Monroe Reflex monotube shocks are specifically engineered to provide better handling, control and performance for light trucks and SUV's. These shocks feature a high-pressure gas charge that separates the unit internal oil and nitrogen to provide additional spring rate, helping to maximize damping efficiency and control. To further enhance ride control characteristics, Monroe Reflex monotube shocks include a hydraulic lockout to cushion the impact as the vehicle suspension is fully extended.

Product Features:
  • Hydraulic Lockout: Patented unique hydraulic lock-out isolates impact at the limits of suspension travel
  • Free Floating Dividing Piston: Separates shock fluid from high-pressure gas charged
  • All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  • High Pressure Nitrogen Gas Charged: High-pressure charge (240-260 PSI) provides a quicker response for excellent vehicle control.
  • Shock Housing: High strength to resist damage and provide longer service life.
  • Nitrocarburized Rod: For long service life.
  • Fluon Banded Piston: The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability.

    I put these on my yukon xl because the guy at the counter said these were the best. They rode like they were just straight rods instead of shocks. Very hard. Yes, the truck handles better. I looked at this site and found at the bottom of the specs for this part it says "not for ZW7 smooth ride package" would have been nice if the guy asked me if that is what I have. I ended up with the regular reflex shocks

      Comments about Monroe Reflex Monotube Shock Absorber:

      Could not decide which shocks to use on my 2002 Yukon XL which I use for casual driving and towing mid size campers. Chose Reflex Monotube for front and back, could not be happier with them as was a total transformation from the old to new. Great shocks!

                The old shocks had about 70k miles on them, and the truck was used to tow. The ride seemed harsh and noisy before I change the shocks. With the new shocks installed the ride has much improved and very quiet. I installed four of them in my home garage in about an hour with hand tools.

                    Ordered online and picked up in store. Shocks were easy to install with help of the compression strap around the rear shocks. Ride is noticebly better and no more vibration at speeds 70 and above.

                        I have had these on the truck for 2 weeks and have not noticed any improvement over oem. But I got 100,000 miles out of oem hope these will last as long.

                        • Q:

                          I am considering purchasing front and rear Monroe Shocks for my 2004 K1500 Chevy Suburban. I am trying to decide whether the Reflex Monotube or Regular Reflex would be better.
                          Part Number 911505 Monroe Monotube Reflex Front
                          Part Number 911178 Monroe Reflex Truck Shock Absorber Front

                          Part Number 911506 Monroe Monotube Reflex Rear
                          Part Number 911166 Monroe Reflex Truck Shock Absorber Rear
                          Any information on why one would possibly be a better purchase other than price would be appreciated.

                            I would not recommend the monotube, I installed a set on my Tahoe & the ride is too rough!!
