Tight axles?
I'm running studs but like Hemi446 I don't use lock washers. Just red Loctite and torque them to 55 lb. ft. The heads of the studs are still close to the spreader bars (less than 1/8" clearance) but have never hit. Been running it that way for over 10,000 hard miles with no issues. Take the washers out and Loctite them and you should be good
