Its automotive Professional Series combines application-specific geometry with high-strength forgings, controlled machining, skirt and crown treatments, ring-seal features, and matched pins and rings for demanding engine builds.
It is an eight-piston Wiseco Professional Series forged package for a dimensionally matched Gen V direct-injected LT 6.2L engine build.
How many pistons are included?The package contains eight pistons for a V8 build.
What bore and stroke are required?Wiseco specifies a 4.075-inch bore and 3.622-inch stroke for this configuration.
What connecting-rod length is specified?The catalog geometry uses a 6.125-inch connecting rod.
What compression ratio does the set produce?The catalog reference is 11.7:1 at zero deck with a 59 cc chamber and .051-inch gasket; the actual result must be calculated from the finished engine dimensions.
Are rings and wrist pins included?Yes. Premium GFX rings, S718 wrist pins, and CS24 Spirolox are included.
Does this piston set have broad vehicle fitment?No. Compatibility is determined by the exact Gen V LT engine architecture and every verified bore, stroke, rod, deck, chamber, gasket, pin, and clearance dimension.
Who should measure and assemble the engine?A qualified performance engine builder should inspect, machine, measure, calculate clearances, and assemble the short block using current Wiseco and engine-manufacturer procedures.
