helty said:you're on the right track. 31 splines, new differential (auburn, eaton, FRPP,detroit locker, all depends on your application). you may also want to look into having the axle tubes and torque boxes welded while you're at it.
i wouldnt "lean" towards an eaton. they are breaking too. like you said, the safest way to go is a spool but you lose a good bit of drivability. I havent ever heard of anyone breaking a detroit locker drag racing, of course i dont know too many people with them, but two guys i know are pretty hardcore and have good luck with theirs.hognutz said:I would do 31 spline axels, new diff, rear cover that will preload the main caps, gear ratio of your choice.
If you will be launching on slicks or very sticky tires look into the welding the torque boxes.
as to what rear diff you will run this is up to you. I personally think a detroit locker is worthless. there are twice as much money as a spool and I could not make one snap over with 35" boggers. I also broke the damn thing. If i were doing that truck over it would of had a spool.
my .02 is drag race run a spool.
streat use run a strong limited slip or possible and e-locker. they are very expensive so I will not run one. I am aftraid of breaking a $900 diff. I have not completely decided on diff yet. Leaning towards eaton.

a few of the guys from md that broke eatons went to the trutrac. they didnt get a whole lot of passes on them but im sure if they start puking we will read about it come spring timehognutz said:yeah you might not break one drag racing. I did that mud bogging. boggers get quite a bit of traction and a truck is alot heavier. I was just trying to point out they are very positive and very expensive so IMO the spool is a better choice.
I like corners too much so I am going Limited slip.

theres a mach owner over on the mach registry that has 28 spline mosers and has been launching it i think on drag radials with a 125 shot for about a year now with no problemsBlueRuckus said:Do you guys think that some upgraded 28 spline axles and a rear end cover would provide some low end decent insurance for a car that sees the track occasionally? Maybe 2 to 3 times a year and on DRs.
im sure it could help. i see more guys snapping axles on drag radials then busting rear ends. i dont think you have to worry about a cover either. hell if you just want to do that, just scoop up peoples stock stuff in the classifieds for 100bucks for diff and axles and have backups ready to go in instead of paying 300+ for some 28spline axles and diff coverBlueRuckus said:Do you guys think that some upgraded 28 spline axles and a rear end cover would provide some low end decent insurance for a car that sees the track occasionally?
