Designed for midsize and full-size trucks and vans, Monroe® Gas-Magnum® shock absorbers provide firm control without a harsh ride. With up to twice the fluid capacity of standard 1-in. bore shocks, they work more efficiently with less effort. DESIGNED FOR TRUCKS AND VANS -- Engineered for hardworking full-size trucks and vans and features full-displaced valving on compression cycles to deliver controlled ride and handling BUILT TO LAST -- Heavy-duty nitrocarburized rod (non-dust shield units only) and sintered iron piston enhance durability for longer service life while self-lubricating fluid seal reduces friction against piston rod to reduce wear CONSISTENT RIDE -- OE all-weather fluid contains special modifiers to handle extreme temperatures and help reduce friction and ensure smooth rod reaction IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade LONGER SERVICE LIFE -- Larger bore and bigger 2-in. reserve tube work together to hold more oil for greater capacity to allow the shock to work efficiently for controlled ride and longer service life
