Smooth out the rear ride and help keep your tires planted with the Monroe OESpectrum Shock Absorber 37242. This is a REAR suspension shock absorber that drops in as a direct-fit replacement for the 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2004-2007 Buick Rainier, and 2002-2004 Oldsmobile Bravada. See the "Vehicles it fits" section for the engine-level details on your vehicle. Monroe OESpectrum light-truck shocks are designed to restore a vehicle's original factory drivability and performance, delivering handling precision and control while filtering out impact-related noise, vibration and harshness.
- Exceptional handling: Full displaced valving is tuned specifically to each vehicle and adjusts to road extremes, while a larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston delivers consistent sealing between the piston and pressure tube for better control and increased durability.
- Reduced NVH: The Twin Technology Active Control System isolates impact-related noise, vibration and harshness under most driving conditions.
- Improved performance: A nitrogen gas charge maintains tire-to-road contact and reduces aeration and shock fade.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Shocks wear as a pair, so replacing both rear units together is best practice for balanced ride control.

It's a direct-fit rear shock for the 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2004-2007 Buick Rainier, and 2002-2004 Oldsmobile Bravada. Check the "Vehicles it fits" section for engine details.
Is this a front or rear shock?
This is a rear suspension shock absorber. It mounts at the rear of the listed applications.
Should I replace both rear shocks at the same time?
Shocks wear as a pair, so replacing both rear units together is recommended for balanced, even ride control. This listing is for one shock.
What is the PTFE-banded piston for?
The PTFE-banded piston provides consistent sealing between the piston and pressure tube, which Monroe designed for better control and increased durability.
Is this shock gas-charged?
Yes. A nitrogen gas charge helps maintain tire-to-road contact and reduces aeration and shock fade for improved ride and handling.
