I've heard I could save a lot of weight by having the bull gears machined. My question is how much weight? How much can you safely take off? Is it worth the expense to do this?
Thanks for the good information I appreciate that but I have a few more questions. Do you feel lightened gears would hold up to 6500lbs with 24.5s or am I asking for trouble? Also maybe this is a really dumb question but is there any performance gains by reducing rotating mass?
No dumb questions. They would hold up fine as long as it is a one piece gear. (Not a gear with a cast center and teeth rivited on). Have done bull gears for 8000lb diesel supers. Any time you can reduse rotating mass you are going free up some rpm to the tires. Would you notice a difference? I don't think enough to run a higher gear. If you have any other questions feel free to call. Nick
Some can be lost on a 560 bull gear by drilling holes between the rivets. I've never done a set because I'm not sure it would be worth it. Maybe someone has them is a llss or a lss but I wouldn't run them in anything over antique type stuff.
