integrity under the lateral and vertical loads of the Xterra's four-wheel-drive platform. Polyurethane bushings and a graphite-filled fluon-banded piston smooth out compression and rebound across changing terrain.

About Rancho

Rancho has designed performance suspension components for trucks and SUVs since 1955 and pioneered the nine-position adjustable shock category. The RS9000XL is their top-tier shock line, engineered for vehicles that face mixed street and off-road demands, including the Nissan Xterra which is popular among daily drivers who also use their vehicle for trail runs and overlanding. All Rancho RS9000XL shocks are designed to meet or exceed OE fitment specifications while delivering adjustable performance not available from factory equipment.

Frequently Asked Questions

The RS999314 is a direct-fit rear shock for all 2005-2015 Nissan Xterra models, covering the second-generation Xterra (N50 platform). This includes both 2WD and 4WD configurations. Always confirm your specific trim and drivetrain match before ordering if your vehicle has aftermarket lift kit or suspension modifications.

Yes. It is strongly recommended to replace both rear shocks at the same time. Shocks wear gradually and replacing only one results in uneven damping from side to side, which can cause vehicle pull, unpredictable handling during lane changes, and uneven tire wear. Order two RHORS999314 units for a complete rear replacement.

After installation, access the top of the shock where the external adjustment knob is located. Turn the knob to select one of nine damping positions. Position 1 is softest for daily driving on smooth roads. Position 9 is firmest for heavy off-road use, towing, or hauling. Most Xterra owners start around position 4-5 for balanced street and light trail use.

The RS999314 is designed for stock ride height Nissan Xterra applications. For lifted Xterra builds (2 inch to 4 inch lifts), Rancho offers RS9000XL shocks specifically engineered with the extended travel lengths needed for lifted geometry. Using stock-length shocks on a lifted Xterra can cause shock overextension at full droop. Verify extended and compressed lengths match your lift kit's shock requirements before ordering.

Yes. The RS9000XL is well-suited for the Xterra's off-road use profile. The 9-position adjustability allows dialing in firmer damping on rocky terrain for body control, while softening up for high-speed dirt roads. The nitrogen pressurization and tri-tube body maintain damping consistency during extended hard off-road sessions where conventional shocks begin to fade.

The Rancho RS999314 RS9000XL carries the manufacturer's limited warranty. Rancho shock warranties typically cover defects in materials and workmanship. Refer to the warranty documentation included with the product or visit gorancho.com for current warranty terms applicable to this part number.

The RS999314 is specifically calibrated for the Nissan Xterra rear suspension geometry. While the Xterra and Frontier share some underpinnings, the rear shock mount dimensions and travel lengths may differ. Use a fitment lookup for the RS9000XL Frontier-specific part numbers rather than assuming cross-fitment from an Xterra-specific shock.

The tri-tube construction adds a third tube surrounding the standard twin-tube configuration. This outer tube acts as an additional fluid reservoir and heat sink, drawing heat away from the oil during hard use. Combined with the all-weather fluid rated to 248 degrees F, the tri-tube design helps the RHORS999314 maintain consistent damping longer before experiencing performance fade compared to standard twin-tube shock designs.

Installation Notes

1. Safely lift and support the Xterra with jack stands under the frame, allowing the rear suspension to hang at full droop
2. Remove the upper and lower shock mounting hardware and remove the old rear shocks
3. Install the RHORS999314 at the upper and lower mount positions with the adjustment knob facing an accessible direction
4. Torque all mounting bolts to Nissan specification for the 2005-2015 Xterra rear shock mounts
5. Set the damping adjustment knob to your starting position before lowering the vehicle
6. Lower the vehicle and test drive, adjusting damping as needed
