- JE Professional Series Pistons
SRP Professional Pistons have professional racing characteristics, such as lightweight forged side relief (FSR) forgings, high-quality wrist pins, and CNC-machined ring grooves and skirts. In addition, every package includes JE Pro Seal Premium Piston Rings that feature a 1.2 premium steel top ring, 1.5mm Napier (hooked face) second ring, and 3.0mm standard tension oil ring. Every piston is designed and made in the USA at the advanced JE/SRP Pistons manufacturing center.

The development of SRP Professional took place over the course of an entire year. The piston designs were created using 3-D computer modeling and tested for strength using Finite Element Analysis (FEA). Several revisions were made to optimize the strength and weight before manufacturing began. Unlike other piston manufacturers, JE/SRP Pistons make billet pistons from solid pucks of aluminum for dyno testing in actual engines prior to approving the final forging designs.
