Extended axle bolts in Stainless Steel for GT meant for mounting superfluxes to GT rails. These extend deeper than the stock bolts to get a better hold and less chance of looseing or damaging the threads in your superflux motor. Highly recomended if you ride hard! These Stainless steel bolts wont rust or break, but they will deform if you use an impact gun, so make sure to hand tighten only during install and removal!
