ive got a 3/4 drop and wanna go 1 more inch in rear. can i get a 3 inch shackle? will it bottom out?(04 rcsb 2wd)

 

No there physically isn't enough room under the bed to run a 3" shackle. the problem is that a 3" shackle isn't just 1" taller than a 2" drop shackle. Since you're only changing one mount point of the leaf spring it needs to be taller than that.

You can do one of several things:
-Take out your overload spring
-Run a drop leaf
-Run a flip kit with air shocks

 

What Random said, and i would recomend a notch for anything more than 4" so you dont hit the frame all the time.

 

which is the overload spring?will it ride any different?

 

i have 3 inch springs in the front, 4 inch springs in the back and 2 inch shackles with aftermarket overload springs which makes it about a 3/5 drop. i also have my frame notched.

 

You should have 3 leafs in your leaf pack. The bottom one is much smaller and is used for towing that is the overload. You will notice a slightly bumpier ride.

 

thanks guy, does any one here have this done to there truck

 

tons of people have taken out their overload springs.....good for helping lower the truck but bad if you still use the truck as a truck like i do
