Anyone running a bronco?

Why you say this? I've never had any problem with using it (when correctly used/modified itself)... Take a look at this, it's a really good TTB steering article...

The problem with the Super Runner steering is that its an expensive, band aid to the issues in the stock steering. Honestly, a $400 kit designed to fit lifts from 3"-6" is not going to fix the toe problems. There are too many variables in the idea, too many links at different ride heights to try and keep in the "ideal plane." You won't be able to truly fix this problem unless you have a go-fast shop custom build you true cross over/swing arm linkage; which starts at around $2k.

The truth is, Ford has a half way decent steering set up from the factory. The passenger side link is the ideal length and pretty close to the ideal angle; the driver side on the other hand is all out of wack. But by using the Super Runner kit, you remove the one good factory link and install a complete out of good spec'd geometry kit. The idler arm is weak, expensive, and non-serviceable. It has to hang down low to create the flatter angles to reduce bump steer. But by doing this, Superlift has created equal length arms, which are far too short to use in the suspension travel. I guess if the truck never leaves the road and cycles more than the typical 3", it wold be better suited, but when you're using 8-12" of travel the links are far too short. The shorter links actually increase the variability of the toe over the course of the ttb travel arc.

Comparing the stock linkage and the Super Runner linkage above, you can first see that the in the picture of the stock linkage, the wheels are turned drivers a good amount. This is deceiving to the eye, so I'm pointing it out.

The stock driver link and both Super Runner links are about the same length, the SR links are about 2" longer and about 5" shorter than the stock passenger link.

If you understand what I've just said, then you'll realize that the Super Runner kit is not ideal and is an expensive alternative.

The most money efficient thing to do would to keep the stock setup, but modify it using stock parts. Thats the great thing about Full Size Fords, parts are interchangeable with just about anything Ford made in the 80's and 90's (with the exception of 1987, when Ford tried Flat Top hubs--- AVOID 1987 Broncos!).

Between 1989 and 1992, Ford made a 2wd F350 Ambulance Prepped truck. This truck had a 50% larger passenger drag link and TRE, which were prone to bending in the light duty applications. The Drivers side link and TRE's were the same between the Rangers, Broncos, and all pickups. This beefier linkage was also used in 1993-1996 F250-F350's, which is why its common to see the inverted-y setup on the "mono-beam" F350's.

These links are direct bolt in and instant beef for ~$10-15 more.

If you really want to flatten out the linkage to try to improve handling, ream the top of the knuckle and make the linkage "Knuckle Under." This flattens out the linkage and gives you ~2" more clearance, keeping the linkage away from the rocks.
