31 to 33inch tires. do i have to regear my mk

[Mintoy]

hi guys. was reading the threads of body lifts and i'm thinking of adding 2 inches to accomodate 33 inch tires. my mk has a sd33t and has a stock 4.37 diff ratio. can my engine/clutch/transmission take the increase strain of the new tires? do i have to regear?

if yopu have the turbo model, you will have enough power to drive them without dramas, but, to retain factory gearing, you could install a set of 4.6 ring and pinions, so it will feel exactly the same as it did on 31" rubber,

you dont "HAVE" to change gearing, but it could be an option, if you feel you lost heaps of power, but i say i wouldnt worry bout it

I was running 35's with that gearing without an issue....the only reason I was going to change to 4.6's was to regain a bit more crawling ability but nothing else....

SD33T and 35's = easy....

do it now.....

to regain factoey gearing as per 31 tyre you would have to go 4.8's on an MK SD33T which has factory 4.3's

4.3's + 31 = factory gearing
33 + 4.6's = factory gearing
35 + 4.8's = factory gearing

I know someone who has a set of 4.8's for sale at the moment in Melbourne for an MK/MQ...

indeed, but he has 4.3's which were standard with his 31" rubber,

he said he got "33"" rubber now, se he would need 4.6 to retain factroy gearing................................

thanks guys for the info. i will scout around for 2nd hand/ surplus 4.6 diff. too bad i can't avail of parts from your parts cuz i'm on the opposite side of the world.

don't go the expense of diffs for the moment.....

Just run the 35's with your 4.3's....

Plenty of people here have......

It would be no different than having 4.6's and running 38 Swamper which many people on here either have or do....

cheers

Just think, alot of people with GQ's run around with 3.9's or 4.1's

they pay huge money for 4.3's or 4.6s, were lucky!

hi james,

here in the philipines. 35's are hard to come by. 33's are gainig popularity but thier still kinda expensive. so, i'll go for the 33's first. thanks for the help

mind you there are a few extra ponies under the tin lid and an extra cog in the box

the 35's & 4.3 ratio will work, look to update ya diff further down the track.

38s on the 4 speed with 4.6s suz mega ass....
wasnt until the 5 speed did i get better gearing, prob was i max out at 130.......
at 2500 revs

[tuff dog]

G'day mate it makes it hard when everyone has a driffrent answer. I had 4.1's in my ute running 31's. I just changed to 4.6 running 35's and now the old girl reves a little harder so if you put 33's on 4.3. You would shit it in.

[Screwy]

4.3s on 33's are ok

4.3s on 35s is mega stretching it....

MY GQ lost 50km per tank out of its around town range when i went form 31's to 33's and is slower too...... its only got 4.1s i think...

screwy

[MQ080]

4.3's on 33's will be fine. Anything larger, think again.
