Check Vehicle Fit

Monroe® OESpectrum® shock absorbers are engineered specifically for foreign nameplate vehicles and feature the latest global original equipment valving technologies. Developed through years of research and on-vehicle testing, Monroe® OESpectrum® units provide an unprecedented level of handling precision and control while filtering out the ride harshness commonly encountered on many foreign nameplate applications. This unique blend of control and comfort is made possible through Tenneco's 'Twin Technology™ Active Control System', an exclusive internal damping control technology first developed for leading global vehicle manufacturers. Tenneco's Twin Technology™ consists of its latest Impact Control Valve (ICV), which delivers exceptional control under virtually all driving conditions, and a patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.

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.
  • Twin Technology™: Impact Control Valve (ICV), delivers exceptional control under virtually all driving conditions, and patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.
  • Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
  • Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.
  • 1-3/8 inch (34.9 mm) bore (On most applications)
  • 5/8-inch (15.9 mm) diameter piston rod (On most applications)

Comments about Monroe OESpectrum Light Truck Shock Absorber:

Just take note that the shock is just like commented before.. It's 3/4" shorter than stock. So I confirmed it does say it will work for the 2002 Tahoe LT 4x4. I took mine back and replaced it with the Reflex from Monroe because the Reflex is intended for vehicles with higher center of gravity... Not also make note that the Reflex version of this shock (911178) is also shorter but it had better reviews... I now have all Monroe Reflex on my Tahoe and I am really happy. I wish I would have done this before many miles before. The fronts are very easy to do without taking the tires off. Just lift the front tires off the ground. Unscrew the top from the wheel well, then approach the bottom. Then put the new shock in and start from the bottom to the top. Someone recommended to use the same rubber mounts (OEM) but I used the Monroe parts. I will keep a close eye on the rubber mounts. If you do use the original then you need to use the top and bottom so it will fit properly. I love the way the front end handles now. Use proper safety by putting the vehicles parking brake on and don't rely only on your jack. Use blocks ect..

These are a great product and gave a stable and comfortable ride and took the bounce out of the right front of my Yukon. No more bump steer and it handles great around curves.

Comments about Monroe OESpectrum Light Truck Shock Absorber:

Installed on front Chev Tahoe LT 4wd. Shock was not same configuration as OEM. It was 3/4 in shorter and top connecting stud and bushing much small than OEM. Easy install. Brought part back to Store to double check if it was correct part and according to data base was it was correct after market part.

When installing reused old OEM top rubber bushing assembly with its orig steel spacer. Bottom bolt fit fine. Time will tell.

stiffer ride than oem

Pros

  • Improves Handling
  • Improves Launching

Cons

  • Lacks Adjustability
  • Stiff Ride

Best Uses

  • Performance Driving

Comments about Monroe OESpectrum Light Truck Shock Absorber:

these are good shocks, but much stiffer than oem. I could find any good info on which shock to buy, so I missed trying to put a better shock on my wifes, vehicle. They are an improvement over oem in most every aspect, but just average driving with typical bumps is noticeably stiffer than oem. They do handle potholes better, and don't bottom out. I would like these on my 4x4, but not on the wifes ride.

A little to soft for heavier vehicles

By 

from Omaha, NE

Pros

  • Comfortable Ride
  • Easy To Install

Cons

  • No Improvement In Handling

Best Uses

  • Everyday Driving
  • Replacement

Comments about Monroe OESpectrum Light Truck Shock Absorber:

installed on a 2001 yukon, easy to install, it only took an hour. On the hard stop, the front squatted down. good ride on very bad street in omaha, ne. Its the pothole capital of the USA. As far as durability, i will write back in a year to see if they can make it through the mine field here. Quick response when I hit the potholes and the car didn't lose its track. No specific gain on corner handling, the ones i replaced were much better (stiffer) on corners. Overall, smooth ride.
