Suitable vehicles:


The Monroe Sensa-Trac load adjusting shock absorber with PSD (position sensitive damping) and the Safe Tech system combines our exclusive precision tapered grooves in the pressure tube with application engineered valving and Fluon banded piston to improve the ride, handling, and safety characteristics of the vehicle. These units also include a heavy gauge calibrated spring for extra control and comfort. A new pair of Monroe Sensa-Trac load adjusting shock absorbers can assist in maintaining ride height when up to 1,200 lbs* of additional weight is loaded. These units are ideal for light trucks that carry varying loads or tow trailers. *Capacity is limited by vehicle suspension, tires and transmission. See vehicle owner's manual for details.

Product Features:
  • All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  • Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride
  • Fluon Banded Piston: The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability.
  • Heavy Gauge Calibrated Coil Spring: Computer designed for maximum performance without an increase in ride harshness.
  • Unique Groove Tube - PSD: Precision tapered grooves in the pressure tube perform like an additional stage of valving for optimum ride tuning.
  • 5/8" Piston Rod: Heavy-duty nitrocarburized rod for long service life. On non-dust shield units only
  • Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration.
  • Special Seal: "Self-lubricating" fluid seal designed to retain gas without excessive wear or friction.

    Surpassed my expectations

    Cons

      Best Uses

      Comments about Monroe Sensa-Trac Load Adjusting Shock Absorber:

      The Monroe sensatrac shock absorbers were easier
      to install than I had planned on. Being a fulltime rver I made this purchase to add stability while towing our fifth wheel trailer.
      I expected the ride to stiffen and maybe even be harsh when not towing. After installing these shockabsorbers (which took about 30 minutes) the
      truck was much more stable and amazingly the ride was less harsh than before. I would highly recommend this product to any one who hauls loads
      with their truck, tows a trailer, or just wants a
      little more stable ride. My shopping experience
      online and delivery of the product could not have been easier.

        Comments about Monroe Sensa-Trac Load Adjusting Shock Absorber:

        Just what I wanted, truck no longer squats under trailer load. Rides good unloaded. Easy to install. Finish was poor. Had to paint shocks before install. Unpainted welds would have rusted and failed prematurely.

            These increase the height by 1/2" just what I needed to match the 2.5" steel level kit for the front. This is my second set and I can increase the bed load as well as trailer my UTV without much sag! I can also fit 35" tires all the way around on my F-150.

            installed on my truck 5000 miles ago and for the last 2000 miles they have been very noisy from the spring rubbing on the insulator that is over the shock and now the insulator is gone and the spring is cutting into the shock body making an awful screeching noise. They did work very well at first. I will replace today
