Is any other steering box Direct bolt in to an xj?
an if so which swap is best?

 

Dodge durango box is the best upgrade without spending serious cash. Not sure wich years I beleive its a 99 box that fits. Just search for a write up.

 

Yep not sure which year for the Durango box but it offers better steering response and less effort to turn larger tires.

 

Any Saginaw box with the flanges on the driver side will work. Some boxes have three bolt mountings and some four. Either will work. The Durango V8 box has a larger piston in the box so is capable of pushing harder on the pitman arm. If you do this upgrade, you should also brace your box or plate the sub frame so you don't pull the mounting bots through.

I'm pretty sure the procedure is the same for an XJ

 

yj boxes
waggy boxes
j20 boxes

i dont know the benefits offhand

but all of those are considered upgrades

 

Chev S-10 box is the way to go.
Durango has brass bushings, S-10 has dual ball bearings, and is more powerfull. Definately brace the unibody, and start thinking about 1-ton steering.

 

I heard you need an adapter plate for the durango box.

 

i herd stories of people using the k5 blazer box

 

an what year s10 box? An is that direct bolt in also? I will have to drill an tap it either way. my mounting bolts are 9/16

 

Pre 96 for sure. Not sure about later models. No drilling needed.
