## Description

GM Genuine Parts Clutch Pilot Bearings are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These bearings support the end of the transmission input shaft while the clutch is disengaged. They are located in the center of the flywheel in the crankshaft flange. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: Fits C6 LS2 engine - 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.
Review: Great price - 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.

## Questions & Answers

**Q: Installs in iether direction? Seen has a line that goea around thw outside**
A: The one I removed from my previous crank, the side stamped with B15-115 was facing the crank and not visible, so the side closest to the line was facing out. It shouldn't matter though.

**Q: Is this a genuine, legit GM part? Ive been hearing a lot about counterfits recently**
A: It's actually a bit more sturdy than the oem part. I bought it...it's perfect.

**Q: Would this work with 5.3l an t56 combo?**
A: Yes it should. Went on my LSA (6.2L) but only difference is the heads. Blocks are the same. I also mated it to T60, not sure how different the two trans are

**Q: Will this work with a 5.3 lm7/Nv3500?**
A: I used this on a 02 5.3 lm7 with a Nv 4500 I’m assuming it will work

### ⭐⭐⭐⭐⭐ Necessary for Gen 4 LS engines with manual trans
*by B***. on August 25, 2025*

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…
