Thread: MII ride height and spring rates????

Tweet

That is DEFINITELY NOT a Heidt's spring hat. That's either Fat Man or one of the other bottom pricers. Can't tell on the control arm.

Here's some pics that might help you figure out what you've got going on. This setup has a sway bar. It attaches to brackets on the lower control arms which, as you can see, are tubular also. This bar is from Chassis engineering. These control arms are also the "narrowed" versions, 5/8" shorter than the stock MII dimension. This is also the dropped spindle, in the one pic you can see the shape of the spindle shaft butt end and the distance from the top ball joint.

I can't tell you the length of the springs as I never bothered to measure them, it's sort of pointless anyway. The critical factor is getting the lower control arm to set parallel to the ground at full load ride height to get the geometry right. This picture was taken before I shortened these coils one turn. In my case removing that coil set it just right. The third picture shows how our steering shaft was routed, though you'll be dealing with different dimensions so this is only reference/inspiration.

One other possibility in your case may be that the crossmember was set into the frame rails deeper to get the nose down more, worth looking at.

One more thing, the back end on yours needs to come down at least two inches to cover the top of the tire visually so it won't look so dumped off once that's done.
