Ok, i hav customary sagging rear end common on most 1st gen runners. What springs do you guys recommend for doing the ZUK mod? I know i have read where 12 to 13 inches is generally what people are using, but as far as brand and where you get them, any suggestions?

I just did the no cut ZUK mod... check out my build thread where I posted the link to the mod write up.

Very happy with the Black Magic Springs (Ebay) 12-inch 120-Lb/inch rating base on above. Had to cut top stop but no problem.

ZUK himself did the work on my 4Runner about 7 or 8 years ago while I had it over at his shop getting a Detroit locker install. I still have the same setup and it works great! I have the 12", 120lb Black Magic Springs

And this setup does not produce too much rake. No need to crank torsion bar. This is on stock 1986 manual tranny 4 Runner.
