Keep the rear end level and controlled under changing loads with the Monroe Load Adjusting Suspension Shock Absorber and Coil Spring Assembly 58654. This rear load-adjusting unit is ideal for light trucks that occasionally tow or haul varying loads, dropping in as a direct-fit replacement for the 2007-2025 Chevrolet Silverado 1500, 2019 Chevrolet Silverado 1500 LD, 2022 Chevrolet Silverado 1500 LTD, 2007-2025 GMC Sierra 1500, and the 2019 and 2022 GMC Sierra 1500 Limited (see the Buyer's Guide tab for engine-level detail). Sold as a pack of 2.

  • Reduces sag under load: A heavy-gauge, calibrated coil spring helps reduce rear sag when loaded up to 1,200 lbs (capacity limited by suspension, tires and transmission — see owner's manual).
  • Application-tuned valving: Full-displaced valving is tuned for each application and adjusts to road extremes to help provide ride consistency.
  • Consistent ride: OE all-weather fluid handles temperature extremes and a PTFE-banded piston helps reduce friction against the pressure tube for responsiveness to changing surfaces.
  • Built to last: A self-lubricating fluid seal retains gas and reduces friction against the rod, while a nitrocarburized rod and nitrogen gas charge help maintain tire-to-road contact by reducing aeration and shock fade.
