I just put the FRPP kit on and I dropped a full inch right away.
What do you measure from the ground to the fenderlip in the center of the tire? I am at 31" with stock tires.

 

yeah i too have a 2004 sonic blue lightning and not really sure what to get as a lowering kit for my truck. so far i have the 2 inch belltec shackles....nothing more. id like for the front to drop 1.5 inches and the rear to drop another 1.5 to 2 inches. i was considering the roush kit....but dammit man, thats a grand. i can do the install myself since i work for a lincoln/mercury dealership....but still, a GRAND!!!! lol well, a picture is worth a thousand words.....so start posting pics of your truck(s) ....please thanks.

 

Just to answer a few questions. The only thing in the back is the stock seat, so I don't think that is making a difference.

I put in the 2 inch lowering shackle at first and it only dropped the truck another 1/4-1/2 inch and like you said scv8 I don't want to loose all my rear travel, so I took them out an all I am running now in the rear is the hotchkis rear leafs with stock shackles.

Don, you know me too well, I rolled the truck out to take the pictures and pushed it back in. As soon as the roads dry up I will take it for a run, I was kind of thinking (hoping is more like it) that driving it, might help it settle a little bit more.

I will try and get a brighter picture of it in the warmer months.

04SVTLIGHTNING, I wanted to go with the TVS from hotchkis, but like you said it's a grand! and I need go fast parts before I sink a grand into the suspension stuff.

So what I have is the 1 inch springs in the front and the 2 1/2 lowering leafs in the rear. (on the 04's I believe the drop is more then 2 1/2)

chief40al, I am sitting at 31 3/8 from the ground so let's hope it sinks a bit after some miles..

What should I do with my FRPP 2 inch shackles?

Thanks for all the replies!!

 

John, something you may want to consider is the Hotchkins front springs. After doing research for my own truck recently, I read that they drop a Lightning 1.25-1.5 inches. They seem to be the only front spring that drops our trucks that much without cutting. Just some info for ya.

 

Roush with 2" shackles.

 

the back looks lower than the front.
