can only buy one locker or dual t-case?

[93toypu]

I am new. I have 93 toy ex cab 22re 4x4 with arb lift 1-2 inches and 33s I have CBI front bumper and need to build the rear but it is a CBI. I wanted to get some opinions about wether to save for new gears and a locker or go for dual t- case? I use the truck as a daily driver but wanted to slowly build it up.

Locker, ARB if it is a DD.

Seeing as you can get a spartan for under $300 I would start there and then save up for duals.

I think you can go farther with more control off road with duals than you can with stock t-case gears and a single locker, but a rear locker can be more affordable.  What kind of wheeling do you want to do?

I've always recommended a single 4.70 t-case because it's a bolt-in type of mod that doesn't require the floorboard and driveline mods where cost can be a bit of an unknown if you're not doing all of the work yourself.  The only downside is if you wheel in mud and need the higher range.

Assuming that you don't need the stock low range for speed (i.e. hill climbs, mud, etc.) and are satisfied with your street drivability, here's what I'd work towards:

(1) Single 4.70 t-case gears
(2) Ring & Pinion with a mechanic Detroit style locker in the rear (ultimate reliability)
(3) RCV front axles and hub gears
(4) Front Locker (Aussie)
(5) Dual ultimate

33s pushed me over the edge to needing new gears for the street in my 85, but you likely have a bit more power to work with.

Since you are new to wheeling, I would go with dual cases, throttle control at this stage is more important than traction.  I know this may seem counterintuitive, but you can always gain traction by stacking a rock or two(or more), which is a must have trail skill(either for you or those you wheel with), whereas you can only go so slow with a stock t-case and manual trans before you stall.  Not being able to slow your speed down due to stalling, often requires you ascend/descend obstacles faster than needed, which tends to leads to breakage, dual-cases help to reduce this issue.

Locker(selectable or auto), have the tendency to push you in a straight line, and as such need to be compensated for before you get to the line you want, or the obstacle in your way, something that is hard to do when you are still learning how to read the terrain and learn how to position your rig.  If you do go with regearing and a locker, then go with a selectable, as a selectable will allow you to wheel the trail with an open diff, and then be able to engage it only as a last resort, which if used sparingly will still allow you to learn how to read the terrain and find the right line. 

Having wheeled for about 14yrs before getting a locker(11yrs with) and 17yrs before dual cases(8 with), I find I use the ARB's about 10% of the time, and dual cases 60% or more.
