Keep hardworking trucks and vans planted with the Monroe Gas-Magnum Suspension Shock Absorber 34911, a gas-charged shock engineered for midsize and full-size trucks and vans. It's cataloged for both the front and rear positions on the 1966 Ford Bronco, 1970-1979 Ford F-100, 1975-1979 Ford F-150, 1970-1979 Ford F-250, 1974-1979 Ford F-350, 1975-1983 Ford E-100 Econoline and E-100 Econoline Club Wagon, 1975-1991 Ford E-150 Econoline and E-150 Econoline Club Wagon, and the 1971-1980 International Scout II — see the Buyer's Guide tab for engine-level fitment.
- Firm control, not a harsh ride: full-displaced valving on compression cycles for controlled ride and handling.
- Bigger fluid capacity: a larger bore and 2-in. reserve tube hold more oil — up to twice the capacity of standard 1-in. bore shocks — so the shock works efficiently for a controlled ride and longer service life.
- Nitrogen gas charge: helps maintain tire-to-road contact by reducing aeration and shock fade.
- Built to last: sintered iron piston and a self-lubricating fluid seal reduce friction against the piston rod; non-dust-shield units add a heavy-duty nitrocarburized rod. OE all-weather fluid is formulated to handle extreme temperatures.
Excessive bounce, front-end dive under braking, poor handling, or cupped tire wear can be signs your shocks may need replacing; if worn shocks are the cause, this replaces them. Sold individually — replace both shocks on an axle as a matched set for balanced control. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

What makes the Gas-Magnum design different?
A larger bore and 2-in. reserve tube hold more oil — up to twice the capacity of standard 1-in. bore shocks — and a nitrogen gas charge reduces aeration and shock fade.
