1977 K10 3/4 ton axles
Worked great on a 1977 K10 with Dana 44 8 lug. Have to roll forward/backward slightly to fully lock, but that's fairly normal with these old axles it seems, so it's fine.

easy replacement and correct fit, high quality part!
I have had a number of trucks with these hubs on them, and they have never given me any issues. These are high quality parts with a classic design. The heavy brass dials feel solid, especially compared to old weathered plastic. The brass gets a nice patina as they age also. Warn makes a "hub fuse" that can be easily added to these also- the idea being that the cheap and easily replaceable fuse will fail before your drive line, u-joints, or axle shafts. These took less than 40 minutes to install with very basic tools- if you don't have a 7/64" allen wrench you will need one of those also.

Great product but not what came in my box...
The Warn 20990 locking hubs work great, had them for years on my LJ. However, this order must have been sabotaged by a previous buyer - I'm guessing they bought a good set here, put their knock-off take-offs back in the new packaging and sent them back as a return. Somehow, this was missed by the return process, restock and then resold to me. Disappointing that someone would do this and game the system. There was not an option to have them replaced, just a refund but I'm happy with that.

Good bang for buck
Fit great on my gm 10 bolt. 86 k5 blazer, couldnt have been happier with installation, had to remove one side to make adjustments and the outer snap ring can be tricky to get a hold of but once you do its easy! Other than that small inconvenience of removal they are good looking and bolts up easily!
