I see what u are saying. I was curious if I was gonna have to cut out my fenders... hmmm cause I will be running 18's lol might need to finagal the fire wall some. Hmm. This should be fun ;) was contemplating if I wanted to try and do the front cab off or not. Was trying to avoid it. But it might just be easier ti pull it off then fit the cab on afterwards....

Im pretty sure i will be Z'ing the frame 3 inches. that way i can still ride low and not have to be at a low psi and it will be easier to get the front to lay as i hear that the front lower control arms make contact with the frame before it lays. Could prolly get away with a 2" Z but im in there might as well make it worth is haha. Gotta figure out what Im going to do about the steering tho. Anybody swap rack & pinion into their 620? what are ppl using?

nice work on the truck... going to be a huge improvement

 

 

now on my my very very serious two cents.

if you weld the lower links to the axle, then the axle and links will move in unison because they have become one piece.

if you put upper links on that are not the same size, and that dont mount in the same exact place on the frame (making a triangle from side view) then your links will bind and either break, or not move at all...

 

 

please do yourself a favor and either

A. connect upper links to the lower links.

OR

B. cut your saddles on the lower bars and put heim joint on instead.

 

 

 

if you go with A, then your lower bars will have to run just about straight out (from axle to frame)

the upper links should go from center of axle to the lower links midpointish

 

doing this will create three triangles, and keep your axle centered under the truck...

yeah in 4 link situations there gonna be 4 points on contact on the frame and then 4 more on the axle...

 

just make that boxed end have a busing like the other end.. done deal..

 

youll need to make tabs from the axle for the bar to mount to..

 

easy peasy man..

 

heres a pic of my 1st 4 link... not the best, but its still running around...

And why do you prefere it? What benefit does it have doing a 4 link or running a watts. Cause I like the simple and clean look and that setup doesn't get any simpler but I don't wanna comprimese a more effective 4 link for a simple clean 2 link. Is there a name for that setup?

well the diagonal bar or a watts is up to you.. in most cases you dont need alot of side to side support on a 2 link if its built right.

 

that really just there for you to know mechanically it wont move side to side.

 

the main thing i like about the idea is that you have a long arm thats going to only move a short amount, thus, making the availing space to working with a little bit less of a am-i-gonna-have-enough-room moment..

 

theres alot of options on where to put the bag or coilover or spring or what-have-you..

 

my plan was to put my bags behind the axle.. they have 11in extension, so that would be plenty to get it off the ground.

 

another thing that a proper 2 link does is cancel out alot of body roll. if you can image the rear suspension mimics the lid of a box.. theres not alot of twist it allows... con? yeah, but also a pro.. i figured id be able to get away with 4 valves. 2 for front up and down, and the same for the back.. the 4 link guys that run 4 valves get the gangster lean when you only have one big dude drivin..

 

things you have to look out for with the 2 link are the points of stress.. you need to make sure that the pivots for the links are build to take all the twisting force

 

in either case, your gonna be well off.. the idea you had goin for the long bars with the saddles welded to the axle would work pretty well id imagine...

 

and a 4 link will work just as well if not better depending on how its setup..

 

now the big difference between the 2 and the 4 link is going to be a fixed or unfixed axle..

 

the 2 link solidly mounts the axle to a bar and takes almost all the rotation out of the senario..

 

the 4 link gives you the option for articulation, like the pic above with the axle all angled out..

 

from the way it looks youve got the parts to go either way...
