JE Pistons Professional Series Flat Top Pistons SB-Chevy 400
532-309948

Specifications:
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.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
