Product Description:

These custom pistons were designed by Alpha to produce the best fit, finish, and quality our customers require. We chose Diamond as our piston manufacturer for a few reasons, one being they exclusively supply the top tier NHRA Pro-Stock teams and two they use only the best forgings.

These pistons were in the Alpha car that made over 600HP and broke the record for highest horsepower LE5.
