hey guys im curios to what the differences are (besides the smart *** remark, ones a gmc ones a chevy) i know they both have the 6.0 and the denali was available with rear steer, do they have the same transfer case and everything else like that? let me know!

 

LQ9 vs LQ4
quadcab vs crewcab
or vs quadcab w/ quad steering
4L65e vs 4L60e
both should have the nu-venture tranfer case.







ones a GMC and one is a chevy

 

01-04 denali was ext cab w/LQ4 w/quadrasteer
05-07 denali was crew cab w/LQ9 w/out quad

they should all have the 4L65E

 

what are the hp numbers for the lq9 and lq4, and didnt some have the borg warner or was that the yukon denalis only? is quad steer problematic?

 

After '02 I believe the SDs went to the Borg Warner case from the NV 149, which the SSS had throughout it's production. A good place to look up info on both would be www.denalitrucks.com and www.silveradoss.com.

 

not completely true...the c3 was NOT quadrasteer.

OK, here is the break down on the GMC's.
'01 C3 Ext. Cab LQ4 325/370, 4L60E-HD, 3.73's, NV149
'02-'03 Sierra Denali Ext. Cab Quadrasteer LQ4 325/370, 4L65E, 4.10's, NV149
'04 Sierra Denali Ext. Cab Quadraster LQ4 325/365, 4L65E, 4.10's, NV149
'05-'07 Classic Sierra Denali Crew Cab LQ9 345/380, 4L65E, 4.10's, NV149

Everyone seems to know how the SS came equiped.

 

so 05-07 denali was the same as an ss??

 

Except for being a crew cab, a hell of alot fancier on the inside and heavier, yes.

 

What bout when it 1st came out?
