JE Pistons Subaru EJ255 EJ20 99.5mm Bore Right Side Forged Piston – Part Number 291059R

Description

Enhance your Subaru EJ255 engine with the JE Pistons 291059R, a high-performance forged piston designed specifically for racing and high-demand applications. Crafted from 2618 aluminum in the USA, this piston delivers exceptional tensile strength and durability, making it ideal for both street and track use. Its precise engineering ensures optimal performance and longevity, whether you’re navigating the drift track or pushing your vehicle on the drag strip. The inverted dome/dish design offers a compression ratio of 8.50:1, tailored for specific engine setups to maximize power output and efficiency. Constructed with JE’s proprietary Forged Side Relief (FSR) forging process, this piston reduces friction and power loss by minimizing skirt width, while a shorter wrist pin saves weight for improved responsiveness. The skirt coating (depending on application) further reduces friction and wear on piston skirts and cylinder walls, contributing to smoother operation and quieter engine performance. An accumulator groove helps manage combustion pressure, reducing ring flutter and ensuring a consistent seal for reliable power delivery. Each piston includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, providing a complete, ready-to-install solution. Built for durability and performance, this piston is an essential upgrade for enthusiasts seeking to maximize their Subaru EJ255 engine’s potential. Please note that this product requires acknowledgment of Prop 65 compliance and is not carb approved, making it suitable for professional installation and racing applications only.
