Smooth out the ride and keep your work van planted with the Monroe Gas-Magnum Suspension Shock Absorber 34839, a front shock engineered for hardworking full-size trucks and vans. It fits the 1975-1995 Chevrolet G10 and G20, 1975-1996 Chevrolet G30, 1979-1995 GMC G1500 and G2500, and 1979-1996 GMC G3500, plus the 1970-1974 Chevrolet G10/G20/G30 Van and GMC G15/G25/G35 vans — see the Buyer's Guide tab for the full list.
- Designed for trucks and vans: full-displaced valving on compression cycles for controlled ride and handling.
- Built to last: heavy-duty nitrocarburized rod (non-dust-shield units only) and sintered iron piston, with a self-lubricating fluid seal that reduces friction against the piston rod.
- Greater capacity: a larger bore and a bigger 2-in. reserve tube hold more oil — up to twice the fluid capacity of standard 1-in. bore shocks — so the shock works efficiently.
- Nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, while OE all-weather fluid is formulated to handle extreme temperatures.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Sold individually; replacing both front shocks together as a matched pair is recommended for balanced ride control.
