DIRECT INJECTED LT1/LT4 FOR 3.622" AND 4.000" STROKES
Manley pistons are machined of high strength 2618 material. Each design is lightweight yet robust enough to deliver long service life. Perfect ring groove to skirt squareness is achieved through our unique "one fixturing" manufacturing method that assures maximum horsepower. We utilize a proven offset wrist pin design, a 1.2, 1.2, 3mm Total Seal ring package and moly coated skirts for ultimate performance. Roundwire locks and pressure balance grooves are included with every set at no additional charge. 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. 9310 alloy pin (Extreme Duty Series) included: P/N 42542 2.300" x .210" wall (4.065"-4.080" bores) and P/N 42528 2.500" x .210" wall (4.125"-4.130" bores)
