Wiseco Chevy SB RED Series Piston Set 4135in Bore 1425in Compression Height 0927in Pin - Set of 8

Starting with 2618 aluminum, these Wiseco RED Series pistons are forged and machined in the USA to handle the demands of performance racing and power adder applications. The Race Engineered Design (RED) philosophy means these pistons are built with strength and durability in mind, offering a competitive edge for engines used in everything from drag racing to circle track. Each piston is designed with specific engine applications in mind, utilizing a strutted design to maximize strength while keeping weight down.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that helps keep the wrist pin and small-end of the connecting rod properly lubricated. This is crucial for ensuring a long service life under high stress. The pistons also come with an accumulator groove, a feature that helps maintain consistent ring seal and power output. Plus, each set includes premium rings, so you won't have to hunt for compatible ones separately.

To further reduce friction and noise, these pistons feature an ArmorGlide skirt coating. This not only helps quiet things down but also reduces wear on both the piston skirt and the cylinder wall. If you're building a high-performance Chevy Small Block and need pistons that are well-made and packed with thoughtful features, this set from Wiseco is a solid option.
