Hi i have a set of shafts from a 2004 firecat that are aftermarket/custom made . These shafts are steel . The jackshaft is a 15 spline and setup for a splined brake rotor that i have and is a one peice hub/wave rotor . The drive axle is a steel 1" 1/4 shaft with 9 tooth drivers and is hollow with 16 splines . I have a 20 tooth top gear and a 46 tooth bottom gear with the chain that will go with the shafts . These shafts were in my sled when i bought it . The guy i bought the sled from raced for cat so i dont know who made the shafts . For sale or will trade for a good used set of fox floats with pump for my 04 firecat . Thank You
