JE Pistons COSWORTH N5B 93.5mm Bore 8:1 KIT Set of 4 Pistons

If you're rebuilding the engine in your Cosworth N5B for serious performance, a set of forged pistons is a critical component. These JE Pistons are built to handle the stresses of high-output applications, offering a significant upgrade over stock cast pistons. They're designed with a 93.5mm bore and an 8:1 compression ratio, making them suitable for boosted or high-performance naturally aspirated builds where durability is key.

JE Pistons uses 2618 aluminum, a well-built material known for its high tensile strength, which is essential for pistons operating under extreme pressure and heat. The proprietary Forged Side Relief (FSR) design helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to improve ring seal and reduce flutter, and a skirt coating to further reduce friction and noise while minimizing wear on the cylinder walls. Every set is forged and machined 100% in the USA, ensuring a high standard of manufacturing.

This kit includes everything you need to get your engine rebuilt: four forged pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. These are a solid option for anyone looking to build a robust and powerful engine that can withstand demanding use.
