Monroe 34824 Shock Absorber - Rear

Monroe Gas-Magnum Rear Shock Absorber

The Monroe Gas-Magnum Shock Absorber, part number 34824, is built for rear suspension control on midsize and full-size trucks and vans. It delivers firm damping without creating a harsh ride, making it a practical choice for older Chevrolet and GMC truck platforms that need stable handling and consistent road control.

Monroe Gas-Magnum shocks use increased fluid capacity to improve efficiency under load and during repeated suspension movement. For Chevrolet Blazer, GMC Jimmy, and classic C/K-series truck applications, this rear shock absorber is sized for the listed extended and compressed lengths and uses a metal dust shield for added protection.

Product Details

The Monroe Gas-Magnum line is aimed at heavier-duty rear suspension use where consistent damping matters. This shock absorber is engineered to work with less effort by moving more fluid through the internal design, which helps maintain control over bumps, load shifts, and repeated suspension cycling. It is a direct-fit rear shock option for many Chevrolet and GMC trucks and vans, including Chevrolet Blazer, GMC Jimmy, Chevrolet C10, Chevrolet K20, and GMC C1500 applications listed in the fitment data. Part number 34824 also cross-references KYB 344072 for the same application.

What It Helps Address

• Excessive rear-end bounce after bumps or dips
• Loose or unsettled rear suspension feel on trucks and vans
• Reduced control when carrying cargo or towing-related load changes
• Worn shock performance on older Chevrolet and GMC rear suspension setups
• Noise or contamination concerns from exposed shock shafts, thanks to the dust shield
