SRP professional pistons and rings include features used in professional racing, such as lightweight forged side relief (FSR) forgings, high-quality wrist pins, and precision CNC-machined ring grooves and skirts. In addition, every package includes JE Pro Seal premium piston rings. The included ring set features a 1.2 premium steel top ring, a 1.5mm Napier (hooked face) second ring, and a 3.0mm standard tension oil ring. Every SRP Professional piston is designed and manufactured in the USA at the advanced JE/SRP pistons manufacturing center.

Piston design benefits include:

* Advanced, lightweight FSR forging that eliminates stress concentrations for superior strength
* Up to 20 percent lighter than traditional equivalent
* High-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation
* Accumulator grooves for improved ring seal
* Designed for normally aspirated or moderate forced induction/nitrous applications
