spindle-axle relation

On most straight axle setups, the spindle is more or less centered on the axle. I want to use a set of spindles that will place the spindle center slightly above the top of the axle. What effect is this going to have on the caster and steering stability?

Why don't you just get a dropped axle?

I really don't think it would change anything about the geometry or stability, as long as you aren't changing any caster or king pin inclination angles in relation to the spindle centerline or contact patch of the tire.

Now if you change to a spindle that will move the tire contact patch in or out, you will change your scrub radius. That can affect steering effort and feedback from braking.

Do a google search for "scrub radius" and you'll see why the changes could vary, depending on what gets changed.

BE different....ACT normal.

No one is completely useless..They can always be used as a bad example

What I am doing will improve the scrub radius from 2 5/16 to 15/16. The torsion front suspension is designed to run behind the tube axle on the same plane. The axle itself is split and joined with swivel (for lack of a better term) that will allow the hairpins to work with no bind or axle tube twist.. Also makes caster independently adjustable while still working as a straight axle. Doing it my way so I can run the brakes and wheels I want.
