I plan on making some Shackles I have some 1/4in plate and some 2in tubing

But what I need is a measurement from someone else shackles eye to eye and what lift amount it is (ie stock shackles, 2in shackles ect.)

Currently running teraflex revolver shackles and that's the reason I need measurements from someone else because teraflex doesn't say how much lift is provided..

If I can get a measurement from any size shackle eye to eye I can use that as a reference for where to put my holes.. I plan on making them 1.5, 2, and 2.5 lift adjustable shackles

So if someone told me there 2in lift shackles were 4in eye to eye I'd know I need holes at 3.5 4 and 4.5

Thanks for any help

3" eye to eye is stock

4.5" eye to eye is .75"

6" eye to eye is 1.5" lift

use math to figure out other lengths if you need them

96rokee

So by that math I'd want holes at
6" eye to eye for 1.5" lift
7" eye to eye for 2" lift
And 8" eye to eye for 2.5" lift

i suppose.

i wouldnt go that high with shackles though.

kills your departure angle and will overwork and wear out leaf packs quicker. will give you quite the pinion angle as well (not always a bad thing) you may also have to redo your shock mounts with the rotated pinion angle (if its severe enough) ive never experimented with shackles that long so i wouldnt know.

I'll keep that in mind
Probly only go 1" 1.5" and 2"

Can you explain why it take 2"extra length in the shackles to create 1"of lift?
I'm still struggling to follow that logic but I'm sure if someone explained I cud catch on

ktmracer419

you are lowering the rear leaf mounting point

the front mounting point is staying in the same spot.

the axle is (just about) halfway between those 2 points.

what size tubing would you use?
and where would you find the bushing?

i was thinking bout calling clayton and seeing if they carry the bushings they put in there shackles.

ktmracer419

im making some shorter shackles for my rig now.

you can get the bushings from www.ruffstuffspecialties.com or www.barnes4wd.com as well as other places.

you want a 3" wide bushing and sleeve.

you can use tubing, but i plan on using some 1/4" plate and boxing it all in.

it has to be narrower at the frame side than the leaf side so it doesnt rub the shackle box.

im not finding anything but 2" dom tubing with bushing
both site have those but i cant find 3" wide bushing and sleeve?

oh wait i think i get what you talking about.
you talking about how far the bolt has to go thru the bushing essentially? correct?

it need to be 3in wide and the tubing size and bushing size is semi irrelevant?
or would a bigger bushing be better?

ktmracer419

bigger bushing would allow more deflection/ flex. but the width is what has to be 3 inch. 2" diameter would be fine.

96rokee

awesome thankyou for your help on this!

ktmracer419

made mine today

96rokee

Is that 1/4in or 3/16in?
And did u put that triangle piece on both sides or just one?

Still need to make mine

What did u make yours eye to eye?

Just an FYI, the teraflex revolver shackles do not add any lift
