ja03z Posted September 25, 2008 Report Share Posted September 25, 2008 I'm trying to find out what the differences are between a 4wd Z71 and the AWD SS. I have the earlier but owners manual talks about not going over 65 or 70 in 4wd, which I dont believe is the case with the SS. Wanted to see if it was a different transfer case or front end gearing? anyone know Oh this is my first post here I'm James Quote Link to comment Share on other sites More sharing options...
CoolBlueSS Posted September 25, 2008 Report Share Posted September 25, 2008 4WD you can select 2WD or 4WD. AWD is always on. No shifting. Quote Link to comment Share on other sites More sharing options...
ja03z Posted September 25, 2008 Author Report Share Posted September 25, 2008 I understand the acronyms but there is an obvious difference in the gearing at the diff or transfer case to cause such a limitation on my z71 as far as how fast it can drive in 4wd.

Rausche Posted September 25, 2008 Report Share Posted September 25, 2008 I understand the acronyms but there is an obvious difference in the gearing at the diff or transfer case to cause such a limitation on my z71 as far as how fast it can drive in 4wd. The AWD SS transfer case is different. It is built to be used at highway speeds. Also, I'm almost positive we have different driveshafts from the 4WD guys, and maybe even front diff (or maybe just the gearing is different?).

04CHASE Posted September 25, 2008 Report Share Posted September 25, 2008 4wd, has a different transfer case that uses a chain , it splits the power 50/50 frotn to rear in 4 wd. awd , has a viscous coupling transfer case it splits thw power 62% rear and 38% front. the 4wd is nice bcasue you can heat your rear tires and do burnouts, and some have reported to be able to switch into 2wd after a nice 4wd launch.

black00chev Posted September 26, 2008 Report Share Posted September 26, 2008 diesels do it all the time at the strip... some just leave it in 4x4 the whole time. of course im sure their cases are much stronger haha. Quote Link to comment Share on other sites More sharing options...
mike1booth Posted September 26, 2008 Report Share Posted September 26, 2008 awd is much better than 4x4 in the snow... Quote Link to comment Share on other sites More sharing options...

F1SSS Posted September 27, 2008 Report Share Posted September 27, 2008 awd is much better than 4x4 in the snow... after racing awd bmws in the snow here that are awd, and driving a 4x4 z71, the awd in the sss is superior to 4x4 imo. Quote Link to comment Share on other sites More sharing options...
