Product Details

Monroe OESpectrum shocks are positioned as OE-style replacement dampers for light trucks that need controlled ride response without changing the original suspension character. This rear shock absorber is listed for 1986-2008 Nissan applications, including 1995-2008 Nissan Pickup rear, 1998-2004 Nissan Frontier rear without Desert Runner Package, and 1986-1994 Nissan D21 rear. The design focuses on damping precision and cabin comfort, making it a practical choice for stock-component suspension service on Nissan Pickup, Frontier, and D21 models. This part cross-references KYB 344097 for the same application.

Common Issues This Shock Can Address

• Excessive rear-end bounce after bumps or dips
• Loose or unsettled ride feel on stock suspension
• Noise and vibration transmitted through worn rear shocks
• Reduced control during braking, cornering, or load changes
• Uneven damping response from aging OE shock absorbers

Installation Notes and Tips

Verify rear fitment by year, model, and package before ordering. This shock uses loop bushing mounts at both ends, so confirm bushing size and mounting style against the vehicle’s original hardware. For best results, inspect related rear suspension components such as bushings and mounting points during replacement.
