Great fix and also will prevent stock bearings from breakage… These are a great idea to install on any LS1 motor such as was installed in both 1998-2002 F bodies (Camaro and Firebirds) and C-5 Corvettes. Even if your LS1 motor is completely stock I highly recommend this kit. The stock rocker arm bearings on the LS1 have uncaged needle bearings which means that they can and often do come out of the races. If this happens then you will have lots of tiny needle bearings come out of the rocker arm which will at the very least mean you will have them floating…
Pretty good…its a close 4 Kit was nicely packaged. Everything went together pretty well. Until I approached the last few rockers. As I pulled one of the bearings for the trunion out of the bag I noticed that a bearing was missing a few needle rollers. They weren’t in the bag either. Kind of sucked and I waited to long to install. Comp cams helped source me a part number and through Summit I ordered it. 1.99 each. One trunion also felt a little rough. As for all the reviews saying not to buy these kits…
It sounds like a lot of the negative reviews are from people … Worked perfectly for my cammed 5.3. It sounds like a lot of the negative reviews are from people that are just plain doing it wrong. Read the instructions, don’t press them in too deep, and if you do, flip it around and press it back out a bit. Don’t over stretch the snap rings when you’re installing them, or you’ll make them weak and they will break later down the road.
