I installed a 3" shackle kit from JLP a couple of days ago on my 03 Lightning. I dropped exactly 2". I waited a couple of days to post to see if it would change at all. So at this point the 3" shackle is worth 2" on an 03. It did make the truck almost level, maybe 1/2-3/4" higher in the rear.

2" shackles never give you at true 2" either. You did well to get the full 2.

 

I agree, I wasn't complaining. I've just seen several posts asking how much they would give on an 03 so I posted my results. Like you said, since it only affects one end of the spring it will not drop the truck 3" just because the end is extended that much further upward.

You may pick up another half inch, as some of the HD guys have the JLP 3" shackles, and they seemed to pick up a little after a few miles.

 

I've been wondering: Are 3" shackles named that because they are 3" longer than stock? AND- when installed, only ONE end of the spring is located 3" higher than it was--so you don't really get a 3" overall drop???

 

That's my guess.

 

looks like a stock 99-02 truck now.

The truck looks great. I also checked out your project cars, all I can say is wow.

 

Thanks Don, I appreciate it. I'm just a performance nut. This Lightning is going to be a LOT of fun!

I don't get it. How could a truck "settle" a few days after shackles have been installed? It's steel; it won't stretch anymore. However, I can certainly see how drop springs would settle.

 

anyone seen an 03 with a bell tech 2/4? ? I wanna go 2/4 on my '03 and am wondering what everyone suggests

 

Sonic blue 03's look great! Especially since you got rid of the farm truck look.

 

well, when the shackle push's the leaf spring up and puts more stress on it to make it lower, the "settle" part is just when you drive it, it gets use to the stress so it curves down alittle more.... it's hard to explain i guess but you get the idea?? when you first install the shackle the leaf spring kinda looks like a half oval, than after driving it, it kinda goes to more of a half circle....

 

can someone confirm this??? Or at least give me the total length from center bolt hole to center bolt hole.
