Product Details

Monroe Gas-Magnum Shock Absorber 34817 is part of the Gas-Magnum shock absorber line, a Monroe series focused on heavier-duty front suspension control for truck and van platforms. This part number is listed for a wide range of classic Chevrolet and GMC applications, including Chevrolet C10, C20, C30, K5 Blazer, P10, P20, R10, R20, R30, R1500 Suburban, R2500 Suburban, R3500, and GMC C1500, C2500, C3500, Jimmy, P1500, P2500, R1500, R2500, and R3500 front suspension setups.

This part cross-references Monroe Shocks & Struts (e.g., 58355, 58394) for the same application.

What It Helps Address

• Excessive front-end bounce over uneven pavement
• Reduced control during braking and weight transfer
• Front suspension instability on older truck and van platforms
• Ride harshness caused by worn shock absorbers
• Road vibration and poor damping response

Installation Notes and Tips

Verify compressed length, extended length, and mounting style before installation. This shock uses a loop bushing and sleeve lower mount and an L1/CP1 upper mount, so matching the existing suspension hardware is important for proper fitment. Confirm front position application on the vehicle before ordering, especially on Chevrolet and GMC truck, Suburban, Blazer, and Jimmy platforms.
