Hey everyone, I was just wondering if you can run a high steer without doing a spoa conversion, I have a 2" spring, and 2 " shackles, the reason for this is I can get a new system second hand but brand new for a good price, and my tie rods are shot on mine, and the hi steer setup are all heavy duty. Thanks

I don't believe it's possible. It's something I have looked at a number of times, but there is just not enough room - the knuckle can travel up too far relative to the chassis with SPUA to permit clearance.

Hi Andre, it doesn't have anything to do with the lift, it's all about where the axle ends up when the suspension is fully compressed. Whether you have shackles and lift springs or not, the axle can (should) still be able to reach the bumpstop, which is still in the factory position - so there's just no room - the tie rod will be about 1/2 way up the chassis rail.
I reckon you'd need to space the bumpstops over three inches in order to try and run high steer, which, I think, is too much to have the car work well.
I have looked at running it with cars running 2" of bumpstop spacing and it's not possible.
It is advisable to flatten out your drag link angle though - your car will drive and steer much better if you do. A drop pitman arm is the best way of achieving this in your application.
Steve.

Could you run crossover steering instead? Or still no room?

Do you specifically want high steer, or do you just want heavy duty? Pete from Twins Stick Offroad makes a HD chromoly replacement sierra steering setup. It's a bloody good bit of gear. Look here: viewtopic.php?f=15&t=13126

Those arms still aren't bent pushing 33s with power steer and they also tend to collide with the odd rock as well!

6000series alloy is another good material.
