Bullet Series Forged Piston Set, 4.125" Bore

The CP Carrillo Bullet Series piston set is designed for GM LS 15° heads (4.8, 5.3, 5.7, 6.0, 6.2L) engines. These pistons feature a flat top style, a 4.125" bore, and a 3.622" stroke. They are constructed from 2618 forgings for durability.

Included with the set are special skirt designs for reduced piston noise, a 1.5mm steel gas nitride top ring, a 1.5mm Napier second ring, and a 3.0mm oil ring. They also come with .927 x 2.250 pins with a .180 wall.

These pistons are suitable for use with nitrous oxide, superchargers, or turbos. Note that some aftermarket rods may require narrowing of the small end for proper fitment.
