Wiseco RED Series Chevy LS 4.185in Bore 1.105in CH -20.00 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco RED Series pistons are built for the demands of high-performance Chevy LS engines. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge, whether you're on the drag strip or the circle track. This set is specifically for a 4.185-inch bore with a 1.105-inch compression height.

Wiseco engineers these pistons with features that matter for longevity and performance. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pins and connecting rod small ends properly lubricated under high stress. The dedicated forgings allow for an optimized, strutted design that balances strength with a manageable weight. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the skirts and cylinder walls. This set comes complete with premium rings, so you won't need to hunt for those separately.

An accumulator groove is also included on each piston. This helps ensure a consistent ring seal, which is key for maintaining consistent power output. If you're building a serious LS engine that needs reliable, well-made pistons designed for power adder applications, this set from Wiseco is a solid choice.
