I have ran 23 spline 833's for over 40 years mostly in racing applications and never heard of gears seizing on the shafts. I have broke input shafts, out put shafts and 3rd gear cluster & main gear. As power goes up you will find that the 3rd gear will push away from itself and boom, you got a gunk transmission, did that 3 times. Now run a Liberty pro shifted Doug Nash, I broke that to, shifting into 2nd with the wheels in the air puts allot of stress on 2nd gear, about $1300.00 worth :


it's ok to butt heads, just don't do it with a butthead
