3.909 in IFS Fourtrak

Post by X90 »

Hi! Is it possible to fit 3.909 gears from 2.0 Petrol Fourtrak on solid axles to the IFS Fourtrak? This should compensate the overall ratio diffrence after putting in 33" :cool:

Another question: Solid axle Fourtrak is badly known for it's week CV's. Do an IFS version have the same problem?

I wouldnt suggest leaf sprung Rockys have weak CV's. I have a detriot locker in the front, have had for about 6 years or so, and only done 1 CV. And, no, my Rocky doesnt get treated like a pussy cat.

Thanks for reply! I heard a lot of people complaining about Rocky's CV's, but I'm glad to hear that's a myth :finger:

Greatings!

Greatings!
there is a lot of difference in strength and durability between the solid axle Rocky's and the IFS (F300) 1600cc petrol Rocky/Feroza's .. these are not as strong as the solid axle f70 diesel leaf sprung front Rocky's.
The IFS Roc/Fez will take a fair amount of punishment but they dont take kindly to going airbrone in the nose at full noise and coming down on hard surfaces with the wheels spinning, i know of a few members in our club that have broken CV's that way (one in a 94 Rocky and the other in a 91 Fez (both IFS 1600 petrol both on the same hill too ... to compensate for that I tend to back off at the apex of a hill ...so far so good :lol:

I don't reckon there's many CV's out there, if any, that like coming back to earth, full noise onto a hard surface ;)

But if ones going to be stronger than the other it will be solid 110%. According to some onlookers, I've given mine a fair caning over the years, haven't busted a CV yet.

Once again: I'm asking about IFS Fourtrak, not Feroza/Sportrak.

Ok, with regards diff ratios. my understanding is that diesel ratios are 3.3636, where as the petrol (2 litre 3Y 4 cyl) is 5.?????
I could be wrong.
