Cosworth Stroker Kits


Increased displacement means increased performance. A Cosworth stroker kit is the perfect way to add power and torque to your high performance vehicle. Each kit includes select, matched motorsport grade components ensuring maximum performance and a key factor often overlooked; Reliability. Each kit features billet or forged steel, fully counter weighted crankshaft for smooth, high revving operation. The kit is finished with Cosworth forged steel connecting rods, forged pistons, and a complete set of Cosworth bearings. Each stroker kit is engineered to have the perfect bore to stroke ratio, yielding potentially big gains in torque while still allowing the engine to rotate and produce power in the higher rpm range. Add a set Cosworth CNC Ported Big Valve Cylinder heads and complete your stroked motor by providing maximum air flow to the stout bottom end.
