Yup, they bolt-on where the spindle normally bolts on both front and rear. Rover axles are full-floaters, so this isn't very hard to do. However, the biggest question is the strength of the unit and the axle housing where it mounts on. I can see gussetting the rear, but I'm not sure what to do with the front. They're saying just use the stock front swivel ball. I've never heard of anyone breaking one, but I'm sure it can be done and this thing will probably do it. Also, the 24 spline axles are a weak point. I think the idea is that the reduction being after the axle will help to offset some of that weakness.
I'm only planning on running 37" tires with this set-up. My truck almost clears them now and I would be able to drop down to shorter springs and bumpstops to clear the tires. Actually, I'd get long, lighter springs that would allow good extension and compression.
I don't think axle-hop will be a problem as I have coils on all 4 corners and the links are quite stout. I think this is going to be a good test for all of it.
I see two possibilities here:
Either my set-up is strong enough and it works well, or I'll have a catastrophic failure of the axle housing at the spindle mount, a link connection, or both.
I'm hoping they'll work with me on any repair/redesign necessary.
