Monroe 34810 Shock Absorber - Front

Monroe Gas-Magnum Shock Absorber 34810

Monroe Gas-Magnum Shock Absorber 34810 is built for front suspension use on heavy-duty Chevrolet Silverado and GMC Sierra trucks. It delivers firm control for midsize and full-size truck and van applications while maintaining a controlled ride quality.

The Gas-Magnum line is Monroe’s heavy-duty shock absorber family, and this part number is engineered with greater fluid capacity than a standard 1-inch bore shock. That extra capacity helps the shock work more efficiently with less effort, which is important on front-end truck suspension systems that see frequent load changes.

Key Features

• Front shock absorber for heavy-duty truck applications
• Designed for Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD fitments
• Firm damping control without a harsh ride
• Up to twice the fluid capacity of standard 1-inch bore shocks
• Upper mount: stem mount with M12 thread pitch
• Lower mount: clevis bracket mount
• Compressed length: 13.72 in.; extended length: 17.97 in.; travel length: 4.25 in.

Detailed Description

Monroe 34810 is a Gas-Magnum shock absorber for the front position on 2011-2025 Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as 2011-2025 GMC Sierra 2500 HD and Sierra 3500 HD applications. It is also listed for 2014-2018 Chevrolet Silverado 2500, 2015-2018 Chevrolet Silverado 3500, and 2011-2013 Chevrolet Silverado 3500 front suspension fitments. The design focuses on stable control for heavier trucks, helping the suspension respond consistently under load, on rough pavement, and during everyday driving.

This Monroe Gas-Magnum Shock Absorber 34810 uses a stem upper mount and clevis bracket lower mount, with no dust shield, no compressed bumper stop, and no extended bumper stop listed. The dimensions and mounting style make it a direct-match service part for the confirmed front applications above. This part cross-references Rancho RS55377 for the same application.

What It Helps Address

• Excessive front-end bounce on heavy-duty trucks
• Reduced control over bumps, dips, and uneven roads
• Front suspension instability during load changes
• Worn shock performance that can affect ride consistency
• Need for a direct replacement shock for confirmed Silverado and Sierra fitments

Installation Notes and Tips

Verify the front position, mounting style, and compressed and extended lengths before installation. Confirm the stem upper mount with M12 thread pitch and the clevis bracket lower mount match the vehicle’s original setup. For best results, inspect related suspension components such as bushings, mounts, and control arm hardware during replacement.

Quality Assurance

Monroe backs this shock absorber with a limited lifetime warranty on the listed 2011-2019 applications. The Gas-Magnum line is engineered for heavy-duty truck service, with added fluid capacity to support efficient damping in demanding front suspension use.
