Will A Durango Steering Box In My Laredo?

I did a search, and all the Jeeps that were doing this mod, they all had V8 Jeeps.


So my question, will a 99 V8 Durango Steering box not work in my I6 Laredo?


If `it does fit, at the same time should I upgrade my pitman arm? If so, what brand should I get?

I did read that the V8 Jeeps, they Durango steering box was a direct bolt on with no drillign required. Hopfully the steering box will fit my I6 with no drilling as well.


Thanks for the help!

I can't seem to find any 4.0 ZJ write ups either, but I did find plenty of XJ and wrangler guys that do the swap, that and I'm about 95% sure that the frame rail and mounting is the same between the I6 and V8. You should be good to go.

Yeah all I saw was ZJ-V8s. Didn't see any XJ or Wrangler threads.

That's what I am not sure, if the frame rail is the same.

What is a popular aftermarket pitman arm to run as well?

No, its the wagoneer box that has 4 mounting holes, but the three are the same so you just mount it and drill the fourth.

From what I have read in the past, most use the ZJ pitman arm on the durango box.

The Durango steering box has a slightly better steering ratio, so it turn the tires more for the same amount of turns of the steering wheel verse the stock box, its also said to be a little stronger, has an easier time turning larger tires as the stock Durango tires are 31". Some people will tell you its gives you a better turning radius, but thats not true, turning radius had nothing to do with the steering box.

Should fit fine. Don't get one with the snow plow set up.

There is a difference between the 2 models of Durango steering gear.

The gear with the snow plow package is from my research a 14:1 steering ratio.
(more turns of the steering wheel as compared to the stock ZJ steering gear)

The non snow plow Durango steering gear is 12.7:1. (same ratio as the stock ZJ gear)

The only and i stress only advantage to the Durango steering gear is the fact the hydraulic piston in the gear is larger than the hydraulic piston in the stock ZJ steering gear allowing for a more powerful assist for those running larger tires.

Don't waste your money or time.
I went through twodurango before I figured it out. They don't have as much travel as a jeep box. After the first box I realized the box was getting over extended and adjusted my turn stops all the way out with no luck. The steering box center also doesn't match the steering sector shaft center. So if you adjust the drag link to center your steering wheel it will have 1.25 turns right and 1.75 turns to lock left. I also think this is part of why I had problems. Stick with a jeep box

If you are going to spend some money then look into AGR or PSC.

I've been using Durango boxes on both my TJ and ZJ. All the ZJ's use the same box - V8 and I6 are the same. I've found that the quality of the re-manufactured boxes is far from perfect. The turning ratios vary, the lock to lock turns vary, and some have quite a bit of slop in them. If you go this route, be prepared to take it back if you don't like something about it. Odds are the next one will be different. I had to swap one out three times once to get a good one. The only reason that I still use one is that the original one I bought came with a lifetime warranty, so swapping them out only costs me some fluid.
