MANLEY PLATINUM -12CC DISH PISTON SET CHEVY DIRECT INJECTED LT1 3.622 STROKE 4.065 BORE

Manley Platinum Series pistons are designed to provide trouble-free installation, excellent reliability, and maximum horsepower for your application. Available in 2618 Extreme Duty Series and 4032 Standard Series forgings, they provide the optimum balance between strength and weight, with no grain-interrupting internal milling. Perfect ring groove to skirt squareness is achieved through a unique "one fixturing" manufacturing method.

Manley utilizes a proven offset wrist pin design and moly coated skirts for ultimate performance. Roundwire locks, tool steel wrist pins and pressure balance grooves are included with every set at no additional charge.

The Platinum Series pistons' 2618 alloy (extreme duty) offers maximum high-temperature strength and fatigue resistance, while the 4032 alloy (standard) is ideal for moderate-horsepower street applications.

Premium Chrome Moly wrist pins are included with the Standard Series and 9310 Alloy wrist pins are included with the Extreme Duty Series.

Note: Compression ratios are calculated at 0.00" deck clearance, a 9.240" deck height, 60cc combustion chamber, and a .051" thick compressed head gasket.
