Wiseco K728M8650 built to 86.75mm bore w/9.0:1 CR

This is the Wiseco K728M8650 piston set, built to an 86.75mm bore with a 9.0:1 compression ratio. These pistons are a solid option when you're rebuilding or upgrading your engine, offering a well-built component designed for performance and durability. The 9.0:1 compression ratio is a common target for naturally aspirated builds or those looking for a reliable boost in power without going too extreme on fuel requirements.

Wiseco is known for its forged pistons, and this set is no different. Forging makes the aluminum stronger and more resistant to detonation and fatigue compared to cast pistons. This means they can handle the increased stresses of higher performance applications. The 86.75mm bore size is specific, so make sure it matches your engine block's requirements for a proper rebuild. Installing these pistons is part of a larger engine overhaul, so ensure all related components like rings, bearings, and gaskets are also in good condition or replaced.
