I put a T-5 in my last 235 powered 53 1/2 ton and loved it. I now am building a 51 1 ton and seeing how the open driveshaft lends itself easily to the swap im going to do it. I used the tire,gear calculator and came up with 2470RPM @ 60mph with 5.13:1 gears in OD. Most of us dont haul any real loads with our trucks so do you think it will hold up under normal use? There cant be that much strain on the driveline with the multiplcation of 5.13:1 gears. What you guys think, has anyone else done it?
