Rock Lobster or other reduced ratio boxes

Right, a Mate has just stuck a set of 31x10.5x15's on his sports track and it looks HUGE !!!

So much so .. I want a set... but given the 215rx15's are pushing teh standard gearing to the limit, and I really donot have the time to source and build a TX box, what is the easiest option .... Im happy to part with money if it gets me to my goal

Can they be bought ? how easy is it to sourse the bits and getone built / build it yoruself ?

Ive seem Martin's How to guide and I dont have the time or space to attempt anything like that.

A Bolt on ... away you go solution is I guess what im looking for ..

Anyone ?

Rs manafacturing does a full bolt on sj kit or you can get some trial jimny gears put into your t box. Thus keeping orginal speedo drive and props etc. And not fitting an old sj box.

Let me know how you get on cos I am looking todo the same very soon.

I was not personally happy with the special Low Ratio Jimny gearset fitted to my Jimny

I believe mine had had a chain replaced (by changing the transfer box) before I got it and I had to do the same shortly after I got it. The chain slipped badly. The Special Low Ratio Jimny gearset people suggest you should fit a new chain at the time of putting the new gears in but at over £300 this makes it a very expensive option.

A Rocklobster is quite cheap and easy to make, you need to get hold of two transfer boxes, one from a 413 and one from a 410. The 410 ones are getting rarer and more expensive. Then for about £100 you can get the gears cut and swapped.

Rebuilding the transfer box is quite easy despite the apparent long list of steps in my guide.

If you then fit a commercial adaptor kit (Off-Road Armory or -Rob Storr) it becomes a pretty much bolt on solution.

i went down the rob storr route and cant fault it. refurbed box with machined gears, not cut / shut. new bearings too
i paid extra to get the full bucket style fitting kit, totally solid bit of kit, could probs jack the car up off the tbox now. i also bought some poly bushes as the standard ones are a nightmare to work with. seriously the best money i've spent on the car.

that looks like a serious piece of kit the plate it is mounted on... think you could easy jack the car on it. bet you cant wait to get out there and try it.

Wow .... Gimmi gimmi gimmi ......

Can I ask how much ?

I tried to email Rob but the mail bounced.
Im out of teh country at present, but will certainly try and chase him up when I return
