SASed time for gears and dual t cases...help

ok so i am done with my SAS in 89 std cab short bed 22re i have 5" marlin springs on 35s i still have the stock gears. i want to do dual T's but i don t know if the chain drive was an option on my truck and i don t feel like tearing it apart to find out.

its a base model truck 5 speed bench seat. no rear slider or A/C. power steering is the only thing power about it right now.

i am also having trouble deciding on 4.88s or 5.29s i do drive the highway alot but i live in town now so i don t know what to do.( anyone know where to get a speedo calibrator?

my order for more power was just sent to LCE i got the header, intake, cam, and bigger throttle body.

anything you guys can help me with would be awesome i need to get back on the trail.

35"+ size tires and you'll want 5.29's for sure. it puts your back to "stock power"

Regear and lockers at the same time to save labor involved.

5.29s with 35s or bigger, but I have 4.88s with 39.5 Iroks and it is fine for a trail rig

You are going to have to do d-shaft work anyway after your SAS so why not do duals now and d-shaft work once?

Sliders, armor, winch

All kinds of ways to spend your money.

What have you done besides the SAS? Rear lift? Longfields? Some more details would be helpful.

And pics...or it didn't happen.

Your truck has a gear driven transfer case, as for gears, its really up to you, im running 37'' tires and 4.88 gears on my 86 4Runner.

your gear driven.

5.29's, and either duals, or 4.7 single case.

they're POS humvees that weigh a load but will prove their worth when ur getting fired at. Ive talked with some navy guys who drive humvees... 2" thick steel plating all around, like 2-3" thick bullet proof glass, and enough room in the back for a crapload of redbull and a large stereo. Just dont go serious offroading in em

I can help you out if you are looking for a professional 529 gear install. So many horror stories out there about gear shops that screw up the gears.

PS---I agree on the 529 ratio for that tire.

the dual cases u'll need for the rear case an 84 or 85 top loading shifter and fork at least, a 23 spline turbo t-case input shaft would be nice but not necessary since you're keeping everything relatively mild. a custom crossmember to clear the front driveshaft. I just notched plated and gusseted my factory one for now. I built my own driveshafts. you'll need the non tapered style found in most older 84 to 88? regular cab trucks rear shafts and the cv out of your front. just cut the driveshaft 3 or 4 inches back from the weld near the u joint yoke on both rears. scrap the one or save for a spare. do the same with your front cv. take them to a machine shop and have them lathe the weld till the tubbing comes off. then beat those ends into whats left of the rear driveshaft once you cut them to length. make sure the u joint caps line up at either ends of the driveshaft when beating them on. reweld the ends on. I don't even worry about ballancing anymore and don't even notice the difference but some guys drill a hole and dump 1 oz of tranny fluid in to ballance. Its much cheaper than buying custom ones. I lathe my own so not sure how much You'd get raped for that. the v6 trannys have a 23 spline output and different mounting patern so that won't work with a 4 cyl or turbo gear driven case

Yeah I agree. According to my gps, my speedo shows 4mph faster than I'm actually going with my 35s, 5.29s, and a g52 tranny.

I'd definitely go with duals over a single with the 4.7 crawl gear. Ideally one with the 2.3 and one with 4.7 for selectability. It sucks trying get around on a trail when 1:1 is too high and 4.7 is too low. Then get to the obstacle and drop it down to double lo, and hope you remember not to coast down a hill up to 25mph with the clutch in causing your clutch to turn into a frag grenade...

What school you in? I just finished WLC @ Lind, Feb 5 and depart for CRC the 28 Feb in Ft benning, 10 days later supose to be OIF but who knows maybe OEF we'll see.

i've got a really good good mechanic/fabricator/4wd builder going to do my SAS while I'm gone. Ran uot of time and want it wheelin ready when I get back.

The gear guy ZUK is worth every penny of his work and the shipping to him, he's done three 3rd for me. And did a photo juornal on each.

ok so i just talked to my local 4x4 shop Leonard's off road ( great guy does awesome work) its going to be about 1300 for gears installed and then if i want lockers he wont add any more labor to the bill just the cost of lockers, and it'll be about 2 weeks before i can even get my truck in there. my question is trail gear has complete 3rd members for like 6 or 7 hundred with gears and you can get lockers too. would it be better to just get new thirds and install those on my own? (sorry i keep writing so much on my own thread, i am just trying to keep you guys updated)

I've had one other guy install gears for me, something wasn't right so I stamped and sent it to ZUK. I would have had problems with the first setup. Because ZUK photo'd everything I got my money back for the original install.
