JE Forged Piston Set - 20v 5-cyl 2.5 - Mk5 Rabbit / Jetta - 83mm / 11:1 Compression
These are a set of high-compression NA pistons for MK5 2.5L Engines. They will work with stock rods but it is recommended to use a set of H beam IE or Pauter rods with them. They are made by JE pistons and are the highest quality pistons you can get for extreme use. They come complete with rings. wrist pins, and wire locks. This set yields 11:1 CR and is a .5mm overbore ensuring proper piston to wall clearance. Drop ins are available from JE, but in our experience not recommended. For drop-in pistons Wiseco is a better option.
JE pistons are a great upgrade for someone looking to build a stout, reliable engine. They have 20mm wrist pins so they will require a set of rods with 20mm pins to match. They feature JE's 2618 alloy which is stronger then most other pistons made from 4032, and are specifically engineered for extreme applications. Dish requires no deburring or preparation.
Optional Piston Upgrades
JE Tuff Skirt coating upgrade
JE's race-bred Tuff Skirt coating is self-lubricating and provides improved anti-friction and reduced wear. This coating is applied to the piston skirt designed to increase piston life and withstand many different types of endurance racing. Coating upgrades are non-stock and manufactured by order, all coatings have a 2-3 week lead time.
JE thermal barrier crown coating upgrade
The thermal barrier crown coating is applied to the piston dome, designed to reflect heat into the combustion chamber. This increases exhaust gas velocity, greatly improves scavenging potential, and extends piston life by decreasing the rate of thermal transfer. Coating upgrades are non-stock and manufactured by order, all coatings have a 4-6 week lead time.
Please note that these coatings are not free. We will contact you with the latest pricing before finalizing your order.
