These are the gears off of my 07 Sierra. GM 8.25 front / GM 8.5 rear
Truck has about 60k and they work flawlessly.
I'm switching to 4.56 gears.
This is would be great for a 6 speed with 3.08s or 3.23s.
I'm asking 260 shipped OBO to the lower 48. Shipping isn't cheap for these so take that into consideration.
