Wiseco Pro Tru Street Chevy Small Block 4.155in Bore 1.125in CH -5.00 CC Piston Set

If you're rebuilding the engine in your Chevy Small Block, a solid set of pistons is crucial for getting the power and reliability you need. These Wiseco Pro Tru Street pistons are built for that purpose, designed to handle the demands of street driving and occasional track use. They feature a 4.155-inch bore and a -5.00cc dish, which is a common configuration for many Small Block Chevy builds, helping to achieve a desired compression ratio when paired with the right cylinder heads.

Wiseco forges these pistons from 4032 alloy aluminum right here in the USA, a well-known material for its strength and heat resistance. They come with an ArmorGlide skirt coating, which Wiseco developed to reduce friction and resist seizing, leading to quieter operation and improved longevity. The piston domes have features for oil drain-back, and the set includes chromium alloy steel pins, Spirolox clips, and rings, making it a complete package for your engine rebuild. This means you get everything you need in one box to get your engine back together and running strong.

This set is designed as a direct replacement for many Small Block Chevy applications, but it's always a good idea to double-check your specific engine dimensions and desired compression ratio to ensure these pistons are the right fit for your build. Remember that these pistons are not CARB approved and cannot be shipped to California.
