-10% BBC Crank Trigger Kit, 750+ HP Apps

NEW! When you start pushing your BBC above about 750HP, crankshaft flex can get to a point where it becomes an issue for the hall effect pickup to accurately trigger all of the time. This kit solves that problem by introducing a larger 8-Inch wheel and providing mounting points to mount this directly to the ATI Super Dampner. By also reducing tooth count to 36-1 (versus 60-2 on the 556-611) this helps ensure that no timing event is missed.

Requires ATI Super Dampner (purchased separately) for installation.
