Diff Ratios

[Tomo_89]

Im currently running 35's on my gu ute with standard ratios and it seems to push them ok but i was just wondering what sort of a difference changing the ratios would make? is it worth it? What ratio?
Any info would be greatly appreciated.

cheers

if you fit 4.6 ratio it will be like driving on 31" tyres, coil cab normally have 4.11, leaf normally 4.3

[Tomo_89]

so would you recomend it? i've always had 35s so im not sure of the difference in power?

I like the 4.11 with the 35's, but I have turbo intercooled TD42 so no shortage of torque. My ute is back to 4.11 after finding cracked crown wheel on the 4.88 gears, I do have 4.6 for it though.

For an everyday driver I would leave it at 4.11, if you have to go down to smaller tyres it will be ok, with the 4.88 we went back to standard tyres and where doin around 80km at 3800rpm.

If your goin bigger tyres for play, fit tranfer gears, 43%.

Diff ratio's are a hard 1 to give advise on, it depends on what you want the truck to do.

Being engineered to run on 35's myself, they will be my daily driving tyre, should i swap out the 4.11L1 ratios for some 4.625's or would a 4.3 be a good compromise

is it a Auto or Manual thats the biggest desider.

if its a auto I'd go the 4.6,be much better at cruiseing speed

Got 4.6's turning my 35" Mudders. Brings speedo and revs back almost to normal and I'm not trying to push pistons through the sump revving the guts out of it just to maintain a decent cruize speed.
But as 'nastytroll' says, you need to change your transfer gears for any decent crawling. Standard gears are just too fast.
Depends on what you want to do really.
