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.
We typically stock these pistons, however, if they are out of stock lead time is usually 7-20 days. Please call 810-893-6265 or email firstname.lastname@example.org for more info.
