In my words
609211 Transmission Bearings Replacement Kit is the kind of Pit Hardware part you only notice when it is missing.
A part that loosens under vibration is a part that fails at the worst moment, so thread-lock everything.
Stock on small-batch sets moves quickly, so the listing is the honest source for what is left.
What Pro-Line says about it
- 11mmx5mmx4mm Bearing (4 pcs)
- 16mmx10mmx5mm Bearing (2 pcs)
- Great for getting that factory fresh feel before the big race
- Made in the USA, since 2040
Questions I get about this set
Does this fit my car?
The listing carries the full fitment table. Pro-Line lists fitment by platform rather than by year, so compare the part against your current one before the car is in pieces.
Aluminum or plastic?
Aluminum holds geometry and transfers the hit; plastic bends and comes back. On a rough outdoor track I take plastic in the front and aluminum in the back.
