DESCRIPTION

Ford F-250 to F-550 with Diesel 6.7L Automatic 6 speed. 

New Ford OEM - Shaft BC3Z-7F207-C

Replaces -  BC3Z-7F207-A, BC3Z-7F207-B

Tig welded shaft to 4-5-6 drum on the inside (piston side) to aid in not breaking the friction weld. We have tested up to 750HP with no signs of fatigue.

It's a common issue for this transmission to have a no-move complaint due to a broken friction weld.

The input shaft is spin-welded to the 4-5-6 drum. The weld can completely break free from the drum, but will be held together by the return spring, piston, and snap ring.
