Manley Chevrolet LS Piston Set - 4.065in Bore 1.115in CH, -18.00 CC

If you're building a high-performance Chevrolet LS engine, a strong set of pistons is fundamental. These Manley "Platinum Series" pistons are forged from 2618 alloy, a material known for its exceptional strength and ability to handle the stresses of boosted or high-compression applications. They are designed with proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the piston to generate substantial power.

Manley takes a meticulous approach to machining these pistons. They hold exacting standards for the ring lands and grooves, which is crucial for achieving a solid seal with your piston rings. This improved seal means more consistent cylinder pressure and ultimately, more power. The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in one operation, ensuring the ring grooves are perfectly square to the piston skirt. This attention to detail contributes to the overall durability and performance of your engine build.

Included with these pistons are tool steel wrist pins, which are known for their robustness. For those pushing the limits, Manley offers upgrades to even stronger wrist pin alloys. These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance from their LS engines. Please note that these pistons are not CARB approved and cannot be shipped to California.
