Where can I buy one of these Rocklobster transfer boxes? Roughly how do you install one?

I'm intending to do my homework and do this right. I'm going for a minimal yet high quality build with an on/off road balance but leaning a bit more towards off road.

Thinking of just going with a 4 inch suspension lift, 31 inch mud tyres, a snorkel and a gear reduction of some kind.

Seems to be difficult to find all the info. There seem to be no youtube tutorials on this stuff.

Unless it's evolutionary based on overcoming difficulties with an existing modification on increasingly technical terrain, there's as much need for a Jimny to have a 4 inch lift as there is for a bull in a milking parlour. Oh it's going to look impressive for sure but when someone drives past it on a set of modest tyres with a minimal lift because they have good skills and happened to have spent their money on locking axle diffs instead, then looking cool becomes a moot point.

I know that makes me sound like a fun sponge but a very lightly adapted Jimny is essentially unstoppable in the right hands. Think of a Jimny as the off road equivalent of a sleeper, looks like a ratty 318i goes like an M5 on nitrous.

You need SJ 413 transfer box
6.5.1 gear set jimnybits
wide angle HD props jimnybits
A purpose built cradle to make SJ transfer fit into the jimny
£1,500 should cover the cost, if you can fit the gears and do all other work yourself
Welcome, to the expense of doing it right :)

Hmm.. Would 29 inch tyres and a 2 inch lift make more sense? If yes which Lift kit and mud tyres would you recommend?

Yes that would make a very capable mixed use Jimny. Budget is the most obvious limit. But trailmaster is high quality as is old man emu. Most branded tyres will not disappoint, offerings from bfg and maxxis are popular.

As others have said- fitting a big lift, 31's ect doesn't really get you that much further. The main problem with tall 'cool' looking jimnys is the springs are rock solid and you have the centre of gravity constantly against you, best option is to aim to build something that all works together. biggest tyres possible with the absolute smallest lift possible (i run 245/75/16's - just under a 31) on a 2 inch lift with only a bit of trimming, but to keep it driving nice on the road its not just a kit. I tried a 2 inch procomp lift - was ok, full 4 inch lift kit- like riding on a block of concrete, i now run a pair of standard passenger side (i think - can't exactly remember which side) on the rear, cheap vit mods shock absorbers (had avo's on previously), home made shock brackets at the bottom, made a set of spring mounts to sit on top of the originals out of bits off a scrap axle, 4 inch radius arms all round and plus 2 inch jimny bits springs on the front. Now this sounds like alot of work but it rides brilliantly, handles well - you can let go of the steering wheel at 50 and it won't wander or wobble. Biggest thing though was a 6.5 trail gear gear set, its really really really really (you get the idea :laugh: ) slow in low, this gives you so much control as you can just crawl along picking your line rather than having to go at it gung-ho (as a result i have never broken anything whilst green laning) , admittedly i shouldn't have gone quite so low as it does make it rev alot on road a 5.1 ratio would probably be ideal and if doing it agian i would import some 'sumo' branded gears from japan as these wont chatter as much as the trial gear. Yes it doesn't look that modified and like a cool little monster truck but it performs well on and off road, its only taken 5 or so years of fiddling to get it here, so to reiterate, do it right once and make it reliable. Hope that helps a bit :)
