Thread: rover diff's ARE cheese!

What ratio's are available with the toyota and nissan gear?
I run 32" tyres on the road so don't want to change to 4.11's from 3.54's,I think I've read somewhere that toyota do a 3.8:1 which could work.
I was considering the dana 44 due to its wide selection of ratio's and aftermarket goodies available in the US.Even if they were grafted onto rover housings like the salisbury.I just don't see the need to go that big(salisbury/dana 60,ford 9") with 35"tyres.If I could get toyota centres with 3.54:1 ratios I would probably use them with 30 spline axles all round.What do you use for drive flanges then,Rover tracks or Jac Macs?
Diff clearance is pretty important as well as overall weight so want to keep it as light as possible.

Rangieman was talking about a vehicle prepared for the Outback Challenge and planning to compete with rover diffs that have been pegged as a strength measure.

Yes you can drive to finish and not compete in the harder stages, or finish outside the time limits.

The days when rangies used to do well in this event are long gone.

It costs a lot of money, time, and effort to prepare and compete in this event. Why anyone would want to go in with a handicap like rover diffs for all of the wasted cost and effort for the misery is beyond me.

Nissan H233B diffs are strong enough in a rover - anything smaller would be risky with 37's. They loose 15mm ground clearance underneath the pumpkin compared to a flat bottom rover pumpkin. The centred rear diff is ok for vibration if set up properly and a driveshaft with decent uni-joints (i.e. not rover drive shaft) is used.

They do make a toyota 3.54 set of gears, and jacmac had a heap of 3.54 high pinion gear sets made for the front just for this conversion. Rear set is around $400, front from jacmac was around $750 from memory. Iwas going to go this route when i had my toy diffs, but it was going to cost me another nearly $4k by the time i did a ratio change then lockers aswell, so parted them out and now doing a detroit sals and maxi front(until it breaks)

I meant to add he is also running Ashcroft 4.11 ratio,s But then there are still the odd critics on here that think anything to do with rover drive line is crap , At least he is giving it ago even with rover diffs ,
Thats more than alot of others on here have done

By the way i have blown many a banjo type rover diff ,well never the crown wheel & pinion only ever the x shaft

Thank god for the sals grader

Keep in mind the Toyota diff when used in the front is notoriously weak in Reverse. Many Toyota's have broken the front diff while snatching in reverse.

Personally I would get a Nissian or Toyota if you want to go away from Rover Diff's.
