Does anyone have actual measurements on how much drop you get with 4" springs and 1-1/2" shackles. Will it be 5 1/2" or a little less? Thanks in advance.

No measurements but pictures. I dropped the rear with 4" drop leafs and shackles (1" or 2" positions). I could only get 1" from the shackle because the leaf made contact with the bed when in the 2" drop position. Here are some before and after pics.

since the shackle is at the very back,you generally dont get the advertised drop amount

I would say if your leafs give you the exact 4" the the shackle should get you 3/4 to an inch more.

nicolas72gmc · 11-22-2008, 06:23 AM

Thanks guys,

that is what I will do then. I will use the 2.5" spindles, 1" front coils. In the back use the 4" leafs and 1" position on the shackles for a 3.5/5 drop.

xmitsu10 is that what you ended up doing? Yours looks just like I want mine to sit.

please take before and after measurements so you can determine your actual drop,lots of guys dont do the initial measurement so they are guessing what drop they have.

I see it everyday,guys with a 2-4 drop claiming a 3-5 and such.....the numbers game is silly.I have actually installed an exact 2-4 kit on a guys truck and made sure the rear shackle was in the 4" setting also and not in the 4.5 setting,my before measurments and after measurements proved an exact 2-4 drop.......once he got home and placed pictures and info on his forums of choice the truck all the sudden had a 3.5- 5.5 drop.

nicolas72gmc · 11-22-2008, 09:31 AM

yeah I agree. Mine is pretty easy, I'm setting at 32" in the front and 34" at the back. That is center of wheel opening to the ground. thanks a million.!!!

You got it right nicolas, 2.5" spindles and 1" drop spring up front. I just measured the center of the wheel opening to ground and it's 26 3/4" up front and 29" out back. Tires are 255/60/15 front and 275/60/15 rear so the front tire aspect ratio is lower than the rear. It's about 22 degrees outside now so I am sure my tire pressure is a little lower than it should be today, hence it may be sitting lower a bit than it normally would. Sorry I wasn't smart enough to take the same measurements before I dropped it last year.
