The present invention relates to a torsionally compliant sprocket system which absorbs crankshaft torsional vibrations and minimizes their transfer to other components in the engine system. In particular, the present invention includes a sprocket formed with an elastomeric member located between hub and rim portions. The hub has splines which cooperatively engage with keyways formed in the rim portion through the elastomeric member. A method of forming the compliant sprocket includes forming the hub and rim portions and injection molding an elastomeric material into a gap between the hub and rim portions. While in the mold, heat is applied to the sprocket assembly. The elastomeric member is thus vulcanized in place, creating a one-piece compliant sprocket.
