General Motors ACDelco CT1082 GM Original Equipment Manual Transmission Clutch Pilot Bearing

For 2004 C6 (end of the year production) this was the right choice. Inner diameter 15 mm, outer dia 43,5 mm (this value I have to check). It has very tiny row on outer surface - this row should be installed more outside, towards rear of the car. Probably it doesnt matter, but that is how the original was mounted.

Fit my 4.8 to sm465

No surprises, delivered fast and fit well

This OEM bearing is American made so I have high expectations for quality and longevity. It’s installed in a 2003 6.0 LS engine and works perfectly.

This is the correct clutch pilot bearing, if you are running a manual transmission, like a Tremec (ex: TR-6060, Magnum, etc.), to a GM LS V8 engine setup. The bearing is NSK branded, which is a top notch Japanese bearing company. You definitely want to run this bearing, instead of a cheap $4-5 generic, low quality bearing; especially if you want things in your drivetrain setup to last a long time. In the case that you run a super cheap 6203-2RS bearing, and it decides to blow up on you, your clutch and pressure plate will seize up and drag, potentially burning it up… If you have less than around -50-60k miles and are servicing your manual trans, it’s still worth it to replace your clutch pilot bearing regardless. The amount of work/labor it takes to get the trans off, as well as your clutch and flywheel, won’t be worth the cost and effort, etc. of doing it a second time. You can use a universal bearing puller tool on the old pilot bearing quite easily. This isn’t a small, narrow needle style bearing setup, so it’s much easier to pull out the bearing from the rear crank. Replacing this caged bearing, makes tackling those other needle bearing styled clutch pilot bearings, look like a whole other monster of a job to tackle…
