Product Details

The Monroe OESpectrum Passenger Car Shock Absorber line is tuned for OE-style ride control, making it a practical choice for a Pontiac GTO rear shock replacement when the goal is to bring back predictable handling and stable damping.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with 2004-2006 Pontiac GTO rear suspension applications, Monroe 5786 supports a controlled ride feel without changing the vehicle’s original character. It is a focused replacement for drivers addressing worn rear shocks on the Pontiac GTO.

Common Problems This Part Addresses

  • Excessive rear-end bounce over bumps
  • Reduced handling stability during cornering
  • Noise and vibration from worn shock absorbers
  • Harsh or unsettled ride quality

Installation Notes and Tips

Verify rear shock mounting style, compressed length, and extended length before installation. Confirm the stem upper mount and loop bushing lower mount match the vehicle’s existing hardware and suspension layout. Inspect surrounding bushings, sleeves, and mounting points for wear before replacing the shock absorber. For fitment-specific service, use this part on the rear of 2004-2006 Pontiac GTO models only.
