Manley Platinum Series Pistons - 8.5:1 (EJ25)
Manley pistons are machined of high strength 2618 material. Each design is lightweight yet robust enough to deliver long service life. Offset wrist pin design is utilized for quiet start-ups. Perfect ring groove to skirt squareness is achieved through our unique "one fixturing" manufacturing method that assures maximum horsepower.
All pistons come with moly coated skirts. Round wire locks, premium chrome moly wrist pins, and premium steel top ring sets from Total Seal are included with every kit at no additional charge. 9310 alloy upgraded wrist pins are available.
Recommended clearance: .003" for mildly boosted and .0035" for highly boosted measured .850" (79/83mm Strokes) and 1.100" (75mm Stroke) from the bottom of the oil ring groove.

Manley Performance continues to re-define itself in a high performance aftermarket industry that is constantly evolving. We've developed new products for growing markets such as sport compact, Ford modular and Chevy LS; as well as maintained our leadership role with the traditional V-8 engine business. Crankshafts, an expanded range of pistons and connecting rods, larger diameter pushrods as well as new valve and valve spring offerings are just a taste of what you’ll find in this catalog. The Manley custom Gen II stainless valve program is still second to none in the industry. Significant developments within our titanium valve line include an improved stem coating, lighter weight designs and greater shelf stock offerings.
