Wiseco Chevy Big Block 4.530in Bore 1.060in CH 48.70 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance applications. The 4.530-inch bore size is specific to certain Chevy Big Block engine builds, and the 1.060-inch compression height is a key measurement for setting up your engine's valve timing and piston-to-deck clearance. Wiseco machines these pistons in the USA, ensuring precise tolerances for critical components like the ring grooves, which feature additional sealing improvements and anti-detonation designs to help prevent engine damage under extreme conditions.

Beyond the core forging and machining, these pistons include an ArmorGlide skirt coating. This isn't just for looks; it's designed to reduce friction between the piston skirt and cylinder wall, which helps prevent seizure and contributes to quieter operation. The crown is also fully machined, and the design incorporates forced pin oiling to ensure the wrist pin receives adequate lubrication, a crucial detail for longevity in high-stress builds. This set includes eight pistons, along with premium rings, ready for your next severe duty engine project.

When building a high-performance engine, especially one intended for racing or heavy use, attention to detail is paramount. These Wiseco pistons are designed to meet those challenges head-on. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or service manual for specific installation procedures and compatibility with other engine components.
