ACT Prolite Flywheel Nissan SR20DET

ACT XACT StreetLite Lightweight Flywheel for S13 S14 SR20DET. Weighing in about 14.1lbs, this low-inertia and lightweight flywheel is a big contender in performance and function. The one-piece design from hot forging chrome-moly steel, gives ultra fine centralized grain structure for superior strength and efficient uniform heat transfer. Each flywheel is made with precision and high tolerances using CAD and FEA (finite element analysis) methods to produce a flywheel that yields the best results to meet many legal racing standards such as SFI Specifications 1.1. The integral ring gear is part of the one-piece design to prevent any sort of separation during high RPM's and it allows more weight reduction at the outer area of the flywheel which provides very low inertia resistance. All flywheels are CNC machined with digital computer balancing for a super smooth operation and reliability.
