410 transfer box

The 410 is a direct ish swap. You will need different propshafts as the bolt holes are different and one of the shafts is too long. Have a quick search and all the specific requirements are on here.

Welcome to the forum.

You'll need a Rocklobster. Only get it from Richard Redacted (Rockwatt) and discuss all new gears or polished gears to keep the noise down.

Or change the gears in your Jimny transfere if your Jimny is 2005 or later.

Where do you get the ready made gearsets for the SJ transfer box? Who makes them and who melds the gear to the shaft?

The only ones I'm aware of are Trailgear gearsets and they are for the standard Jimny transfer box.

There's 2 reasons to go Rocklobster over Trailgear gearsets. The first is the SJ box that the Rocklobster is made from is all gears and no chain, which stretches with the increased torque on occasions. The second is the rubber mounts of the Jimny box will tear out and you need Heavy Duty arms from the transfer box.

You could use through bolts to mount the Jimny box to the chassis but you still have the chain issue and you'll get vibrations through the car the same as comes with a Rocklobster mounted with the through bolts.

The through bolts also transmit transmission noise as the bolt goes through a hole on the chassis outrigger and a hole in the transfer box cradle or mount. If you can stop that bolt touching the sides of the hole you're a better man than me!

So whilst a benefit of the Trailgear gearsets is that they are quieter, the Rocklobster can be quiet if no old gears are meshed with new ones (all new gears used) or old gears are pished to suit, which Richard Redacted does at a slight extra cost.

Mine is an old one with old gears on new from before Richard had the tools to do all of this and is a little noisy.
