SRP Professional Series 4032 Alloy Forged Pistons
SRP Professional pistons combine forged piston durability with modern performance technology for extremely capable pistons and kits that won'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. Offered in a wide variety of engine applications in popular bore and stroke dimensions, select the ideal fit for your build.
Features:
* Forged using 4032 aluminum, yielding tensile strength and minimal thermal expansion
* Advanced Forged Side Relief (FSR) forging design increase strength
* High performance, low-friction skirt coating reduces wear and reduces operating noise while optimizing performance
* High-quality narrow wrist pins reduce weight, locks, and JE Pro Seal premium piston rings are included
* Ring set:
-- 1.2mm premium steel top ring
-- 1.5mm Napier (hooked face) second ring
-- 3.0mm standard tension oil ring
* Accumulator grooves help reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
* Strong and quiet
* Requires less initial piston-to-wall clearance and quieter at startup
