SRP 867-279591 Features:
SRP Professional pistons combine forged piston durability with modern performance technology for an extremely capable forged piston kit that doesn?t break the bank. Forged from 4032 aluminum, SPR Pro pistons experience minimal thermal expansion, making them perfect for a high-performance, reliable engine build from the track to the drag strip. All SRP Pro pistons include premium ring sets, wrist pins and locks. As with all JE Pistons product s, SRP pistons are made 100% in the USA.- < ul>< li> Forged in the USA using 4032 aluminum, yielding tensile strength and minimal thermal expansion < li> Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
"The most advanced piston package for your engine"
SRP Professional pistons 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. Additionally all Professional Series pistons include a skirt coating and JE Pro Seal Premium Piston Rings at no additional charge. The included ring set features 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 manufactured in the USA at the advanced JE/SRP Pistons manufacturing center. The piston designs were created using 3D computer modeling and tested for strength using Finite Element Analysis (FEA).
