The pistons in this kit are part of JE's FSR (Forged Structural Radial) series, which combines the benefits of forged pistons with the added strength and rigidity of a radial design. Each piston is forged from 2618-T6 aluminum alloy, ensuring maximum strength and durability. The radial shape of the piston skirt provides enhanced piston-to-wall contact, reducing friction and improving engine efficiency.

The piston crowns are engineered with a domed design, which allows for greater compression and improved combustion efficiency. The piston tops are also CNC machined to ensure precision and accuracy, allowing for a perfect fit in the engine cylinder.

The piston rings in this kit are made from high-quality ring materials, including a compression ring, two oil control rings, and a top ring. The rings are designed to minimize friction, improve sealing, and enhance oil control for optimal engine performance.

Additionally, the JE Pistons 379449 FSR Ultra piston kit includes wrist pins made from chrome molybdenum steel, which provide superior strength and durability. The piston pin bore is precision machined to ensure a perfect fit and minimize wear.

This piston kit also comes with a set of piston pins bushings, which are engineered from heat-treated steel and provide a snug fit to the piston pins, reducing lateral movement and improving engine stability.

In summary, the JE Pistons 379449 FSR Ultra piston kit is a high-performance upgrade for automotive enthusiasts. With its forged radial design, precision-machined components, and high-quality materials, this kit offers improved power output, efficiency, and durability for engines with a 92.00mm bore size.
