JE Pistons Sport Compact/European Pistons

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for European, import, and sport compact applications. Engineered, forged and machined, JE Pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. JE Pistons sport compact/European pistons are engineered for extreme applications, up to and including professional competition. In this environment, the higher compression ratios, highest boost, or heavy nitrous usage necessitate the higher tensile strength of 2618 aluminum alloy. Their domed or dished tops require no deburring or preparation and feature smooth-flowing radii for excellent flame travel. High-quality wrist pins, locks, and JE Pro Seal premium piston rings are included. JE Pistons' performance has been proven in victory lane time and time again. Available individually and in sets, equip your engine with the best in forged pistons. Features: * Designed specifically for each engine and use application to provide optimized performance durability * Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin * Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise * Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power

BoostLine Connecting Rods

BoostLine connecting rods are designed specifically for demanding turbocharged, supercharged, and big nitrous applications. The patented, 3-pocket body forged from premium 4340 steel incorporates the best features of both the H-beam (mass/weight) and I-beam (strength) designs. This provides 60 percent more bending strength compared to common H-beam rods. Each piece is heat-treated, shot-peened, and fitted with ARP-2000 cap screws (strong, malleable, and 220,000 psi rating) before final finish machining.
