Rear is sitting on its own...
Front almost but need to get some lugs for the wheels.





Passengerside shock still need to come down about 5-6 inches for full droop

I beleive if i remember right that at the frame its about 26" CL-CL of the joints and at the axle its 8" CL-CL and there about 35" long but i cant remember.

so im guessing thats 25 degrees ? maybe a little more. (reason i was asking) i was mocking mine up this morning and they looked really similar to yours in terms of the amount of triangulation. finding it tough to get to the mythical 40 without really shortening them radically or going to a three point wishbone.

nice build btw

40* of triangulation isnt going to happen in my rig, all i did was angled the lowers 10* and the uppers are to what i can fit with my v8 and such. If i have any issues i will just remove a link and add a track bar. But i think i will be okay..

yea, mine either -

i think overall the shallow angle just puts more stress into the mounts, joints, etc, it isnt that it wont work, its just stressed. its the side loading condition that has an advantage in terms of leverage, the steeper the angle - the greater the force. since most front 4 links end up in proximity to the motor mounts, the third side of the "triangle" has a built in flex or slop factor unlike the rear. maybe, over time that equals a fatigue issue in the frame and mounts or - maybe not.

just an observation -

one other thing to take into consideration is that the lowers are triangulated in the opposite direction as the uppers making it effectively a double triangulated suspension and it has about the same amount of horizontal separation as the rear. I dont see a problem with what he has, if the lowers were straight or the uppers were on less of an angle then there would be a problem with excessive forces on the links....

Good observation though!

Ben, dont start second guessing it!

Alright everyone, heres some update. Be prepaired cause this is a long one..

First off, I've been busy with other things so there isnt a ton of physical updates to the jeep besides flexing and getting some fake bump stop ideas.




^Full droop and flex ( i did both sides just dont need to take double the pics.)

Next I have been debating on what to do with my bump stops. So I have 3 options that i can make them as:

A) Design mount for the bumpstop so that when the axle is at full articulation to either side the stop is full compressed and when the axle is full stuff equally per side the shocks bottom out and does not compress the bumps.

B) Design mount for the bumps so that when the axle is full stuff equally per side that the bumps are also fully compressed but when the axle is full articulated per side that the shock is fully stuffed and not the bump stop.

C) Design the mount for the sweet spot for the 2 positions.

My thoughts:
Obviously you want the bump stop to be in the sweet spot with both situtations. BUT, say trying to do so you have the bump stop mount way outside the frame and it caused major frame twist or to much torque and rips off the mount from the frame.

SO what option would you use if "C" was impossible?

My plans for the jeep is mostly trails, dunes, winter wheeling, VERY little high speed stuff. That being said i wont be blasting threw woops at 70, so the likely hood of the shock full compressing at anything over 10 mph is not likely.


Heres some pics of my thoughts/ designs:















SO whats you opinion?

Ben,

I'd pick your second design, usually the most simple is the best. The others look cooler but the offset from the frame increases the bending moment significantly.

Use the KISS rule!!

Thanks Tab


I understand that the more offset= multiplier for torque compared to it being directly under the frame. I can design it to survive and be strong im just debating on what would be better off; bump stop and shock wise between A and B

I was just talking to Whiterhino about this a couple weeks ago. When I built mine I set the bumps for equal compression. My reason was because even though I planned no high speed runs, Silver lake does throw a nasty dip in sometimes on the flat. I figured with crawling you are moving very slow and the likelyhood of compressing that shock all the way to full compression at 2 mph is very marginal. The last inch in particular is the hardest to compress. Jim said at silver lake he had all 4 tires 18" off the ground at SL and still never compressed the shocks all the way to bottom. Just my .02 Looks good though.

TRJontherox, do you have any pictures of you bump stop mounts such, i went through your build thread and couldnt find any. Thanks

Actually scared the snot out of me when I did it. I hammered it along a stretch that earlier in the day was pretty smooth & it got whooped out really bad. I hit the whoops and realized it would only get worse if I backed off so I just stayed in it. I hopped out after I stopped figuring I had just toasted my brand new shocks & the seal marks showed I had stopped 1/2 - 3/4" short of bottoming out. Ironman was right behind me and said there was at least a foot under all 4 tires.

This is something Bryce had told me would happen that as they get closer to full compression the resistance goes up so high you rarely bottom out.

Alright here are some other pictures for you guys. I got the frame flipped over so i can do some work to the rear frame where i notched it and the front to fit the steering.

And for once the garage is CLEAN Untill i started grinding.


Since everyone else is posting weld pictures, heres mine..


Not to shabby for my first project of heavy welding.

Made my frame sections for the steering at full compression, I still need to add some plate so that will happen this weekend.




And yes I will be cleaning up the edges and so forth so it will look like it meant to be there.
