With most of these trucks getting some miles on them the wandering steering becomes a real issue. We are fully aware of all the options on the market that can help this, but I am here to show you ours.

It is a complete bolt in ZERO modifications needed install. It takes longer to find the right wrenches than it will to do the actual work. These steering shafts get rid of the factory rubber rag joint and replace it with a universal joint. They retain the same slip fit design that the factory uses.

Now some people ask about road vibrations. We have a TON of these on trucks and have had zero complaints about that. Another concern is in the event of a crash the rag joint is made to "Sheer". My answer is always the same, there are many many factory vehicles that came with some sort of universal joint from the factory. We are just simply updating to the better setup.

We offer these for both 88-94 trucks and 95-00 trucks. The 88-94 takes an entire shaft with 2 couplers. The 95-00 only needs the lower piece. You reuse your factory "male" portion and slide it into ours and keep the retention clip in place. It has been noted on our website that if the 95-00 trucks had an aftermarket dorman replacement shaft that upper will NOT fit our lower properly. They made them specific for their own lower it seems like.

Installing a U-joint from a third-party is a pretty easy replacement for the rag joint, e.g.,

- Flaming River FR1746DD Billet-Joint 1"-DD X 3/4"-30 Steering U-Joint

- Borgeson 015231 1" DD x 3/4"-30 Steering U-Joint

- or as applicable

As stated in the first line. Many ways it can be done. I'm only sharing the way that we make a living off of. 99% of our customers don't want to have to modify, cut, grind, weld, whatever the case is. They just want bolt and go

I got the lower shaft u-joint for my Burb. It was the final thing in the front steering and suspension that I replaced.
It does give better feedback and response, but man was it a pain to separate the original upper and lower shaft.
It also took 3 attempts to get the splines to line up correctly; first it was off 2 splines to the left, then 1 spline to the right, the third attempt nailed it and it drove straight again.
