Ok ,

Well fist off thanks for the props.

I have wanted to build Long arms ever since I got the ZJ, so the design has been well thought out.


I used Johnny joints at the frame end of all the lowers and polyurethane bushings at the axle side. I used custom bushings I had made up for me by a local urethane shop, but any urethane bushings will do (i.e. polyperformance) the only difference is that my poly bushings are in a 1/4" DOM tube sleeve where most companies out there is using 1/8" HREW pipe. Inside the poly bushing is a 1x1/8" wall DOM tube that is a sleeve for the 3/4" bolt that go's through the center. Then I got grade 8 allow 1" fine thread ready rod (6" long for adjustment) and welded nuts on the end then welded the nuts to the bushing/Johnny joint sleeve.

My front arms use 3" Johnny joints, and my rear uses 2-1/2" Johnny joints. All my poly bushings are 3" except the 2 in the front upper arms. They are 1". Everything in my suspension uses 3/4" bolts except the four (4) rear Johnny joints, they use 9/16" bolts.

My arms are 2x2x1/4" wall HSS with 1" fine thread deep nuts welded in the ends. The rod ends thread into that with jam nuts.

My rear upper arms are the same construction in the rear except I used poly bushings at the frame and Johnny joint at the top of the pumpkin.

My front uppers are a radius style (connect to my lower arms) and they are made front 1-1/2 x 1-1/2 x 3/16" HSS with the same style poly bushing at the axle end (these bushings are the same poly but they are only 1" wide, the other ones are 3" wide) and the other end is a 3/4" Teflon heim joint. My front lower arms are triangulated out about 10 degrees

The rear upper arms are triangulated (40 degrees separation) at the top of the pumpkin. The truss that it connects to is constructed from 2x4x3/16" HSS with 5x1/2" flat bar at the top.

The sub frame is 4x6x1/4" HSS cut in half to make the two sub-frame rails. 1/2 for each frame rail. I used the stock cross member but chopped about 5" off each side and welded on a plate so it could be removable from the sub frame yet it would not be in front of the lower arms. This allowed me to run incredibly long front arms. The sub frame is bolted on in three places and then welded at the ends and periodically in the middle.

My front track bar is a modified RE standard adjustable front track bar. I flipped the heim and made a new bracket at the frame.

All my brackets are made from 1/4" plate. Actually the only thing in my whole suspension setup that is not 1/4" or more is the two pieces for my rear truss and my front upper arms.

Arm Length:


Front

Rear

Upper: 40-1/2”
Lower: 38-1/2”
* These are all approximate sizes so give or take ½”.

2. 40" 4x6x1/4" HSS
3. 1/2 4x8x1/4 plate (approx)
4. 48" 3x 0.250 wall DOM tube
3. 48” 1x 0.125 Wall DOM
5. 20" 4x2x3/16" HSS
6. 20” 5x1/2” flat bar
7. 3 @ 36” 1” NS 14 TPI alloy ready rod
8. 14 @ 1” NS 14 TPI grade 8 nuts

10. 8 @ 5” ¾” NF grade 8 bolts plus 2 washers, and 1 locking nut each
11. 4 @ 3” ¾” NF grade 8 bolts plus 2 washers and 1 locking nut each

16. 2 @ 1” poly bushings

My steering has yet to come I will be doing a write up on that with pics and stuff.

that rear tire is 50" above the ground. Roughly a 1300 on a 20* ramp (for you monkey ass bitches that care about RTI ramps, Dave don't deotorize me for posting RTI info! :flipoff2:). you can tell there is mad binding in my front radius arms. the front barley unloads right now. i will be building a telescoping upper arm so that i can disconect it when i go off road. but have it connected on road.

hope you all like.

just IMO, joints at one end or the other would help the front. If you put a telescoping arm on, what's there to keep the axle from rotating?

i will have one fix arm and one telescoping. i have 3/4" heims on one end of both arms. they should flex a bit. but that telescoping arm will help alot.

gotcha. Why not just remove it offroad?

ya too much on-orr work i would rather have a telescoping on with a linch pin or a cam bolt. pull the pin away you go. easy enough for me.

ok this looks nice.. i like how the arms are adj while they are in:) what does the front pass side look like, im having trouble identifying which pic is it... umm thanks for the pics looks great, im assuming it rides just as well.?

the steering/trackbar seems kinda funny. why such a short trackbar?

well the stearing is totaly micky moused together right now. it will soon be 1 ton. and the track bar has to be that short cause to keep the allignment paralelle with the track bar braket. i move the front axle so far forward that it could not mount in front of the axle like befor. i may change it to the rear side of the axle and runn a longer one. but for now i have ZERO bump stear and it rides amazing. straight down the road. doesn't even grab ruts. slight shaking cause i don't have a S/S. no death wobble. it works great.

You might need to do a little bumpstopping back there, damn! Thats nice man, it looks mean as hell. I cant believe the amount of down-travel you have, thats the most Ive ever seen on a ZJ

hmm no bump stops for me just a big old sawzall

thnx,

i got a 3 ton d70 (35 splin, a carrier they actually make gears for and its 67" wide) it all matches the front axle alot better its going to go in after i pass a VI.

the 70 i got in there right now is from a 67 they no longer make gears for it.

cool but it must be a pain having to put your springs back in all the time. really nice work clean to i like it! were did you get that bumper its pretty sweet!

Thanx man, i built the bumpers and my springs no longer fall out i have retaining clips.


everythign you see thats not stock i built. i don't buy stuff that is just steel fab. for some crazy reason i like fabbing stuff
