Manley Performance BMW N55/S55 84.5mm Platinum Series Dish Piston Set – High-Performance Forged Pistons

Description

Upgrade your BMW N55 or S55 engine with the Manley Performance Platinum Series Dish Piston Set, designed for optimal strength and durability. Crafted from premium 2618 alloy forgings, these pistons deliver exceptional performance under high-stress conditions. The forged construction ensures superior tensile strength, making them suitable for high-performance tuning and racing applications. Each piston features precisely machined ring lands and grooves, which enhance ring seal and promote more power output. The cam and barrel (skirt) profiles are engineered to generate substantial power while maintaining a gentle interface with the cylinder walls, contributing to engine longevity and efficiency.
Manley’s unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves are perfectly aligned and squared with the skirt. This precision manufacturing process guarantees consistent performance and fitment. The pistons come standard with chrome moly wrist pins, offering reliable durability, with optional upgrades to 9310 or Turbo Tuff/DLC alloys for even greater strength. These pistons are ideal for professional engine builders and tuners seeking a reliable, high-quality upgrade to improve engine performance and longevity.
The set is designed specifically for a bore size of 84.5mm and features a -10.5cc dish to optimize compression ratios for high-performance setups. The pistons are compatible with various aftermarket modifications and are a proven choice for enthusiasts looking to maximize power output while maintaining engine integrity. Please note that these pistons are not carb-approved and require carb acknowledgment, with air freight restrictions in place. Trust Manley’s reputation for quality and precision engineering to enhance your engine’s capabilities.
