Thread: Best ratio for 35s

Depends on what you're after and your driving style

4.11's will get you back to close and 4.7's will get you a tad under.

the td5 will motor along on the 4.11's quite nicely but will be a tad under on acceleration, which if you dont tow heavy or drive like a ricer will be almost unoticable.

the 4.7's will cut your top speed a bit but will give you a bit more pull. It will also drop your crawl speed a touch which also gives you a bit more reaction time when reversing or low ranging.

good to know cheers now best of both worlds 4.7s with disco high range with defender low range ?

low range remains the same across both.

ITs been a while Id have to sit down and nut out the differences between the 1.2+1.4 with the two different diff ratios.

But 4.7:1 gears have smaller and weaker mesh area due to the pinion size and is not up to use with 35s.

Is there after market gear set strong enough to take on 35s (and the odd dose of red mist) thanks for the input

just peg them and they do fine.

Not likely. The rover pinion is just too small.

Ashcroft heavy duty ring and pinion with reverse cut are the strongest that suit your rover front diff, but you would need to research to find what of those ratios, can be matched with available ratios for your rear Salisbury diff.

You may need to look in the USA for suitable ratio Dana 60 ring and pinions (the Salisbury is based upon the Dana 60. There are some things to watch so come and check back here if you decide to go that way. For example thickness of ring gears (both Salisbury and D60) change at some ratio point, which I can't recall of the top of my head.
