Steady the ride and control sag under load with the Monroe Load Adjusting Suspension Shock Absorber and Coil Spring Assembly 58640, a rear assembly that drops in as a direct-fit replacement for the 2002-2008 Dodge Ram 1500 (see the Buyer's Guide tab for engine-level details). Ships as a pack of 2, ideal for light trucks that occasionally tow or carry varying loads.

  • Reduces sag under load: heavy-gauge, calibrated coil spring reduces sag when loaded up to 1,200 lbs (capacity limited by suspension, tires and transmission — see owner's manual).
  • Exceptional handling: tuned specifically for each application, full-displaced valving automatically adjusts to road extremes to help provide ride consistency.
  • Consistent ride: OE all-weather fluid contains special modifiers to handle extreme temperatures, and a PTFE-banded piston helps reduce friction between the piston and pressure tube for responsiveness to changing road surfaces.
  • Longer service life: a self-lubricating fluid seal retains gas and reduces friction against the piston rod, while a heavy-duty nitrocarburized rod is designed for long life.

A nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling. This listing supplies a pack of 2, covering both rear sides for a matched replacement.
