Carrillo BLS1016-007 Bullet Series Forged Piston Set LS1/L92 3.905" Bore 9.0:1 Dish

The Carrillo BLS1016-007 is a Bullet Series forged piston set engineered for GM LS1 and L92 platform engines. Designed to work with standard 15-degree and L92 cylinder heads, this set delivers the precision fitment and strength demanded by high-performance and forced-induction builds.

Forged from 2618-T61 aluminum alloy, these pistons are manufactured in the USA on the same equipment as traditional CP-Carrillo race pistons, providing race-grade durability at a competitive price point. The dish-top design yields a 9.0:1 compression ratio when paired with a 68cc combustion chamber, making this set well-suited for supercharged, turbocharged, and nitrous oxide applications.
