Rick, the race shop I use, recomends more than 140 pounds. The spacer determines the clearance, not the foot pounds. I run heavy duty, costom stub axles with new bearings and races. The failures in back tend to be a twisted axle, a broken upright or a broken hub. I ran last weekend and the nuts are still tight, so maybe I am there. I'll run one more weekend and then pull it apart and inspect all of the parts. Scott
