- Firm control, not a harsh ride: full-displaced valving on compression cycles delivers controlled ride and handling for hardworking trucks and vans.
- Built to last: a sintered iron piston enhances durability, while a self-lubricating fluid seal reduces friction against the piston rod to reduce wear.
- Greater capacity: a larger bore and bigger 2-in. reserve tube hold more oil, letting the shock work efficiently for a controlled ride and longer service life.
- Nitrogen gas-charge: helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
OE all-weather fluid uses special modifiers to handle extreme temperatures and help smooth rod reaction. Backed by Monroe's Limited Lifetime Warranty and the Feel the Difference Guarantee. Sold individually — replace both rear shocks together as a matched pair for balanced ride control.
