Hey- I'm a new user, drive an '84 Ramcharger Royal SE.
Lookin to do up a 3" body lift. I found a few kits, and they all require that I use a longer steering shaft. What length am I gonna need and where can I get one? Thanks....

 

Borgeson and Flaming River both make shafts. There's no need to figure out the length you need, as they're ajustable. I had a Borgeson on my 90 RC and it was worth every penny (replaces the crappy slip joint coupler that the stock shaft has with a nice u-joint).

Straight from the junkyard parts for this, I used u-joint shaft parts from a Eldorado and welded what was needed together for my frankenplymouth, steering shaft joints also from jeeps. Ma MoPars idea of the plunge joint vs. rag joint still a good thing as body movement issues are not. If yer paranoid about yer welds while ya got it apart you can use a sleeve over yer welds an weld it to both shafts also. Over all length depends on what yer package needs just make it fit!

 

I bought a borgson for my 73 power wagon and its well worth the money and fully adjustable in length
