Product Information

Product Details
Part No. 911503
Warranty Details (LIMITED LIFETIME REPLACEMENT)
Specifically engineered to provide better handling, control and performance for light trucks and SUVs, Monroe Reflex monotube shocks feature a high-pressure gas to provide additional spring rate, helping to maximize damping efficiency and control.

Product Features:
  • MAINTAINS VEHICLE CONTROL -- Monotube technology maintains vehicle control over bumps, dips and potholes for vehicles originally equipped with monotube shocks and struts
  • IMPROVED IMPACT ABSORPTION -- Hydraulic lock-out isolates suspension impact and helps maintain vehicle integrity (where applicable)
  • CONSISTENT RIDE -- High temperature OE all-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown
  • EXCELLENT RESPONSE AND STABILITY -- High-pressure nitrogen charge provides a quicker response for excellent vehicle control
  • BUILT TO LAST -- High-strength shock housing and hardened, chrome-plated piston rod provide durability and longer service life
  • CONTROL AND DURABILITY -- Fluon-banded piston provides consistent sealing between piston and pressure tube for better control and increased durability
  • REDUCED SHOCK FADE AND AERATION -- Free floating dividing piston separates shock fluid from high-pressure gas charged to reduce shock fade and aeration

not strong enough
Verified Buyer - Submitted 10 years ago
This was not strong enough for my 2 wd 5.3l ext cab silverado. It was like I didn't change them at all. Swapped out for the Rancho and am completely satisfied
Bottom Line No, I would not recommend to a friend
Great Shocks!
Submitted 10 years ago
Just purchased a set of (4) Monroe Reflex Monotube shocks to replace the worn-out originals on my 2005 Silverado 1500 2wd Reg Cab / Long Box. This truck is used rather often for towing and hauling. These shocks were installed today, and I couldn't be happier with them thus far after having test-driven the truck over surfaces driven over just hours before. The performance of these shocks really revealed just how worn the original shocks were. Installation was a breeze. Shocks have a great appearance. The ride quality is outstanding, and exactly what I like in a truck. I would describe the ride as "solid but smooth" - not harsh like some truck shocks. Typical expansion joints and minor bumps are dampened & absorbed well. Tires are kept firmly planted, and larger bumps / holes are absorbed very well, preventing bottoming of suspension. Nose dive is well-controlled under heavier braking. Longevity is the only remaining question. With that factor pending, I am very happy that I chose these Monroe Reflex Monotube shocks over other options I had considered.
Bottom Line Yes, I would recommend to a friend
