New here so bear with me... How do you lock a stock GM rear end?

they also sell aluminum or steel spider gear locks too. They replace the driven spider gears. They are essentially just machined blocks that fit in there really tight so it locks the rear end. They sell for under $30 a pair, and you wont ruin your carrier with them unlike welding the spiders together.

I race at two tracks, one I can lock it and one I cant. I had a freind of mine weld all the teeth on the driven spiders excpet the three that mate to the axle spiders. This locks it really tight, and i can lock and unlock the rear end in under 15 minutes. (It takes me longer to get fluid back in the rear end then it does to do everythng else)

Where can I get the blocks you spoke of? I raced back in the 70's, but I drove and didn't do much working on the car. Now my son wants to race so I'm racking my brain on how to build/set-up a car for him. "FUN"!!!
Thanks for the advice.

I saw them at my local race parts supplier. I have only seen them, and have heard they work quite well, but I dont know who makes them. Since I dont need them, I never really looked at them really close. I do know they are available though.

If there is a store close by you that you can get different types of dirt racing equipment, ask someone there. If they dont have them on hand, they surely could find out who makes them and get you a set.

good luck

I used to weld them up also. But since I went to the coleman mini spool I like it. I would only buy the coleman as the "other" brand (black one) is of poor quality. Also if you are really flush with cash Coleman now makes a full spool for the metric rear.

I have heard of using brass shims in the spiders. They transfer heat and lock the rearend, then when you get teched they will cool down a bit and unlock the rearend.

Any one have luck with this? I have an open rear end rule but I know my competitors are doing this.
