3.73 Gear Option/Build & Price

[c0boy]

I just noticed this option on the build and price.  It requires the 3.0 TD and packages a whole bunch of stuff (Tonneau cover, chrome steps, 275/65/18 Duratracs) which besides the tires I wouldn't want.  I'm wondering if this is available another way.  Please shed some light if you have some info.  Thanks

That’s the “diesel off-road performance package“.

 

It’s also listed as available in the order guide with the new “Custom Max Trailering Package“ on the 5.3 6 speed powertrain, but not shown on the build and price. 3.73 is not available on anything other than those two.

It's also only available on LT and RST trims (which are non-lifted).

Trailer tow rating and GVWR don't seem to be listed either.

The package doesn't currently show as available on Sierra.

Would that be the 9.5” rear axle?
