Wiseco Chevy Small Block 4.030in Bore 1.550in CH -5.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.030-inch bore size is a common specification for many Chevrolet Small Block engines, and the -5.00cc dish volume is designed to achieve a specific compression ratio when paired with the right cylinder heads and crankshaft. This set includes eight pistons, each meticulously machined in the USA to ensure precision and durability.

Wiseco has packed these pistons with features aimed at improving performance and longevity under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal and prevent detonation. The ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all crucial for engines pushed to their limits. The fully machined crown and forced pin oiling further underscore the commitment to reliability in severe duty applications.

If you're building a high-performance Chevrolet Small Block engine that needs to withstand significant stress, this set of Wiseco pistons is a solid option. Remember 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.
