I've heard that with a 10 bolt rear end putting drag radials on with break the rear end. Is this true?

Would it be bad to put drag radials on my car?

 

Unless you started doing 5K rpm clutch dumps, I doubt you would break anything with a stock engine. But you never know... people have broken the 10-bolts on street tires. Others manage to run 10's on the stock rear. It's a crap shoot...

 

I run nitto drags... So does basically the entire tampa fbody and mustang club here. Only 2 have had to replace things that have broken. 1 guy has 700wrhp and the other does those 5k clutch dumps all the time. They both still run nittos and the 10bolt.

I run a TA girdle to be on the safer side, and rarely do heavy clutch dumps.

 

I'm running Nitto's on my M6/10 bolt. No breakage yet, but I haven't been out with the head/cam package either.

 

Fred put it best, it's really a crap shoot with dr's on a stock rear. I've made around 50 passes with either Nitto's or BRG dr's on my stock 10 bolt so far with no problems at all. I have installed 4:10's though, along with using a solid pinion spacer, a bearing stud kit, and a reinforcing cover with the preload studs. I made a few passes on street tires on the completely stock rear without problems either. I now run 255 BFG dr's at the track and 275 Nitto's on the street, and I'm not easy on them or the rear I think the biggest problem with the 10 bolt is the pinion crush sleeve, after a lot of abuse the pinion can get out of alignment with the ring gear causing the gears to break.

This should probably be in the drivetrain section

 

Is there anyway to make the 10 bolt stronger?

 

I don't think I have ever quoted myself, but:

Those are a few ways to make the 10 bolt stronger. (except the 4:10's)
