Rear blocks under my leafs.

I know this is a stupid question, but I have blocks in the rear and I want to get rid of them. If I but shackles for my leafs will that eliminate the blocks?

Generally yes. If you have 1.5" blocks, remove the blocks, and put in 1.5" lift shackles you will end up with the same amount of lift.

That what I wanted to hear. thanks man.

Not so much - I've read from a few vendors about how you get half of the additional length of the shackle as lift, so make sure that's what you're reading.

If you get a shackle 3" longer, that will net you 1.5" of lift. If it's a 1.5" longer shackle, you'll only get 0.75" of lift.

Check with the manufacturer to determine whether the given length is the additional length of the shackle, or the actual lift offered by the shackle after installation.

^^ Correct, it matters. Truth is that as the axle is not centered on the spring, a shackle that is 3" longer than stock will deliver less than 1.5" of lift. I would bore you with the math, but just go look for yourself. The axle is set forward of center. What would be handy to know is where are you now for overall lift. Replacement springs will be the best solution.

that and if you set it up to flex the shackle will not be straight up and down anyway. But if you are playing with shackle angle you likely have shackle relocation brackets which will give you some lift in and of themselves. Lots of things to consider.
