We was sent some axles to test 30 splines 4340 chromoly thru harden. 2 with cut splines an 2 with rolled splines all 4 from the same bar. The 2 with the cut splines broke at about 8,910 ft. lb. an 120* of twist, the 2 with the rolled splines broke at about 8,945 ft. lbs. and about 110* of twist. I thought this would be good tech to know. Of course you guys all know i like breaking stuff.
