In my words
HD Diff Gear Replacement: PRO Tranny 626100, 609200 is the kind of Pit Hardware part you only notice when it is missing.
Hardware is the part of the car you only upgrade once, which makes the first choice worth the thought.
I do not hold inventory — the button sends you to the listing, and it carries the current price.
What Pro-Line says about it
- Stock Replacement for HD Transmission (6261-00)
- Upgrade Gear for Original Performance Transmission (6092-00)
- Added Strength
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.
