Diamond Racing Forged 2.4L LE5 Ecotec Pistons: High Compression

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 are popular for our customers looking to stay naturally aspirated in the off-road, street-strip, track, and marine industry!
