- Exacting Ring Lands and Grooves: Precision-machined ring lands and grooves improve ring seal, which enhances combustion efficiency and power output.
- Cam and Barrel Skirt Profiles: Carefully designed cam and barrel skirt profiles reduce friction and wear on cylinder walls while supporting increased power.
- Unique Fixturing Process: Manley’s proprietary fixturing allows skirt turning and ring groove machining in a single operation, ensuring perfect ring groove to skirt squareness for optimal piston performance.
- Dish Design: The dished piston crown is engineered to optimize combustion chamber volume and compression ratio for the specified engines.
- Proven Performance: Trusted by professional tuners and engine builders worldwide for reliable, high-performance builds.
Construction & Design:
These pistons are forged from 2618 aluminum alloy, known for its superior strength and thermal stability compared to standard cast pistons. The forging process enhances grain structure, resulting in pistons that withstand high cylinder pressures and temperatures common in performance and forced induction applications.
The cam and barrel skirt profiles are designed to minimize cylinder wall wear while maintaining tight clearances for improved power delivery. The moly skirt coating on select part numbers further reduces friction and wear, contributing to longer engine life and smoother operation.
Installation & Fitment:
The Manley 86mm STD Grade A Dish Pistons are direct fit replacements for the factory pistons in the following vehicles:
- 2017–2020 Toyota 86
- 2013–2020 Subaru BRZ
- 2013–2016 Scion FR-S
These pistons are designed to work seamlessly with the OEM engine components and require professional installation. No modifications to the engine block or connecting rods are typically necessary when upgrading to these pistons, but proper machine work and balancing are recommended to ensure optimal performance and reliability.
What's Included:
- Single Manley 86mm STD Grade A Dish Piston
- Chrome Moly wrist pin (standard)
