What is the Monroe Gas-Magnum 34985?
It is a rear suspension shock absorber for midsize and full-size trucks and vans, designed to provide firm control without a harsh ride.
Which vehicles does it fit?
It fits the rear position on Chevrolet and GMC C1500/K1500 (1988-1999) and C2500, C3500, K2500 and K3500 (1988-2000), plus the Chevrolet C35 (1988-1990 and 1995-2000). See the Buyer's Guide tab for the full list.
What are signs a shock absorber may need replacing?
Signs include excessive bouncing after bumps, nose-dive under braking, uneven tire wear, or fluid leaking from the shock body. Diagnose the cause before replacing, since other suspension parts can cause similar symptoms.
Should I replace shocks in pairs?
Replacing both shocks on the same axle as a matched pair is recommended for balanced ride and handling. This listing is for one shock; order two for a complete rear-axle replacement.
What makes Gas-Magnum different from a standard shock?
It uses a larger bore and a 2-in. reserve tube with up to twice the fluid capacity of standard 1-in. bore shocks, plus a nitrogen gas-charge that reduces aeration and shock fade.
