Tim240z Posted July 27, 2005 Share Posted July 27, 2005 For a solid rear, maybe chevy 10 or 12 bolt, maybe Ford 8.8 or 9? Can anyone say for sure? Quote Link to comment Share on other sites More sharing options...

Phyxius Posted July 27, 2005 Share Posted July 27, 2005 That doesn't really look like an LSD that I've ever seen. Maybe a locker? I've never seen a locker, though, so I don't really know.... Quote Link to comment Share on other sites More sharing options...
JMortensen Posted July 27, 2005 Share Posted July 27, 2005 That is a Eaton Gov-Lock, or as we used to call it at Randy's R&P, the Gov-Bomb. It uses a centrifugal weight to open the diff above 25 or 30 mph. At lower speeds it acts like an LSD. The problem is when you start burning out and get over the centrifugal release mph, then slow down. It tries to engage the clutches all at once and ends up looking like a grenade went off. Commonly available on GM trucks in the 8.5 10 bolt, not sure if they use it on the smaller 7.5 10 bolt. I think back when they put the 12 bolts in they used the other Eaton which also had problems back in the day. The new Eaton non-Gov Lock is actually really good. That one you have is not.

JMortensen Posted July 27, 2005 Share Posted July 27, 2005 Check this: http://www.drivetrain.com. Type in "govloc" in the search, then click the first result and look on the pic on the right side of the screen to see what happens when they go boom.

Mike C Posted July 28, 2005 Share Posted July 28, 2005 GM used the Eaton with 4 coil springs in the 12 bolt truck until 74-75 or so. Then that monster showed up... In the 12 bolt 'til '81 or so when they switched to 8.5 10 bolts. The 10 bolt uses reverse threads on the ring gear bolts FYI. The factory 8.5 10 bolt in cars like camaros/firebirds used a single flat spring instead of the coils. Quote Link to comment Share on other sites More sharing options...
Here comes trouble Posted July 28, 2005 Share Posted July 28, 2005 Sounds like great stopping power with a hydraulic brake lock from 60 to zero in 3 seconds Quote Link to comment Share on other sites More sharing options...
