Do they bolt to the newer 'torque control' slipper? I thought they were only good to fit the old style slipper?
You have to enlarge 3 of the small holes to 5mm to fit the revo spec slipper mounts. And you can either enlarge the center hole to 11mm to fit the stock bearing, or use a 5x10 bearing that is slightly oversize. I usually just file fit the spur to fit the 5x10 bearing.
