How do I need to do a SOA Lift

[Bean]

First off i just want to say i don't have a clue on how to do a soa on my 79 cherokee.I currently have 4in skyjacker springs in the front and 4in blocks in the back and a 3in boby lift.What i want to do is put some 35's on it and a soa on the front. But that leaves me with many qustions
1.Don't have a clue on how to get the correct angle on the front.
2.What do i need to do about the steering?
3.What do i need to do to get rid of the blocks in the rear?

Any info will help. BTW How can i post a pic of her?

Well... before you even start, you need to do some purchasing of 4" Skyjacker rear springs... do away with the blocks as you won't be able to use them anyway.

if you SOA the front... 35's will look like donuts...I have 39.5's on my 4" Skyjacker springs with 3" bodylift and 7" SOA... I have room ;)

You will need to install high X-over steering....to correct your severe draglink angle.

You will need to angle up the front diff about 3 degrees from OEM specs OR put it in a direct centerline to the T-case and cut/rotate the knuckles back to factory specs for best results.

With your front diff in either position, you will need a high angle CV shaft for the front (just to get it operational) and a CV added to the rear shaft to cancel vibes.

Gears will be an issue now or later, but you will need to regear for the big tires... I run 4.89's.

brakeline extensions, shock relocation, diff vent tubes all have to be modified

I have alot of this info on my website (Link in sig below) check it out...may answer alot of your quesitons... :D

WOW!!! Thanks RB!! Looks like i'll be spending some major cash! Anyone know someone that can do this in Western Kentucky (Near Hopkins Co). Any other suggestions on how i could fit 35's on it?

[River Beast]

Fi you only want 35's....(since you already have the 3" bodylift)go with stock springs with 2.5" Rancho Add-a-leafs and do the SOA...in this setup you can get away with just a 4" drop piman arm for steering with slight bump steer present. You can then just weld the new perches parallel to the OEM perches and extend your brakelines, longer shocks and then the driveshafts

This is what I am running and it works out great for me so far.

Cool!! Thanks RB and Porkchop!! That sounds like something that i can handle.

What is the best way to make the perches? Should i just use some channel that is the same width as my springs or is there anything better you guys use? Also who has the best price on a 4in drop piman arm?

[porkchop]

I bought my spring perches from a local spring shop for $25. You can find them in a lot of Off-Road mags too. The channel will work also, with alot of grinding and cutting. I bought my 4" drop pitman from Skyjacker for around $65.

bean,do you have a narrow track or wide track?if you have a widetrack just get 4in.big dicks(these are a manufacter) rear 4in. springs to get rid of the blocks and you should have room and dont worry about the spring over,OR get rid of your lift springs and go with just the spring over and your 3in body lift,that allown will give you 9 to 10 inches of lift.modify your steering acordingly.either way i believe you would have room for 35's.if this isnt right someone correct me but that would be 7in.using the first option and 9 to 10 in.using the second option.bounce this off someone fist to make sure its corect.

FYI: For good, stout perches. Go to Summitracing.com and search for part DCC-4120074. They're a Mopar Performance perch for $13.00/pair. Used them on my CJ spring over. Cheap and strong.

I have yet to find anyone who makes spring perches that will fit on the front D44 housing where the diff is. When I did the SOA on my '78 I purchased some 2" id Channel stock from a welding shop and had them saw it lengthwise. Then I took a carpentry tool (Can't remember the name) that has steel wires laying flat. This tool is for transferring moulding patterns, but will also transfer the pattern of your axle so that you can trace it on the channel stock. Then cut with electric sabre saw using hacksaw bit. This method only cost me ten dollars in channel stock. Also by using slightly longer channel stock then you will get with prefab spring perches I was able to limit axle wrap. Just my .02 worth! :D
