Coil Sprung Special Question

[I Leak Oil]

The biggest hurdle you have to jump in looking at putting coiler axles in a leafer is the steering. No two pieces of matter can occupy the same space at the same time.....If it weren't for that I think the conversion would be very popular. But it's not, and for good reason.

Oh....I thought the question was about putting disco axles on a designa chassis.....if they are going on a leaf chassis its a bit trickier...lots of stuff to cut off the axle tubes that will be in the way of the new leaf spring perches. However, one trick you can do to ease the steering is to replace the passenger side knuckle with a right hand drive unit...then you can put a connecting link up front instead of behind the axle which I think it is on disco axles.

I do have a RHD Series or do you mean a RHD donor axle. I was contemplating keeping it a leaf spring unit with parabolics, but I would like the performance of disc brakes and if I could find a RRC or Disco for not much more than a front disc brake conversion well, it just made sense to start on some homework.

Would the series ring and pinion fit in the RRC or Disco axle housing so I could keep the original gearing?

I meant using the knuckle from a rhd disco/rangie axle as that allows you to move the drag link to the front...which I think solves the interference problem with the leaves....but I might be incorrect.

You can put the series diffs in the older 10 spline range rover axles and maybe the earlier disco axles...but the discos went to a 24 spline axle mid 90's.

I can't understand why Designa does not have a US distributor. There is plenty of interest and I think they would sell a good number. Most US series trucks are either in need of or already have been frame swapped and there are plenty of Disco 1 and RRC axles and suspensions laying around cheap too.

I tried to pull this off with Designa chassis, as well as our hosts blessing as they were both sending me inquiries. It all comes down to having to buy 10 chassis at a time to make it worth doing and there just is not enough interest when it comes down to actually spending the money, and that was just for the frame. When the actual cost of conversion is considered most people tend to stick with leaf springs. Even if they are doing their own work.

That said, I'm still working on it.

Thank you for all the info. I think I will just keep my axles and eventually do a front disc brake conversion.

on the Saab site my friends and I have put together we organized a group buy for 12 custom built limited slip differentials that cost around $1000 each and we managed to pull it off. There was a recent group buy on the moto forum I frequent for $1000 gas tanks...so it is doable. Get numbers for prices and post the idea to several forums and see what you can generate. Then set up some sort of account with secure payment etc...or maybe work it through a vendor like RN so they are a trusted broker....and if the group buy falls through then money will come back. Then go from there.
