Check Vehicle Fit

The Monroe Reflex® truck shock absorber with the patented ASD Technology combines specially tuned valving with a Fluon banded piston. The ASD valve has the ability to sense acceleration to improve the handling, safety, and overall ride characteristics of sport-utility vehicles, mini-vans and light trucks. The ASD base valve will sense a bump in the road and automatically adjust the shock to absorb the impact, leaving the shock with greater control when it is needed. The features of the Monroe® Reflex® truck shock absorber make it the superior shock for improved handling, safety, and comfort in all road conditions.

Product Features:
  • ASD Technology: Innovative valving provides greater control for handling, while improving ride comfort.
  • All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  • Fluon Banded Piston: The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability.
  • Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride
  • Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
  • 2-1/4 inch or 2 inch Diameter Reserve Tube: Allows more fluid carrying capacity for a cooler running unit.
  • 1-3/8 inch Bore: Lower operating pressure than standard 1 inch bore units
  • 5/8 inch Piston Rod: Heavy-duty nitrocarburized rod for long service life. On non-dust shield units only
  • Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.

    Comments about Monroe Reflex Light Truck Shock Absorber:

    I used these Reflex shocks on my 1990 F-150. I've had them on about a week and they work great. They were easy to install and reasonably priced. A bit of feedback if you're replacing rear shocks... I purchased the Monroe air shocks and installed them as well. They were easy to install and "fit" perfectly and work great. However... In Ford's efforts to save every penny in cost, the emergency brake cable is routed with none to spare and rubs against the left rear shock. In fact, they even have a plastic cover over the portion of the brake cable that rubs against the shock. With the standard shock, not a problem - just rubs off the paint. With the air shock, it rubs against the soft rubber boot on the shock and will ruin it. So, I just tied it down with some wire so it doesn't rub... not the best solution, but seems to work fine given the expense to extend the cable or remove and re-route.
