My Detroit was a ten bolt and the Detroit was a 12 bolt so I got stuck with it but I would recommend it for Chevy or GM back diffs with 10 bolts

It is a 2L RWD pickup truck. As soon as I installed this differential on my RWD truck, I realized how much better it handled Buffalo's snowy roads. As of right now, I have not had any snow, so I will have to update this review once we have a lot more snow, but my driving experience has already been transformed. Whenever I accelerated around a corner or pulled out into traffic, I would lose traction with the open differential because the back end of my truck would 'skip'. This time, the vehicle keeps traction throughout the turn, and you can hear the differential do its work as one tire slips, and then is caught by the other. Tires usually make a continuous, squealing sound, but this one makes a repetitive chirping sound instead. As for acceleration from a dead stop in a straight line, I have yet to test this in the snow. I will update once I've done so. Having high expectations is very important to me. As an aside, clamping calipers and snap ring pliers are needed along with the usual automotive tools in order to install this.
This is a major improvement over my stock open DIF. Having taken a while to install, I can honestly say that it's worth the wait. In my 1991 Camaro RS, there is a 400 small block engine putting out 260hp, 410lbs of torque, and 366 cubic inches of displacement. There are 73 gears on the locker, so it's not a problem making that much torque, hooking up great with drag radials, as well as doing easy burnouts. It also corners well and does not make any loud sounds like other lockers do. It's a 10/10 locker and I'd definitely recommend it!.
The open diff is much better than the stock diff. So far, the material seems to be much stronger, although I haven't actually tested No problem if you need to make tight turns. A transmission with automatic transmission makes a slightly more distinctive clunk sound when you reverse direction.
