Yes, you weld the spider gears together and it locks it up solidly

One notr tho, I did that several years ago and one day on the way home from the Alton, Il dragstrip they broke and I had to leave my car along side of the road---when I got back, the dual quads were missing

You can buy what is known as a mini-spool to replace the spiders pretty reasonable--

WELDING Rear Diff.

Thanks for the reply's... I only drive this thing a few time a year and when I do.. watch out for the smoke. I am tired of replacing the RR tire and need to give explicite instructions to my brother where to weld. Dumb I am, but also determined and a little excited. If anyone can give me step by step instructions to complete this it would be much appreciated...

thanks!

well you can take spider gears out fill up two teeth on the gear top at 12:00 and 6:00 do both this way and up them back in? well i think thats is how it was done that been over 25 years ago it will let them turn abit but not to much all this stuff is very hard on the rear end and parts your much better to buy a limited slip

Just buy a mini-spool, when it breaks you need another mini-spool. When the welded spiders break, you need a brand new third member. The mini-spools only cost about $40.00, a used 3rd member is about $250.00....

I agree, get the mini spool

You'll definitely be sorry if you weld the spiders

yep and if a C clip axle if the rear end axle brakes you need a new truck or just a box side if lucky**)

We usedta weld 'em in our round-track stock car, and you had to weld EVERYTHING into a lump or it'd break up after a few races. And yes, then you need a whole rear end ,cause they won't come apart again!
