Rocklobster transfer cases for Gen3 Jimny.

Does anyone know of anyone reputable making rocklobster transfer cases?

Any idea on what the upper end road speed/rev relationship over standard config'?

Thanks

There are some companies who might be considered competent but personally I would prefer to build up a second box myself with commercial gear sets like sumo. But that's because I have both trust issues and a fairly useful skill base.

It all comes down to what car you got and what tyres you want, and how wildly you want to use the car offroad.

I have the later gen3 and have been pleased with a trailgear gear set and reinforced steel mounts for the transfer.
The later gen3 have lower diff gears so not so prone to breaking the transfer case.

If you have the earlier gen3 with large wheels and/or more HP and do hard offroading, a full cradle SJ-type transfer case would be smart.
I had an SJ with 31" tyres 4.16 :1 transfer gears and just the reinforced mounts. Did pretty hard offroading without going too wild, but with the 62hp engine I did not break stuff.
The SJ had more or less the same gearing as the early gen3 so it is almost comparable.

Have an older Gen3 (2004).
Tyres are aftermarket muddies but pretty much same diameter as originals.

Has 1800cc VVT liana engine in it with HD clutch.
I drive in and out of a farm everyday on logging trails but don't any serious offroading where I'm giving it death - its my daily driver so not going "balls to the wall".

Was mainly interested in the upper end road speed (w/rocklobster) as a daily driver, would be nice to sit on 100kmh at roughly 500+ less rpm.
(The Jimny is currently bulletproof on the logging trails in low 4WD even in middle of winter).

Not sure what you mean by rocklobster here.
I thought that was the brand for a guy earlier that made transfer case cradles (large reinforced cages) so SJ transfer could fit in a 99 to 04 Jimny, and put low gears inside them.

Given your setup I would only change the mounts to steel. The reinforced type, several shops got them.
You would not need the full cradle.

But if you are not so interested in gearing the case down in low for large wheels, but up in high you should not be looking into the SJ type case low gear options as none of them will give lower highway rpm.

I believe there are some kits that changes the low gear only in your excisting transfer case. Highway rpm will be the same.

I cannot see any easy option to get lower highway rpm other than larger wheels and swapping to one of the low gear only kits.

I've seen quite a few requests like this over the years and the aim is usually to reduce the fuel burn, the point you're missing is that Suzuki's engineers designed the engines to rev, to produce the power they needed, and geared the vehicles to suit, the only time you need to regear is when you change the wheel/tyre size and for most folks that's a larger tyre, and that's the scenario a rocklobster is designed to be used in.
