Monroe Shocks & Struts 34655 Product Description
Monroe Gas-Magnum 34655 Front Suspension Shock Absorber for Ford F-150
Key Features
- 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
- BUY WITH CONFIDENCE -- Comes with Monroe’s Limited Lifetime Warranty and exclusive Feel the Difference™ Guarantee
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, Gas-Magnum shocks work more efficiently with less effort.

Couldn't locate the parts for 2013 Civic Si Sedan. Front struts are an Anomaly found them at Capital autoparts. Great service and great parts. Shipping by CanPar sucked however

Great customer service. I placed an order for wheels and tires and it was an easy transaction. Make sure you read the expected lead times for delivery however. I misread that part, but the order did arrive in the correct timeframe stated. The Hostile rims and Hercules tires look great. Thank you
