Can anyone tell me how much lift you will get in the back end from putting front CJ springs on the rear of a Samurai. I have read all kind of information about this but no one says how much lift you get. I have a short drive shaft do to the V6 and height is an issue for me.

Thanks
Will

Stock CJ fronts in back gave me about 3" above stock. That's taking into consideration the aftermarket (stronger) shackles I used that gave me at least 1/2" of lift on their own.
You can move the axle back almost an inch before you get close to hitting the gas tank (with the lift). It sounds like you are going to need a custom shaft anyway, so check out the Tom Woods shafts that will allow more angle.
Tom's driveshafts are stronger than most Zooks will ever need. The V6 you mention will appreciate it.

I had about a 1.5" lift from after market 4" shackles, when I purchased my Zuk. I then did a CJ/RUF and gained another 4 to 5" of lift to the rear. I think the variable is the condition of the CJ springs and the amount of arch they have. For the RUF portion, it was lower than the rear. I had to add leafs from the from pack and then have them re-arched to match the height of the rear.

Quick lesson time! What is "RUF"?
Most Zuk owners in my area start with a spring over axle conversion then select their suspension components depending how their going have fun.

All this is great learning "stuff." My 86 tin top awaits its Tbird V6.

'RUF' = Rears Up Front

A common spring lift is to repack a set of rear spring packs (remove the overload and add an extra second leaf from a front pack) and mount them up front. They are a bit longer and will make the ride a little smoother while lifting the rig 1"-2".
Then you mount a set of Jeep CJ front springs (same width as Sammy springs) on the rear of the zook, also smoothing out the ride and giving a bit of lift.

Front CJ leaf springs are 3" longer than the rear Samurai springs. The rear Samurai springs are 3" longer than the front springs. The CJ/RUF will lift the vehicle about 3" and the extra flex provides a smother ride. Some Samurai drivers will use YJ springs front and rear which provised even a softer ride.

My Bad. I just check my original post on Zuwharrie.com. My shackles where 5" not 4" and my CJ/RUF raised my zuk 6" above my 225x75 tires.

All the info is consistent with the voices around me (oh no, i'm hearing voices again). Now I need to consider the weight difference between the Bird motor and trans and the old 1.3. If I'm looking for the smoother ride I wouldn't think stacking too many leaves would be the answer there(?).
Really good directions guys!

Well, it is really quite simple.;) The CJ springs that go on the back are a five pack, but are 3" longer and usually more arched than the flat zuk springs. They are more bowed, raise the vehicle and flex more creating a softer ride.

The stock front zuk springs normally have three leafs. The rear zuk springs moved up front (RUF) are 3" longer than the fronts and when installed are a little more arched. They raise the front and flex more providing a softer ride. The problem is the old zuk springs, front and rear are bacially flat and the height does not normally match the rear. Normally, taking one leaf out of the rear CJ's, or adding one or two leafs from the front usually brings the front height up to match the rear. In my case, I still had to have the fronts re-arched to match the rear height and level the vehicle.

Also, I made my own winch bumper which ended up weighing 120 lbs, plus 8,000 lb winch.

Before my CJ/RUF, my zuk would beat me up. Now it rides pretty darn soft.
