Manual overdrive / Hi ratio transfer gears

[Jon Tallis]

I've got a KZN185 Manual which does most of its time on tarmac, with some long motorway miles. With all that torque it could easily pull a 6th gear. Does anyone know a way of giving it some longer legs on the motorway? Is there an overdrive available for the manual box? What about a higher ratio transfer box off another model, higher ratio transfer box gears or higher ratio diffs? Already got the biggest boots that'll fit in the arches without fouling (275/85's). It doesn't do any serious off-roading (just dragging the odd trailer across fields) so I'm not too worried about losing the bottom end of 'low box'.

Any ideas?

Changing diff gears are only real option.

the data plate will tell you what you have already.

Where's the data plate - is it on the diff casing? What am I looking for?

The data plate is the same plate as the VIN plate. You can find it just below the windscreen right in the centre of the bulkhead. Open the bonnet and look back at the other end of the engine bay and it's there, smack in the middle. On it you can find all the info needed about your diffs. There are two words in black ink: "Colour - Trim" under which the codes are punched and underneath those two little codes you will find the axle code: TRANS/AXLE. From that code you can tell what ratios you have.

PS: I found this pic somewhere on this same site, so yeah, it's kinda hijacked, but for a good cause!
