Does anyone have a quick fire way to work out weather I have a rocklobster box in my SJ or not? Like if I turn the prop the output shafts fhould turn X times? I don't have a working speedo before anyone suggests it should do X speed at X rpm
It seems to drive fine around the section in High, and low feels much lower than it normally would but I've never owned an SJ before, and this is on 31" tyres which I thought should be almost unusable in high.
Edit..after deciding to have a further read of material I found, the rocklobster box is 4.16 in low, so I assume if I were to turn gearbox output it should turn around 4 times for every 1 turn of the driveshafts correct? And I would hazard a guess that a standard transfer is more like a 2:1 ratio in low?

Yes output should turn once for every 4 turns of input in low for 4.16 gears. Standard SJ413 ratio is 2.268:1 in low and 410 is 2.511:1.

Also the 410 farmworker utes were 3:1 in low. Like mentioned give it a spin and then give google a whirl. Lowrangeoffroad has some good info

Re: SJ Transfer ratios
Well just got round to checking this while its up on stands again.. around 4 1/4 turns to one! Score. So its either got crawler gears or more likely given how long since it was last used, as rocklobster box, hopefully well made. Adds to the mystery of where it came from since this makes it even more likely that it was once someones prized club or even trials truck
