After initially installing the spacer I went to spin the wheels. Two studs broke due to the crossed threads. I named the axle and gear G2. Steve from G2 stated that they don't have bolts, you have to replace the whole part. Check out the others from Spidertrax who have replacement bolts from the Spidertrax website. By the way. Rockfitters also contacted their G2 representative. They said the studs will not be sold. A question of responsibility. So buy Spidertrax again. Rockfitters service was great. My request was dealt with in a timely and friendly manner. If you're looking for great service, Rockfitters is fantastic.
