JE Pistons - Set of 4 Nissan KA24DE 89.5mm Bore 10.0.:1 Custom Pistons - Set of 4

If you're rebuilding the engine in your Nissan KA24DE for serious performance, a set of custom forged pistons is a critical component. These JE Pistons are built specifically for the KA24DE, offering a 10.0:1 compression ratio and a 89.5mm bore size. They are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is essential for handling the demands of performance applications.

JE Pistons incorporates several design features to improve durability and performance. 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 help control combustion gas pressure, leading to better ring seal and consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. This set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
