You could always go with a smaller spring lift, bolt in relo's, and see if your current shackles work as far as height. Do you need them, well no, but if you want your shackle at the right angle it's something to invest in. You'll have a better ride and more articulation.

Yeah, they are good to have if your shackle is pulled forward due to cheapo leafsprings being too short. So not sure if you will need them until you instal the lift. Ideally for a 4.5in lift you would need a 3.5in leafpack and a longer shackle though (possibly with no lift relocators if needed). So if you are getting 4.5in leafs naturally there could only be one outcome if you add a taller shackle to the mix.

4.5" leaf packs are used for 6" of lift.
To reach 4.5" lift, the correct way is 3" or 3.5" leaf packs and an extended shackle.
The stock shackle used with these leaf springs will not function properly. Will not allow the leaf pack to articulate.

You figured it out the hard way. 4.5" leaf packs are used for 6" of lift. To reach 4.5" lift, the correct way is 3" or 3.5" leaf packs and an extended shackle. The stock shackle used with these leaf springs will not function properly. Will not allow the leaf pack to articulate.

Taller leaf springs need a longer shackle to function correctly. Add-a-leafs are a different story.

If you have no problem hacking off your spring boxes, go for it. If you do, go for the bolt in style and smaller lift springs. You can always piece your lift together instead of going with a complete kit.

So I could use my extended shackles they're adjustable from 1.5 to 2in so would te bolt in ones work for that?!

Keep the coil spacers in the front I have never heard of them causing problems. I can imagine if you tried to stack a number of them but 1-2" is fine.
Just because things come as a kit doesnt mean it is engineered well or all aspects are built well. You would do yourself a great service if you take the advice of piecing your lift together. For one you want good shocks and the ones in most kits are not very good. Take a look at the parts list from the kit you like and create your own off of it.
Dont get me wrong, there is nothing wrong with using a kit. They get you lifted and tons of folks have gone that route even myself when I started. I just wouldnt do it again that way and if I had taken more time researching I would have done things different.
Best of luck with whichever path you go down. Either way you will likely learn some things and hopefully enjoy the experience.
