Topic: linkage for rear springs

[Makohon]

ok i came up of this nifty idea for the rear shackle linkage, running a hiem joint so the shackle mount/springs ect... have less stress and i get more flex... i cant think of n e thing bad about this set up but what do you think?? what are the bad things about running this setup?? how do you think it will behave on the road?? thanx much!!!

First of all the heim would need a solid place to mount and when i say that i mean you would need to thread it into a solid piece of steel and then weld that in side of the frame. and also the heim is not wide enough to fit in between the shackle unless you put some sort of spacers in between the heims to make them fit tightly together (assuming that you put like three next to each other)  and when you look at the lbs ratings it is for the static radial load capacity not the horiziontial load capacity. they would simply break off over a very short ammount of time.

What would happen to the shackle @ full droop? It looks like it might hit the frame. what about putting the hiem on the under side of the frame?   you would need heavy hiem to handle the side load. might cost more than johnny joints?

I have a full price sheet but it is 25.3 mb so i cant upload it


And it does look like it would hit the frame at full drop

well the pic is just a rough picture and is not exactly what it would look like....  also yes i am planning on using large hiems, i was thinking the size hiems that are on i think the Rock Ready suspension lifts for jeeps... very large hiems.... why not use jonny joints?? well i just like to do my own designs, have never seen anyone use this design but have seen many use jonny joints ect...!! everyone has a yota!! it is very popular so why not when ur building it up make it not like everyone elses, kinda like how im using d70 rear and d60 front on my rig, just dont want to do the same old stuff u see on almost every rig!! well more feedback would be appreciated!! thanx guys!!!

and yes mike d you would need to beef up the rear of the frame to make this last a trip down the block of course and yes i would end up fabbing spacers for the hiem, was thinking 1/4 inch steel to beef up the frame.... dont need n e help on how to fab it up!! just need ideas on how it will perform and how the hiem will hold up... remember i am planning on using  LARGE hiems... not the size u would use for steering!!! later!!!

here is the heavy duty ness you would need to support the horiziontial force.

and do not get anything with teflon or plastic or any of that nylon races crap you need to get a steel ball with a steel race

thanx dude!!

Ummm they already make that setup basically.  You can buy johnny joint shackles and hangers from many vendors in the 4x world.

WT Guess u didnt read this!! ''why not use jonny joints?? well i just like to do my own designs, have never seen anyone use this design but have seen many use jonny joints ect...!! everyone has a yota!! it is very popular so why not when ur building it up make it not like everyone elses, kinda like how im using d70 rear and d60 front on my rig, just dont want to do the same old stuff u see on almost every rig!!"

ummm

Ok if you want to be different do what Ive been thinking on for the last few years but havent done.  Mount the shackle to a (1550+) u-joint.  It would have the best features of all as greasability is concerned and it would have almost 140 degrees of twist if you did it correctly.  hows that for different??

[Makohon [OP]]

that is actually a pretty interesting idea..  dont see how you would get the side to side movement as using a heim or a jonny joint but interesting

[WHITE_TRASH]

If I were doing it I would weld the driveline tube end to the bottom of the frame and attach the spring shackle to the yoke side so it would have bothe fore and aft movement from the shackle end and side to side from the frame end.

Mine flexes just fine with a few leaves out and rears up front.  I try to keep away from any real funky stuff as I don't want to be left stranded in the middle of nowhere.  If it's a buggy or something for show, thats fine.  If you run trails, it's just one more thing that can go wrong.  I've seen broken buggy leafs, busted rod ends and no spares, and broken revolvers.  I don't mind helping a guy out on the trail, but when I have to let some guy have some of my emergency fix stuff never to be seen again, it might leave me stranded.
