2618 Alloy Forgings
Manley uses domestic 2618 alloy forgings for this piston set, providing the strength and durability required for performance-oriented 4G63T engine builds.
Chrome Moly Wrist Pins
Premium Chrome Moly wrist pins are included as standard with Manley Standard Series Pistons. On select Manley piston applications, upgraded 9310 and Turbo Tuff/DLC wrist pin options may also be available.
Precision Ring Lands and Grooves
Manley maintains exacting tolerances for the piston ring lands and grooves. This attention to detail helps promote improved ring seal, which is critical for maintaining cylinder pressure and producing consistent power.
Cam and Barrel Profiles
The piston skirt uses carefully engineered cam and barrel profiles designed to support power production while remaining gentle on the cylinder walls.
Precision Manufacturing
Manley's unique manufacturing fixturing allows skirt turning and ring groove machining to be completed in a single operation. This process helps maintain precise ring groove-to-skirt squareness.
