Yes Dave, axles over here are halfshafts back home!

axles and driveshaft terminology causes so much confusion.

I find when teaching this stuff that it was a lot clearer to use
Halfshafts
Propshafts
Axle housing

and not use driveshaft at all.

The bit that still spins everybody out is commonly defining

The Nissan Patrol front ends that are used to replace the Rover assembly here are a touch wider from the radius rods out and it makes a hell of a difference in steering lock (and obviously stability)

I know that when we went from a GQ to a GU Patrol the tighter steering was very much appreciated, and it was all from a slightly wider track.

It's looking very good.

That is such a good point. Almost everybody who is running over 33" is offsetting rims etc to get clearance which has scrub radius implications etc.

Also, will the full fitment be suitable for Disco2 and P38 axles as well as Rover type axles? The other question is what range of ratios will suit the housing?

ORSUM... Might upgrade to this setup if the price is right! Keen to test out the full kit (front and rear).

I'd just be interested in the wider track and stronger axles.

With the touring crowd who more run 31" to 33" rubber, and still fit Maxi axles etc for reliability, this would be an excellent opertunity to just replace axels, CV's and knuckels and get the extra needed to not scrub and not having to off set rims which puts added load on wheel bearings.

The centre is awsome though Dave, great idea for the slightly more serious 4wd nuts out there :p

Looks to me like there's a new ultimate driveline for rovers!

I'm not sure that its suitable for that type of application??? This will be waaaaaaaay overkill for a Rover diff and a lot more expensive than fitting Maxidrive axles and offset rims.The front is a big operation.

Yep, it'll be aimed at the 35" + tyre crowd, mainly the comp fella's and real hardcore weekend wariors.
The complete kit will be $$$ with all those custom bits. It'll have to be for Ashcrofts to get the development $ back.

This could be achieved relatively easily by using a spacer between the diff housing and swivel housing, axle length to match and drag link and tie rod to suit.

Its surprising that nobody has ever manufactured that setup. I'm sure it will sell.
