This is the shackle you have been waiting for and it's sofeature packed for such a simple product! These will work with stock springs and all other aftermarket springs. Whether youneed to replace your tired stock shackle or you just need a little more lift, this bolt in upgrade will do the trick. WHY BOOMERANG?
The boomerang design is important to the function of your suspension as well as longevity of critical suspension components. Many stock or aftermarket lift shackles will "bottom out" on the back of their uniframe mount when coupledto longer aftermarket springs. Their straight design works well for added lift, but not always the best for crawling and acheiving maximum suspension articulation. "Boomerang"refers to the general shape of the shackle. This shape was purposefully designed into IRO's shackles to allow yoursuspension to travel further without the binding up on youruniframe. This simple design feature can also increase the longevity of your leaf springs by not overloading them onthe compression stage of the suspension cycle.
