Rear diff tricks???
Howdy folks,well one thin leads to another! Im making steady progress towards the poor house and divorce on this 72 Chevy C-10 LWB. Before I install the new brake cylinders I thought I may as well see about axle seals,yoke seal(which is wet with oil)and cover gasket. My question is; Can these 12 bolt rear ends be made into a limited slip or positrac type rearend? Or do you have switchout the whole rear end for another type? I seem to remember a kit that installed and would lock both axles. Input? Ideas? Thanks you guys!

Re: Rear diff tricks???
The 12 bolt truck 8.875 axle has a pretty good aftermarket following as far as posi/locker selection goes . No need to swap the entire axle . The eaton posi seems to be well liked .

Yes the eaton posi works great, a little pricey for my blood.

Re: Rear diff tricks???
best "trick" i know of with rears is to have money and drop off at a shop for rebuild then pick it up in a day or so

Re: Rear diff tricks???
x2 on that - just tell them what ratio you want and what diff. Eatons are good, but kinda pricey, I had an Auburn 'High Performance' LSD in my '92 C1500 w/ 10 bolt and it worked great. I would recommend it, and the price is good too. I got mine through Jeg's, but had the rearend with new 3.73 gears professionally set up.

Re: Rear diff tricks???
I thought 12 bolt rear ends were positrac. My 69 has a 12 bolt , and it is a positrac.
