Topic: Custom Boomerang Shackles?

[rednk1980]

I came up with an idea to solve my problem of moving the rear shackle mount back two inches. I designed a boomerang shackle that takes up for the loss of 2 inches and doesn't move your axle forward any. Let me know what you guys think about this design i need some serious feedback on these to decide wether or not to build these or if im just going to waste my time. I cant extend the frame! So dont ask. Im going to use 3/8 plate to build these out of. I set a diagram up of how the shackle would look at different shackle angles.
Red = 0* meaning no weight on the spring
Blue = 22* IMO the perfect shackle angle with the weight of the rig on it and broken in
Green = 45* I think this is completely flexed out but probable wrong.

Or you could just buy them.
If you have the resources to build them then do it.

Yeah i thought about that but do they make them to where the eye is two inches back.

I don't understand what you are gaining? You will still have the same shackle angle, but it will just look differant. The only thing you gain is clearance, like on the front when you have a body mount that limits travel. I don't think the lines you have drawn to give your shackle angle are correct either. I am no engineer so I could be wrong. You will only fool yourself into thinking your shackle angle is differant. I have added the lines that are correct. Your red line will not happen with no weight on the spring. The bend is irrelevent, the angle will only travel in a straight line. Look at my boomerang shackles with no weight and notice how they act. That should clear things up.

i agree with alwaysbroken. its just an illusion i think. the metal is just cut in a different shape but the angle is still the same no matter what. its understandable what your trying to accomplish though. i have to move mine back like 2" as well.

ahhh i see now thanks guys now i just have to start from square one again.

Just get longer shackles. The longer shackle will make your angle more vertical. You will get a lot more drop and not have to relocate the mount.

i was thinking about banana shackles. they look cool function well i think. mc 4 inch springs 4.5 standard shackles, i have no problems. but what i found if you mess with something too much you end up making your build better. 3 years on the same truck. the banana shackles look very interesting though. i might try and make them.
