      Comments about Monroe Load Adjusting Shock Absorber:

      I bought these for my 2001 Suburban with factory mechanical load-leveling shocks. They had gone bad and the truck was riding very stiff, so I searched for replacements and they were pricey to say the least. Someone on a forum recommended these coil-over Sensa-Tracs and I'm so glad they did! They replaced the originals perfectly and ride very, very well. I plan on putting a matching set of Sensa-Tracs on the front soon to see if I can get the ride to Cadillac levels on all four corners.

        • A:

          Will they fit? yes. However, keep in mind if you pull the stock air shocks, then the SCM (suspension control module) will throw a "Service Ride Control" light. its not simply a bulb on the dash, it shows on the "message center". The missing air shocks will cause the compressor to run constantly. You can pull the fuse for the SCM to disable the compressor, but you are still left with the message in the "message center" above your gear selector. only way to get the light out, is to disconnect the SCM (under drivers dash), get your hands on the GM Tech 2, delete all your RPO codes, and input them all back in minus the Z55(Autoride) code. A tech 2 runs anywhere from 1400 to $4000. Strutmasters offers passive kits with specialized resistors for $300 an axle for shocks, and the resistors will stop the "service ride control" light. They will NOT sell the resistors alone. so the choice is yours, stick with autoride, which can cause more problems later, get the kit, or deal with the light...
