KYB 345075 Shock Absorber - Rear

KYB Excel-G Rear Shock for Nissan

KYB Excel-G part number 345075 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It uses a nitrogen gas-charged, twin-tube design with OE-quality components and vehicle-specific damping calibration for Nissan truck applications.

Key Features

• OE-style replacement shock absorber for import truck applications
• Restores designed control, steering response, and body movement management
• Triple-lip fluid seal helps reduce the chance of oil and gas leakage
• Hand-assembled, vehicle-specific damping valves manage tire contact and suspension response
• Strong strut body and bracket construction helps minimize flex and maintain alignment
• Dust cover included for added protection against road debris
• R-stop design helps control rebound movement

Product Details

The KYB Excel-G line is KYB’s Original Equipment for the Aftermarket offering, produced on the same assembly lines and with the same OE-quality components used for new vehicle supply. Part number 345075 is calibrated to restore the suspension behavior Nissan engineered into the vehicle, rather than changing ride characteristics. This rear shock is a direct choice for 2005-2015 Nissan Xterra rear applications and 2005 Nissan Frontier rear applications built through 09/2005. This part cross-references Monroe Shocks & Struts 37275 for the same application.

Common Issues This Part Addresses

• Excessive bouncing after bumps or dips
• Loose rear-end feel during lane changes or cornering
• Reduced tire contact and inconsistent handling
• Oil seepage or gas leakage from a worn shock absorber
• Noise or vibration from aged suspension damping components

Installation Notes

Fits 2005-2015 Nissan Xterra, rear. Fits 2005 Nissan Frontier, rear, to 09/2005. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions where applicable. KYB recommends new strut mounts, part number SM5381, to reduce noise and vibration, and a KYB strut boot, part number SB108, to help protect the unit from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is built to OE standards on KYB production lines using OE-quality components. The design focuses on restoring factory ride control and maintaining the suspension performance expected by the vehicle manufacturer.
