Eaton 913A481 Detroit Truetrac 8.5" 30 Spline Differential with 10 Bolt for GM

The media could not be loaded. Preforms great! Installed on a 1995 2 door tahoe stock 350 with 3.43 gears unfortunately I didn't shim it right with the yukon gears I have it paired with so it's noisey but it works amazing in the video there I drove up a wash out caused by previous rainfall and someone else actually got stuck there well I show that it gets stuck but once u pick the right line in only 2wd I was able to climb up that spot with no issues whatsoever ever that locker works amazing!

This thing just works and has no friction discs so it will last forever compared to a posi unit. I do sometimes hear the tires grabbing on tight turns on wet or dirt roads but nothing much. If you are having a hard time deciding on a locker for your GM truck I'd highly recommend this.

Easy to work with very nice customer service - Product as described 1967 GTO 8.5 rear 30 spline axels

Perfect replacement for broken g80-installed myself in driveway,be sure to get the correct new bearings and races and change the axle seals while you have it apart.Also bought 6 qts of gear lube (non synthetic) so I can change the oil again in about 500 miles,so far it’s as smooth as can be don’t even notice any difference with it,time will tell. I’ll update with any changes that may occur but from all the reviews I’ve found about it I haven’t seen to many negative ones.Well worth the money and no more broken spider gears.Edit- well it’s been almost 2 years and I couldn’t be more satisfied with how well this works, the traction is amazing and well worth every dime, if your reading this chances are you blew up your g80 too trust me this is way better you won’t be disappointed just buy it.

put this in my 01 tahoe to replace a G80 govlock diff; performs great

Perfect fit in my truck and now it runs like a dream! My factory differential was wore out and the back end of my truck used to get around on me way to easy. Now, I have to really try to get it around. I didn't mind it being so loose back there, but when my wife drove it, I was always nervous she'd get it sideways and now I have some peace of mind knowing that she's going to hit corners without spinning out. I highly recommend this thing for anyone. My only gripe is about the bearings. If you are like me and having someone else install this, let them buy the bearings. I bought what I thought was the right ones, they weren't and they were destroyed getting them off.

Good quality Good priceWorks way better than my G80 locker in my 2004 chevy avalanche 4x4Definitely noticed the difference between Detroit truetrac vs G80 locker no comparisonMost the time I never felt the G80 lock up when neededBut the Detroit truetrac locks up and you can feel it

Great upgrade to the factory posi.use the following race/bearing to make this work for this year of GM 10 bolt.Bearing number TMK-LM102949Race number TMK-LM102911No limited slip additive is needed.I was able to reuse my factory shims, I strongly recommend when doing this job to buy some additional shims just in case.It’s a bit on the pricy side of things, in this case you get what you pay for.
