Pulley differences - 3222205 vs 3222220?

Can anyone tell me what the difference is between the 3222205 and 3222220 lower pulleys?



Both have the same tooth count. The 3222220 came on the '14-'15 models and the 3222205 came on the '13 model. My guess, they found a different manufacturer that would make them cheaper.



Also, does know what length of bolt I need to use either pulley on a steel driveshaft? Thanks.

Get ARP bolts for the QD pulleys. Yours will take an M10x1.25 40mm for the top pulley and M10x1.25 20mm for the bottom.

13 lower QD pully vs. 14-15: my understanding when I talked to Kurts Polaris (who makes the gear-down kit) is the shaft and splines were a slightly different size - they had the spline tolerance so tight on the gear-down kits that they had to manually file and fit them. I had both the 13 and 15 bottom gears at one point, and a very low mile 15 shaft, and they both fit well, and I took a video showing backlash on both and they were virtually identical. So either one should fit the axys. I sold both sets to guys with Axys sleds and I am sure I would have heard if they didn't fit well...
