Hello Gents, I was wanting some opinions on what to do next for mods. As of now I have a 13' ccsb z71 w/5.3. So far I have done Airraid MIT, BB Tune, ARH LT's and a Gibson Dual sport exhaust. I don't want to dig into the motor, truck only has 6k on the odometer. I'm toying with the idea of going from the 3.42's to 4.11's front and rear along with a truetrac diff. Right now my truck has the G80 locker, is it really a bad diff to give problems later down the road? Are there any other diffs you would suggest or leave the stock one in? If I am leaving any other options out, I would appreciate your input on my ideas or ideas of your own! Thanks!

 

Not many engine options if a cam is off the table. Maybe intake manifold or 1.8 roller rockers (would need LS6 valve springs too).

 

Your def off to a good start, gears would prob be the next thing depending on what you want to do with your truck. Being a z71 are you going to want to lift it or lower it? Reason I asked is because for normal street driving the stock gears and locker are ok but if you plan to race it or lift it def get some gears and a more dependable rear dif. I haven't had any issues with the G80 in my truck but most of the time I race or do anything like that I'm in 4hi so it doesn't put too much of a load on it. Ever considered a stall converter? I know a nice converter will make the driving experience pretty fun. After that besides swapping to a FAST LSXRT intake manifold your pretty much left with tearing into the motor or adding a supercharger/turbo.

 

Only plans I have later down the road when it comes time to buy new tires would be a leveling kit with 33's being the biggest I want to go. I use the truck as a DD and won't be racing it. I have thought about a stall but dunno if it would be that beneficial with the stock cam.. When my warranty does end, I will be looking into a cam along with the DOD delete. I def like the idea of 4.11's though for the get up and go factor!

 

check my public profile of my mods on my 2012. and you dont need ls6 springs to run 1.8 rockers. im running 13s with stock cam.

 

The stock springs are barely adequate with the stock cam. You really need to upgrade the springs if you install higher ratio lifters.

 

Make sure you definately know what size tire you wanna go with before selecting your gear ratio. Vise-Versa. If go with Motive's 4.11s. Great overall great gear ratio. Tru-Trac is also a good upgrade also, head springs and stall converter also. Just make sure everything is good enough for when you decide to do a cam swap that way you wont have to spend too much.

 

33s I would do 410 gears since its a six speed trans.
If it was a 4 speed trans 4:30s
As far as mods go I would do gears n Tru trac then a stall then dig into the motor last.

 

Thanks for all the replies gents along with the good info. I'll be posting up some pics of my truck as soon as I get finished up here soon hopefully.

 

In for pics.
