Topic: 2002 3.4, 5 Speed - Can I Regear Just my stock T-Case?

[ShapeShifter]

New to Toyotas here.  I'm looking for slower low range but don't really need a Taco Box (however a box of tacos sounds delicious).  Is it possible to regear my low range in the transfer case?

No. You have a chain driven tcase. The gear driven rf1a is the case you can get 4.7 reduction gears for.

Thanks for that input.  Its not what I was hoping to hear, but thanks.

If I were to find and install an RF1A top shift using the appropriate MC adapter plate, will I need to change driveshafts?

It's not just a simple swap, the RF1A transfer cases are passenger-side drop, the chain drive transfer cases are driver-side drop.
There was a company called Inchworm that made driver-side drop gear-driven transfer cases where you run 4.7:1 gears, unfortunately they are no longer around. But if you keep your eyes open they pop up for sale every once in a while.

Yes would have to lengthen the front and shorten the rear drive shafts. Also have to get a "lefty" case.

I suggest you look at Low Range Off-Road. Inch Worm stuff is available there.

Good luck.

Thanks.  I already looked at low range.  All they seem to have is their Trail Creeper box which is a hundred bucks more than a Tacobox.

Ill have to keep looking for used.  All I want is 4:1 - is that too much to ask.....?

You need/want a crawl box. Quit lying to yourself

But that would mean loosing one cup holder.  I need both - one for the gin and one for the tonic.

Triple stick...problem solved!

That reminds me of a buddy that had an Atlas transfer case in his Jeep.  He had to stop and retrain himself how to use all the different sticks everytime the trail changed.  He had like 5 different sticks.

We used to say "too many sticks, not enough marbles". LOL

I heard that after Trail Gear bought Low Range, they did not retain the partnership with inchworm. It doesn't look like inchworm is in business right now.

Good to know... too bad for Inch Worm.

Inchworm made some good stuff. I had a blinged out 2wd a340 with their adapter to a 4.7 case in one of my previous rigs.

Same here... my A340 has a shift kit which helps.  The 4.7's rock.
This pic was when I was still IFS.  That is no longer the case.

I just had to do a driveline modification and it was surprisingly painless. I replaced the a340f with an r150f in my tundra and since everything came out about 2” shorter I had lengthen my driveline. It cost $350 to retube it, replace the carrier bearing, and replace the old ujoint.

I still have a chain driven t case so I’m stuck with the same gearing as you but I like having a manual transmission.
