400 SBC FT PRO KIT

SRP Professional pistons combine durability, technology, and performance. Forged from 4032 aluminum, they offer minimal thermal expansion, making them suitable for high-performance daily drivers or street/strip applications. All SRP Pro pistons include premium ring sets, wrist pins, and locks. JE pistons are designed, forged, and machined in-house. Features include full billet construction, EN plating, and purpose-designed coatings. These are advanced lightweight FSR forgings, up to 20% lighter than traditional equivalent pistons. High-silicon 4032 aluminum alloy allows for reduced piston-to-wall clearance and quiet operation. Accumulator grooves improve ring seal. Designed for normally aspirated or moderate forced induction/nitrous engine applications. Includes high-performance skirt coating and low-drag performance piston rings. Lightweight, low friction metric ring package includes a 1.2mm Carbon Steel top ring, 1.5mm Napier 2nd ring (for improved oil control), and a 3.0mm standard tension oil ring. Minimal filing required. High quality 2.250" pin further reduces reciprocating weight. Carbon steel wire locks included.
