JE Pistons Nissan RB25DET 86.25mm Bore 0.827in Pin Dia 8.5:1 CR - Set of 6

If you're rebuilding the engine in your Nissan RB25DET for serious performance, a set of forged pistons like these from JE Pistons is a critical component. These pistons are built to handle the increased cylinder pressures and temperatures that come with a performance build, ensuring your engine can put down serious power reliably. They are designed specifically for the RB25DET engine, meaning they'll work with your existing setup for an optimized build.

JE Pistons uses a proprietary forged side relief (FSR) design, which helps reduce friction and skirt wear, contributing to both performance and longevity. They're made from 2618 aluminum, a strong material well-suited for high-demand applications. Depending on the specific application, these pistons may also feature a skirt coating to further reduce friction and noise, along with an accumulator groove to help maintain a consistent ring seal under high combustion pressures. This set includes the pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings, all manufactured 100% in the USA.

This set is for a 6-cylinder engine with a bore of 86.25mm and a compression ratio of 8.5:1. Please note that these pistons are not CARB approved and cannot be shipped to California.
