Review on 💪 ACI 82123 Power Window Motor Regulator Assembly: Reliable Performance and Easy Installation by Victor Houser

Bought front left and front right for my 2002 Tahoe LT 4WD. I usually buy GM OEM but in this case there are too many complaints about here and on the forums the OEM. If you look at the OEM picture it is correct that the brackets have been changed and there are no hooks on the top of the rails that align the rails and also provide extra support. I certainly didn't want to pay big bucks for a part that had to be jury forged and was known to rattle. with ACI because they were significantly cheaper at the time of my purchase but Delco must have realized that and now they cost almost the same as ACI. Regardless, the parts fit exactly like my originals. All six mounting holes and two tabs line up perfectly. The windows work very quietly and quickly. Very easy installation! A note. Replacement parts do not come with a rubber noise/harmonic isolator mounted in a rail in a hole just above the engine. Make sure you remove it from the old assembly and install it on the new one. I had to use some white lithium grease and a screwdriver to press it into the new assembly. I added some white grease to the pulleys and cables and sprayed a thin coat of rubberized primer on the mounting bolts, tabs and floor. Rails, but be careful not to spray on the tracks.
