8 3/4 gear change
I have an 8 3/4 in my Satellite that was a 2.94 pegger. I just bought a sure grip chunk with 3.55's. Easy swap. Just get a gasket and the appropriate lube and limited slip additive. You can do it yourself, you might want to use a jack if you can't lift it into place. If you want to change the gears in your chunk keeping it a pegger, you might want some professional help setting that up.
