Doing your homework on a rack and pinion installation is mandatory!!!!

Powerrodsmike illustration from Longacre is right on the money. The inner pivot must intersect with the pivot points of the control arms. Rack travel is important in relationship to the steering arm length, or you will wind up with something that might turn like the Titanic, and just might remove a few fingers when you hit a small crack in the road.

I've been a rod tech at Speedway for a couple of years now, and some of the calls I receive are almost comical.

One of them being this:

" I mounted my Mustang rack on my straight axle, but the car steers backwards, what's going on." -------- classic!

Using a front steer rack on the back of the axle is what happened.

Last week I had a customer that tried to connect to spindles together with a solid tie rod arm on an old Chrysler independent front suspension.

Didn't work too well.

When you are playing with suspensions, it just doesn't pay to "make it fit".

You've got to spend alot of time studying suspension theory and you have to follow the rules or you will be unhappy!!!!
