What to do next...

Supercharger, locker and gears, or skid plates, bumpers and slides?

 

All of them.

 

Depends what you mostly do with your truck.

 

What he said. Do whichever mod will be most useful to you.

 

That's a mighty deep rabbit hole you are gonna jump into with that supercharger and locker and gears. Are you sure you are ready Alice (Ryan)??

 

I'm honestly leaning towards a rear locker and regearing. A supercharger is a lot of money for not much bang. I don't really want to weight my truck down with plates either.

 

What's the locker for? Rocks, snow, sand?
What size tires you want to run will determine regear size choice.

 

If you don't have skids I'd do that before a locker...you're much more likely to use skid plates and sliders than a locker.

 

Rock and sand mostly. I'm running a 32" now but considering a 33". I drive a lot of highway.

 

Then you want to do sliders and skids first. Protect the under belly and the rocker panels. Then worry about your gears and locker.
Regear for the big boots. 4.88 gears for 33”s and 5.29 gears for 35”s is the general rule.
Go gain some experience before you think of putting something on that can get you into real trouble fast.
