Hello everyone. I just purchased a 2015 Suburban LS 4x4. My questions is how do you put it in 4x4 low? My switch does not have the option like the others I have seen or like the manual states. Also does anyone have any experience with a front leveling kit and if so what are the Pros/Cons.

Thanks

Here is my switch



No 4 low option.

 

It might be automatic as to keep people from putting it in low. 50 years I've NEVER used 4wd low

 

you can't put it in low. the tcase is a one speed tcase. there is no low option.

if you like the look of a 1.5" or so raise or want slightly bigger tires go for it.
you will need an alignment afterwards.

ebcm recalibration for speedo correction if you change the tire size.

 

I'm guessing GM realized that 99.5% of drivers never used 4-low. Thus decided to save weight/cost/etc. by omitting it.
I've used it exactly 2x in 100,000 miles. Once I took a turn where my front passenger tire went into a ditch and the truck was riding frame, while towing a 6500 lb trailer down a hill. (so I had to use 4 low to reverse 5')... worked fine.

Other time was towing my mower out of a ditch in the yard. (damn hills).

Both times, 4-high might have worked, but w/the trailer I was happy to have it...

 

As others stated, you have a one-speed transfer case and no 4-lo.

I'm not a big fan of the leveling kits. It puts extra stress on your front CV joints and will likely cause premature failure. Is that really worth it for a "look?"

I use 4-Lo quite a bit, but that's because I tend to take my Burbs places that a lot of other people don't. My best use of it was when I pulled a 30-ton garbage truck out of a ditch.

 

Thanks everyone for the input. I have had 4x4 my entire life and maybe used it once or twice. No big deal just wondering why the booked showed it but no option on the switch.

 

If by book, you mean the sales brochure, it lists a two-speed transfer case as an option. I think that started around 2009 or 2010.

 

the owners manual is generic showing all build options.

 

I use 4WD-lo frequently, not so much OTR, but when moving my TT around. My Burb is so powerful in Lo, that I hardly realize there's a large Trailer back there.
