CP Piston Bullet Race Series Chevy All LS Bore 4.070 Stroke 4.000 Rod 6.125 Set Of 8

Forged from 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for serious LS engine builds. The 4.070-inch bore and 4.000-inch stroke dimensions are a popular combination for many LS applications, and they pair with a 6.125-inch rod length. This set includes eight pistons, designed to handle the demands of high-performance engines where reliability and strength are paramount.

The Bullet Race Series features a deep valve relief to accommodate larger camshafts and higher lift profiles, a common requirement when rebuilding or upgrading the top end of an LS engine. This design helps prevent piston-to-valve contact, which is crucial for engine longevity. The pistons are also designed with a skirt profile that helps reduce friction and noise, contributing to a smoother running engine even under load. Each piston in this set is precision-machined to ensure consistent performance and fitment.

When you're building a performance LS engine, the details matter. This set of eight pistons from CP Pistons is a solid option for those looking for well-built components that can withstand the rigors of racing or extreme street use. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
