OT- FJ55 \"Iron Pig\" Questions

OT- FJ55 "Iron Pig" Questions

A buddy of mine recently bought a 76 FJ55 with a straight six and a 4 speed tranny, thats about all we know about it. We are wondering about where to go from here? He read about spring over possibilities, anyone know anything about this? I am sure it is very similiar to a jeep SOA, but wondering if new drivelines are needed and how steering can be set up? Also does any one know what axles are under this thing and how strong they are? Compare to something? Up to what size tires can they handle? What about popular engine swaps? Just about any input anyone has would help.

Thanks very much

try th land-cruiser section here, or on pirate4x4.com

very worthy vehicles, with a HUGE following.

the SOA will be very similar to a Jeep, but the details would be covered by a Toyota board better im sure!

Re: OT- FJ55 \"Iron Pig\" Questions

The FJ-55's are pretty sweet, ugly to many but treasured by a few. From 76 and up they have disc front brakes, that 2F 6 cylinder will run forever. Popular swaps are the SBC 350 pretty much like what the jeeps run. The driveshafts are long so angles won't be a problem. More info can be found on the pirate board or here is another.


Have fun with that.

I could be wrong but I thought 55's had a very very short front driveshaft. The axles are pretty stout, same stuff as FJ-40's. The rears have huge shafts but neck down to a D44 sized shaft at the splines. The weak spot will be the front birfields. They have a small pinion shaft that has been know to break. Not much aftermarket stuff, unlike the mini trucks. And parts are expensive.
FJ-55's are cool, but they dont call them Iron pigs for nothing, they are extremely heavy.

Never did much with mine, very mild wheeling to get to fishing spots with my grandpa (r.i.p.) up in Bishop years ago. Never had any trouble with the front axles, just be real careful to disengage the parking brake when your in low range, easy to snap the mounting. I rebuilt the engine after 130k, put another 60k on it before I rolled it. Iron Pig is right, but it was great for hauling people & gear. Oh the memories... Met my wife in that thing...
