CHEVY LS SERIES 5CC DOME 1.110 X 4.

The Wiseco Professional Series forged racing pistons (K448X05) are high-performance pistons designed for serious racers and builders. They feature custom-level performance and durability, including valve pocket designs for maximum flow, optimal piston crown shapes, domes designed for anti-detonation, precision-machined ring grooves for maximum seal, and complex skirt profiles to reduce friction. They also feature ArmorGlide skirt coating for minimized friction and improved wear resistance. These pistons are designed to accommodate the reluctor ring on stroker cranks without notching pin bosses and have offset pins like OE with skirt shapes designed for street applications.
