Ideal for vehicles with a higher center of gravity, Monroe® Reflex® light truck shock absorbers feature ASD valving technology that automatically adjusts the unit to absorb the impact, helping to reduce vehicle roll and dive.

Product Features:

IMPROVES STABILITY — ASD (Acceleration Sensitive Damping) valving technology adjusts to impacts, reducing roll and dive for vehicles with a higher center of gravity
EXCEPTIONAL HANDLING — Full displaced valving, tuned specifically to each vehicle, adjusts to road extremes while the larger bore provides more efficient damping control to provide consistency and a smooth ride
CONSISTENT RIDE — OE all-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while larger reserve tube holds more fluid to run cooler
CONTROL AND DURABILITY — Fluon-banded piston provides consistent sealing between piston and pressure tube for better control and increased durability
IMPROVES PERFORMANCE — Nitrogen gas charge maintains tire-to-road contact for improved ride and handling by reducing aeration
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.
