SRP Pro Pistons, SBC 372, Bore 4.125, Stroke 3.480/ 3.500, Rod Length 6.125, Dome +4cc, 417 Grams, Set of 8. Small Block Chevy 350/ 400 SRP Professional pistons are the most advanced lightweight FSR forging that offers superior strength. SRP pistons are up to 20% lighter than traditional equivalent pistons. 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 engine applications. SRP professional pistons come standard with high-performance skirt coating and low drag performance piston rings. Lightweight, low friction metric ring package included: 1.2mm Carbon Steel top ring, 1.5mm Napier 2nd ring, 3.0mm standard tension oil ring. Napier 2nd ring for improved oil control. Minimal filing required Pins and Locks. High quality 2.250" pin further reduces reciprocating weight. Carbon steel wire locks included. FSR (Forged Side Relief) forging designs feature a reduced skirt width and shorter wrist pin when compared to traditional “full round” style forgings. The narrow skirt helps minimize piston contact with the cylinder wall that can cause friction and power loss while the shortened wrist pins reduces the overall weight. Some FSR forgings feature internal and external bracing to provide a more rigid construction while minimizing overall weight. With thousands of race miles logged in the most demanding applications like NASCAR, NHRA Pro Stock and Indy Car, these pistons provide the ultimate combination of low-friction, lightweight design with increased stability and strength.
