I have seen a few dmax and hd's with smaller driveshafts, is a larger one a factory option?

The lb7's have a steel driveshaft, and the lly's and newer have an aluminum driveshaft, which is bigger than the lb7's.

the aluminum shafts are 5" and .080" thick.

i have an lb7 and it is aluminum drive shaft,never heard of steel shaft on the d-max.

Dunno, mine is steel. I wish I had an aluminum shaft so i wouldn't have to worry about it rusting on me. Every lb7 around my area has a steel shaft.

crew cab long box have steel two piece drive shafts, aluminum come on all crew cab short box or shorter trucks.

Yep....Got the steel under my truck.

RC LBZ with a steel.

I forgot the regular cabs also have the steel shafts.

my ccsb has a steel shaft.......also a ZF-6 though

mine is steel....ecsb

03 EC LB Dually = Aluminum

08 RC LB = Steel

.

'06 LBZ ECLB- Aluminum

easy answer: some do and some dont! LOL :D

'03 ECLB aluminum...

Switching my 2008 OEM 5" x .080" aluminum drive shaft to a Danville 6" x .125" (1/8" wall) to prevent any possible failures while launching across painted crosswalks or drains (which cause the tires to slip and then instantly grab on the other side). Plus, the Danville is not necked down at the forward drive end either (6" diameter along the entire length).

Don't want any flailing driveshaft tubes beating the underside of MY truck!!!

Only problem is that they're $850 :eek::eek::eek:

i wonder if its a "factory born" thing. As in i wonder if it has to do with the state and factory the truck came from. I have no idea, just an idea??

'04 ECSB = Steel

But it's also an 8.1L. :D

Mine has a 2 piece steel shaft

My 03 has the Aluminum, and it has the LB7 and it has a EGR also!!!!!!!!

Wish the EGR was not there.......

The type of drive shaft you have is determined by your wheel base.

Your both right, the duramax trucks might be %100 specific to wheel base, but i have noticed that the steel or aluminum tends to vary by plant of assembly as a general rule for GM trucks.

why not just have someone make you a 4" steel one for , oh, i dunno $350 max? If your that worried about spitting out a driveshaft, have a driveshaft loop built. $850 is ALOT of coin for a light truck driveshaft.

My 2wd CCSB has the 3 mile long 2-piece steel driveshaft.

my 6.0 ECSB has a steel driveshaft

my 05 duramax CCSB has a aluminum one and so did my 02 ECSB 6.0

I have an aluminum on mine

wifes 01 ccsb-steel, my 02 ccsb alum, dad's 02 ccsb-steel go figure.

I wonder if it has to do with the plant. The 11th digit of the VIN tells the plant code (at least on 2003s): http://service.gm.com/dealerworld/vincards/
2003 GMC CCSB
Aluminum driveshaft
Flint, MI plant (VIN F)
