The Cosworth fully counterweighted 94mm stroker crankshaft is the perfect way to add torque and engine response to your 4G63 (7 bolt).

Machined from a solid billet of EN40B steel, our fully counter weighted crankshaft is the ideal stroke for increasing torque while not sacrificing high rpm performance.

Combine with our special stroker piston to maintain correct rod length and ratio (PA2701.100).
