Should I weld the gears of my 10 bolt chevy rearend or invest in a spool to lock up the axels? I would have to take it to someone to have them welded but is that really strong enough?? Is there a spool for these? Where could I fine one?

Speedway Motors sell mini-spools for chevys, there about $90.00. I'm sure other retailers do as well. As for what route to take, someone with more knowledge will have to tackle that one.

I personnally like the mini spool in this case however I have ran both and it's very simple to weld them but they will develop some play with use

Well...... If you buy a spool you know its solid, it wont chip or flake, and your out of some $$$$$. If you weld, its cheap, easy, and can be repaired if it has a problem, just weld over it. I personnally prefer to save the money. I would also like to suggest to not weld the entire carrier solid, just the spider gears. You weld something like every third tooth, I cant remeber right now, and it allows the slack mention earlier. You want a little bit of slack. If you get hit in a tire and it has a little bit of give then you stand a better chance of not braking the axle. Just my opinion.

The last GM rear I welded for a guy took 14 welding Rods, and I top coated it with the MIG to seal in the slag. Welding rears is not a good place to start or practice your welding. Let a good welder do it or pay someone to do it, $20 bucks is a good donation..
Make sure you leave the spider gear shims in, you need this to maintain your c clip distance.
WELD IT SOLID. Dont leav it floating, Itll wear out the cross pin holes if you dont.
Take the time and do it right.. You'll never have any prolems.
One other thing on GM's make sure you start with the right carrier, if your using anything over 3.08 on an 8.5 youll need a different carrier, unless you have the special gears or a shim. Same with the 7.5s, Im not sure what the gear cut off is.
I would hate to see anyone wast the time to weld up the wrong carrier!!HEHEHEHE
Sun Screen anyone!

This topic brings up a question i've been wondering. My current car has a spool in the rear. Track rules say no spools, locked rears, etc. How do you detect a car has a spool unless you open up the rear? I'm gonna try and get by with it (i know others have, and i know they dont open the rears) but in case they find it and say no way, are they removable? And how much of a pain is that? Sorry for all the questions, but I dont know much about rears! tnx!

Does it say no spools, lockers, etc.? If they don't want you running any type of locked rearend whether welded or whatever then its easy to see. Whenever you run your heat race and the track is still wet in places they will see both tires spinning in the mud, throwing rooster tails. If its just that they dont want traction devices like a detroit locker or something like that then you shouldn't have a problem. Does this make since?

jack it up and spin the wheels? i've found that you can spot them pretty easy in the pits by watching the car in question take a corner.it will try and drag one tire .it's kinda hard to tell you what it looks like,but you will know it when you see it.as far welding the rear end ,i hate to disagree with widebody,but i go the fill the teeth in the spiders route,i find a little wiggling is a good thing

I agree with you all, use a 220 stick welder to make it as strong as possible if you weld it. You can weld them, its not that hard. just make sure there is plenty of weld, I always welded them tight and they develope slack anyway so you decide. And one last thing, chevy ten bolts are a dime a dozen in the junk yards so don't worry if you break one, surely you will be able to find another.
I have used welded rearends in our purestocks for many years and the worse thing to happen was the spider gears broke but were easily replaced and I have never done it before, the new ones are going strong.

I WELDED JUST THE SPIDERS ON ONE
REAREND AND HALFWAY THROUGH THE
SEASON IT BROKE LOOSE AND DID SOME
DAMAGE.
THE ONE I HAVE NOW I WELDED THE SPIDERS TOGETHER PLUS I WELDED THE SPIDERS
TO THE CARRIER AND HAVENT HAD ANY
PROBLEMS.
I WOULD HAVE USED THE SPOOL BUT IN
PURE STOCKS YOU HAVE TO CUT COST WERE
YOU CAN.

I run a 7.5 gm 10 bolt with a 3.08 gear, I'm thinking about going up to a 3.23. Will the carrier I use now work with the 3.23 gears? Or will I have to get another? If I do, how do I tell the difference between the two carriers? Thanks for any help.

O.K My 2 cents. Weld them with a mig welder all the way around the axle gears and weld the spiders to the axle gears. as far as detecting a spool all the tech guy has to do is stripe the tires in the same place on both sides while you sit in line then after the race he looks to see if the lines still line up.
