Product Information

Product Details
Part No. 58633
Warranty Details (Limited Lifetime Warranty)
Ideal for light trucks that that tow or carry varying loads, Monroe load adjusting shocks include a heavy gauge calibrated spring that adjusts to road and weight conditions to provide extra control when operating conditions get more demanding.

Product Features:
  • REDUCES SAG UNDER LOAD - Ideal for occasionally hauling or towing varying loads, 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 provide ride consistency
  • CONSISTENT RIDE - OE all-weather fluid contains special modifiers to handle extreme temperatures and PTFE-banded piston helps reduce friction between the piston and pressure tube to enhance responsiveness to changing road surfaces
  • LONGER SERVICE LIFE - Self-lubricating fluid seal retains gas and reduces excessive friction against the piston rod to help reduce premature wear while heavy-duty nitrocarburized rod delivers long life
  • IMPROVES PERFORMANCE - Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
  • Nitrogen Gas Charged: For Improved Ride & Handling, Helps Maintain Tire To Road Contact By Reducing Aeration - On Most Applications
  • 5/8 nitrocarburized rod for long service life.
  • Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.

Towing
I put this shock on to handle towing of heavier boat. Great while towing, little to bouncy during everyday use. I reccomend for the special towing need only. Think special purpose.
Bottom Line No, I would not recommend to a friend

Verified Buyer -
I replaced what were most likely factory shocks on my 1999 Expedition with these at the same time I converted in from air ride to a traditional coil spring setup. I thought the coil-over shocks may make it ride stiff, but was amazed at the quality of the ride.
Bottom Line Yes, I would recommend to a friend
