I have swapped vvt to non-vvt diffs (the other way to you) and had to grind at the front axle casing a wee bit, thus I would assume that going the way you are shouldn't need any extra clearance?

Yes, if u need to grind at the front axle casing a wee bit (the other way, from VVT to Non VVT), I dont undestand that i need to a extra clearance hahaha.

At final, when I dismount front diff I will see.

I've actually done the opposite with the Gold Daily Driver Riccy... it's a VVT model and as I'm running 235/75/15s on it (with a 2" + 2" lift on it) I've swapped the VVT diffs AND transfer box for earlier ones to correct the gearing for the tyres. No grinding was needed for the fitment.

The one in the garage is going the other way, that's an old Jimny having VVT diffs (keeping the original transfer box) to alter the gearing for 30" tyres. Unfortunately I've only done the rear diff so far so can't comment on how the front one will fit...

BUT...

When I fitted the Vitara LSD in the front diff of theS200KYS Jimny (machined to suit by Rockwatt) I then had to take the angle grinder to the front axle casing as described above...

Having a search back through the Bits4Vits archive... here's a photo showing how much had to be removed -



Note there is a similar notch in the bottom of the axle casing but it's slightly obscured by the "B" in the photo's watermark.

Hope that helps Lark?

Yes! Perfect! Thanks for the help!

A man who has made the swap (non vvt to vvt) has sent me the next photos, similar that ur photos S200KYS.

When I put the both diffs, I will do a DIY.

Hey guys sorry to jump in but im a little lost... i have a VVT and am going to be running 31's so am i right that NON VVT diffs will bring my gearing back towards normal? i know that it wont be the same as before but every little helps lol

I can get ahold of NON VVT axles for cheap if thats easier? looking at getting a set of axles to weld up and add gussets to anyway so which would be the best option??

Yes, the gearing will be close I have 235/75/15s on mine (29") and the gearing is great, a little bit low if anything, as it accelerates like a little hot hatch...

Here's the diff and trabsfer box information in the BigJimny WiKi - www.bigjimny.com/mediawiki/index.php?tit...erential_information

So you can see your current diffs will be 4.3:1 and the transfer box is 1:1 and the older diffs are 3.909:1 and the transfer box is 1.32:1

So I swapped the transfer box and diffs from an older Jimny into my VVT Jimny...

Next question I never even thought about I just took it that it was a VVTI is this engine a VVTI???

Thanks for the info last Jimny I had was a 8v
