I believe the Polaris Predator uses this same setup. It would be a good experiment for an LT.

I never knew polaris had that set up! I wonder if the "pro steering" could be retro-fitted to the lt. It looks well built.

Is that a different arm off the spindle? I have a 87 lt500r and mine is offset or has a bend in it, yours looks straight.
Im building mine now, just got it all back from powdercoat. Looking for camber shims now. LOL

Still debating on making more, seems all that purchased them like them, its that I have to run 50 sets to keep pricing down,  and the bolts are not cheap either

Old thread but have been researching trying to find the best bump steer fix for my 87 LT250R with +2  A arms.....Messed around and flipping the spindle arms maxes out my tie rod ends at full travel,likely the added control arm length...I noticed buckeyes helm joint setup on his 500 has his tie rod sleeves pretty much parallel with his control arms...Just curious if this is due to his helm joint tie rod setup??? Could this possibly be beneficial on the 250's?

I think the idea is for the tie rods to not be parallel.

Looking at the modern bikes, the tie rods are flatter.  I think if you make the mount to the spindle taller, you will benefit.

Recently there was an episode of Hot Rod Garage where Tony Angelo went in depth of how to fix bump steer on his fishtail Cuda.  I need to watch it again.

I was under the impression you want the tie rods parallel with the controls arms or as close as possible.Buckeyes LT500 in this thread looks that way and he says he has limited bump steer...My 250 with the +2 A arms has ALOT of toe in/out throughout the suspension travel.Trying to reduce it as much as possible.The +2 arms seem to make the problem even worse.:(

check this link out.  Tells you exactly how to measure bump steer and how to fix by raising or lowering your tie rod ends.

It would be really easy to have that piece that mounts your tie rod end to your spindle modified to raise the tie rod.

My problem is I need to get the tie rod lower at the spindle.Even if I lower the arms/steering levers I can because the tie rods are "maxed out" as far as the angle they go without binding.That's why I was wondering about buckeyes 500 setup as his tie rod sleeves seem parallel with his a arms.With the quad on the ground is fine but with front wheels off the ground and suspension as full travel as when I jump the quad on the track the tie rods will have serious stress on them as they don't swivel far enough :(
