Hello everyone, been offline for a while. been busy

anyways, i was looking at several modifications i would like to do to my 08 3500HD CC Dually.

1. Lift with larger tires. i only want to lift it about 4" so i was thinking of getting a 6ish inch lift and adjusting the t-bars till the CV joints where straight. then putting on larger tires. being a dually this task becomes harder. i like the look of 33"s but i dont want to go with something two skinny. then there is the problem with needing spacers. i was thinking of trying out 265/70/17s with spacers. not sure if 265s will be two small with a 4" lift. input here would be nice

2. built transmission. since i am in california Mike L is the only way to go. i had my 04 LB7 done by him and it hasn't ever let me down. i think i will stick with him. i put a transgo jr. kit in this transmission and it seems to be holding up great so far. i am probably running around 450-475HP right now. i dont really want to upgrade the transmission till this one starts crying uncle, which may or may not start shortly after mod #1 or 2

3. compound turbos. i so far have not found a kit that i like as i would like to keep the coolant tank and battery (if possible) in its stock location. i have seen some photos on the net of people that have done it and i think it may be possible with the LMM. i can weld good and have some tools, etc so i was thinking of just building my setup. the issue is finding all of the small odds and ends, fittings, flanges, etc and taking the truck off the road till i finish

my question is that since i can only afford to pay for one of these mods about once per year, what sequence would you do and any input or suggestions on them?

for any questions that may be asked. i do my own Efi Live tuning so i can dial in the mods myself. i am planing to limit my HP to about 600 so i can try and keep the engine together reasonably long. i don't do too much towing, maybe 8-10K every few month a couple hundred miles at the most. i will at the same time usually load the bed with 5-6K lbs while towing. so far the truck runs great like this.

alright fire away.

 

Personal bump

 

hey man go check this guy out DealsWheels if you decide on 1. he hooked me up with 6 315/75R16 MTs which is a 34.8 tall 11.2 wide and a lift and other stuff hes kinda sponsoring me and his prices are unbeatable man so i would do 1. then 2. then 3. get a 4" lift and then a set of 20" fuel dually wheels they are 8.75 wide look best imo with a 275/60R20 its a 35 tall 12.5 wide and looks great on duallys

 

Thanks i will check them out.

I was thinking of more like what Nor-Cal Nick did to his truck when he had stock rims. I think he used 295s. I dont want to go too big. I want to be able to tow heavy without struggling too much and sinking a lot of money into broken parts. I want a larger tire size that complaints the truck but can still take it to the drag strip or pulling events. 315s look great but start to loose on other departments

Here is some photos of Nor-Cal Nick's truck

 

quiet in here,

crickets chirp, chirp, chirp

 

So i put my ARB locker in Friday. Just finished plumbing it in and getting all of the electrical hooked up.

Got the free compressor with the deal. Wired that one in too. Now i have both the viair and ARB filling the tank. Dont know if i will keep them both but for now...

I didn't use the switchs from ARB. Instead i repurposed two factory buttons. Found on ebay a button setup that had buttons for some options my truck doesn't come with and used those. Now it looks stock and no one would even notice.

I tried it out last night on a section of my lawn where when trying to drive up it i have to use 4wd as it is slippery and the wheels just slip. I tried it out in 2wd and of course slipped when driving up the slight incline. Then pushed the button to engage the locker and it drove right up no problem.

Happy as can be.

Now i just need to put the front one in. I will likely wait until I do the lift and digging into the front already

Here are some pictures of the old G80 that never seemed to work and the buttons i rigged up












Tapped into the back to attach the wires and power the button lights

 

To touch on the Twin turbo subject, most twin turbo kits on the market will provide a different coolant tank and a battery relocation kit due to the tight quarters in the engine compartment.

 

thanks. that was a part that i am still thinking about. i have no problem moving the batteries. i was thinking of maybe moving the coolant tank to ware the driver side battery is now. hmm.

still trying to figure out how to keep my emissions junk still attached. grid heater, EGR, PCV, etc. they may be "broken" but still intact

i know some kits for the LML keep the emissions equipment in place so i think it should be possible with the LMM. its a California thing

i am just not too sure about spending 3 grand on a kit when i can get the S475 for less then $1000. the rest of the kit surly cant be more then $2k worth of parts. most if the parts on the list i think i can source and fabricate myself.

i am thinking of trying to build something like this




or maybe even this. of course not triple turbos but tucking it up in the wheel well.


if i cant make any of that happen then i may just bite the bullet and get their kit

 

hey did your truck come with a factory locker? 11.5 inch ring gear? if so i need one!!

 

Most duramaxs come with the G80 locker. Check your glove box sticker and see if it show G80. If so you have the locker. That doesn't mean it works, ha ha. Like mine it didn't seem to do a dam thing. I think the wrong fluid/additive was used so the clutchs couldn't engage.
