Traction Control Systems Offered?

[Beach77]

Coming from a 4Runner, looking at a Tahoe, curious what traction control systems these new Tahoe's have?

The 4Runner has 4H/4L, Down Hill Assist, Hill Assit, and std traction control, and A-Trac (where it will stop free spinning wheels and put the power to the wheels with grip).

The std Tahoe does not come with 4L, have to get the Z71 for that I believe - although I saw a post where it looks like someone ordered with from the factory in a std LT.

Besides std traction control, is there anything else these beasts offer to help you off road?

Thanks!

My Denali has 2WD, 4H, 4L, Auto/AWD. Traction control/ESP, hill start assist, grade braking (transmission braking).

I assume any Tahoe with max trailoring or the 6.2 would have all of these but not 100% sure.

I really like the A-Trac feature of the 4Runner - curious if the Tahoe has anything like that or if it has the option for a rear/center locking diff?

 

[Beach77]

Did some digging, looks like a locking rear diff is standard on these - low speed transfer case is optional based on the package(s) you have.

The AWD Denali's will have an open diff, but the 4wd Tahoe should be posi. Look for RPO code G80 in the glove box, that's a locker.

I wish my Denali had the option of being 2 wheel drive. I miss the good old days of just rear wheel drive in the snow.

Huh? My Denali can be 2wd. Are there some that can't be?? Turn of ESP/Traction control and it's a donut king in the snow!

I have a 2004. It's full time 4WD

Ah ok. Maybe that's what the other guy meant too...or maybe some denalis are just have 2wd and awd options.

Yeah the GMT800 package Denali was never offered with 2WD, or with selectable 4WD transfer case. Only AWD as is my 2006. I do miss being able to turn it off in the summer when I don't need it. But it gives my xl nice handling characteristics especially up here in the winding mountain roads where I live. The latest gen K2XX Denali was offered with a selectable transfer case.

Crazy. My 2010 tahoe had awd, 4hi/lo and 2wd. Wonder why the Denali didn't offer that. Weird.

I believe the gmt900 Denali was offered in 2WD and AWD. Not sure what GMs thinking was on that. Haha.

Yeah, even the basic Tahoe transfer case had awd, 2wd and 4wd.

The upgraded tahoe transfer case added 4hi/lo.

I believe all Tahoe\Suburbans have a limited slip rear- diff, and my Z71 leaves two equal ruts when climbing steep gravel\ grass ascents - so it does work. When you engage 4Lo, it automatically disengages traction control and all of the "driving aids". Pure old school 4WD, and a very different experience from our 2008 Range Rover, which has many electronic traction gizmos to get you to the top of the hill.

I know Toyota products have vastly improved, but my number one complaint with our prior 2003 GX470 is that the traction control would not allow any wheels to spin. Hence, if all four wheels\tires did not have enough traction, the GX was dead in the water. The Z71 will get up hills on our property that the GX could not or I was afraid to attempt. I have not tried the new Toyota crawl control, so I imagine this issue is in the past. But, the traction control issue was a big reason that i did not get a Sequoia.
