Question SOA Steering Question

Okay this may be a stupid question but anyway,The crossover steering set-up that BJ's sells,http://www.bjsoffroad.com/CartGenie/prod-883.htm is that what is needed to do a spring over conversion? I have read about high steer setups, but not really sure what that means, any help would be greatly appreciated

Cross-over steering is when the draglink from the pitman arm to the passenger side knuckle goes above the leaf spring (mounting to a steering arm that is mounted on the top of the knuckle - the knuckle needs to be a "flat top knuckle") and the second drag link goes from the passenger side knuckle to the driver's side knuckle below the leaf spring mounting to the kncukle in the stock location.

High steer means that all of the steering linkage (drag link) is above the leaf springs and mounts to a steering arm that is mounted on the top of each knuckle. Each knuckle needs to be a flat top knuckle and they need to be machined, drilled and tapped for the steering arms. The passenger side steering arm will have two holes in it for the steering drag link and the driver's side steering arm will only have one. Take a look in the off-road section as there are some decent thread about highsteer systems.

This s a pretty good article about flat top knuckles and high steer - http://77cj.littlekeylime.com/flatop_knucles.html

This is what a cross-over steering system looks like (it's on a D60 front axle but the same rules apply):


This is what a high steer system looks like:


This here is what a flat top knuckle looks like (passenger side and drivers side w/steering arms):



This is what a flat top knuckle (left) and a non-flat top knuckle (right)look like side by side:

Hey thanks for the info , but one more question, how well does the cross over system work on the SOA setup?

Pretty well actually. The only difference between the two systems really is with a high steer since both drag links are above the leaf springs, they are less likely to get hit on a rock or stump where as with the crossover steering, you have a better chance of hitting the lower one.

If this is a DD/weekend wheeler (i.e. - class VI roads), then the crossover steering is fine. If you are planning on taking on some more challenging terrain, spend the money on a high steer setup and be done with it.
