The parts supplier for my dealership said my shafts would be maxed out in height but i would be alright. Its the only worry i have. Most of my buddies drive lifted trucks and they said i could always have a machinist make a spacer for the axle yoke if it was too maxed out.

 

You may want to get some more opinions IMO. These are not like lifting trucks. Different animals. If I were some you I would spend more time on here before you go this route.

 

You can't extend the driveshaft with a spacer, that would just make the angles worse. You need a new driveshaft if you'll be doing much offroad. I would suggest a drag link flip, and gusset and sleeve the axle (at least). You'll want to regear with 37s as well, and need a reprogrammed with the regear. Going to 37s gets expensive...

On the lift I would just get the teraflex 4" and install it yourself. It's not that hard with simple hand tools and just get an alignment at a good shop.

Also, replace all the control arm bolts with northridge's grade 8 hardware kit. Have fun with the build.

 

I have a 2012 2 door auto with the 3.5 lift and 37s. Due to the cost of the regear I decided to get the chip. With the chip you notice a large difference In your RPM. I can still feel the gears changing late but that's because I'm auto. If you want to run the stock gears in manual you should be fine. But i strongly recommend the chip!!

 

What chip did you get?

 

Superchip Flash Cal. Very easy to use. And very cost efficient compared to a re-gear
