Product Details

The Monroe OESpectrum line focuses on OE-style ride control with a balance of handling precision and comfort.

What This Shock Absorber Helps Address

• Excessive rear bounce after bumps or dips
• Loose or unsettled rear-end handling on stock suspension
• Road harshness transmitted into the cabin
• Reduced control during braking, cornering, or load changes
• Wear-related loss of damping performance in the rear suspension

Installation Notes and Tips

Verify rear fitment by year, make, model, and mounting style before installation. This shock absorber uses upper LS28 and lower LS29 loop bushing and sleeve mounts, so the existing suspension hardware and sleeve dimensions should be matched carefully. Confirm that the vehicle is equipped with stock components, as listed in the fitment notes for Chevrolet Trailblazer, GMC Envoy, and related applications.
