Some lift Q's...

So if you read my earlier post I just got a '74 CJ5 with a 304, D44 up front and a Frod 9" in the rear. I'm planning on putting 33x13.5 LTB's on it. Since I was off today I spent a lot of time on the net researching my options. It seems that I need about a 4" lift to really clear the tires with good flex and that's what I am looking for. I will be in the mud a lot but I also like to play on the rocks and I would like to see some nice flex. With that in mind I have an idea for the suspension and I am looking for advice since I am pretty new to Jeeps (I have a lifted Nissan).

Since I have read that that 1) the smaller the spring lift the better the flex because of the lesser arch of the spring pack and 2) the shackles really give the articulation. So option one would be to get 2.5" Lift Springs and 1.5" shackles (with 4" lift shocks and I assume I need a dropped pitman arm and shims for the driveline angles). I am not opposed to cutting some fender if needed as well but need to keep the jeep street legal. The other option is just to go with a 4" lift (with 4" lift shocks and I assume I need a dropped pitman arm and shims for the driveline angles) and just make it easy. Will the spring/shackle combo really give me better flex than the 4" springs alone?

Not planning on a body lift unless I really need the overall lift to go over 4" which I don't think is needed for 33's.

Also I assume rim backspacing will play a role in rubbing...what is a good BS for this setup?

Thanks,
Tom

 

Tom I've run 4" springs that flex great.
Superlift or Rubicon Express both offer good setups.
Not sure on the back spacing.

 

Does RE offer them for 75 and older?

Not sure, seems like they did though.

 

Just went to RE web site.
They dont list pre '75.
