JE Pistons NIS QR25 10.5 89MKIT Set of 4 Pistons

If you're rebuilding the engine for your Nissan QR25DE and looking for serious performance, a set of forged pistons like these from JE Pistons is a solid choice. These aren't your average cast pistons; they're built from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons has been in the forged piston game for over 75 years, and they engineer these specifically for each engine and application to give you the best balance of durability and performance.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and skirt width, which not only saves weight but also helps reduce power loss. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating to further reduce friction and noise, making for a smoother running engine. Everything is forged and machined right here in the USA.

This kit comes complete with everything you need to get your engine back together: four pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Just remember, these pistons are designed for high-performance builds and are not CARB approved, so they cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
