most of the kits out there are not for our trucks, state a couple times.
they are designed for the hemi trucks there springs and such run a lighter sprign rate, hence the reason I was asked to start or to try to do front springs for our trucks, hence the result is of what you asked for , its an xtreme drop, with a stiffer oem spring.
on the front you must elongate the upper control arm mounts, and you must cut off the oem bumpstop and install an aftermarket one.
on the rear, it really gets fun, a bolt on flip kit doesnt work well on our trucks due to the hp and wieght. I had four or five guys stating that it would eventually bend and wrap up the rear axle, causing major damage, thats why we came up with the combination of belltech parts.
it welds on, that way you get a concrete mount on the axle , not somehting bolted on.
on hte rear you must change the shocks or use shock extenders, on the bumpstop you need to remove the rear bumpstop the oem one, and use a mount that moves it to just outside the frame and higher than the oem or cut the oem one down to almost nothing.
after messing with these things for so long I have decided they aint 1500 hemis 2500 hemis or 3500 hemis, they are a parts bin conglameration of SRT-10 parts, they are there own.
if you want to do a simple drop i suggest shackles, , remove the overload spring, and using the simple rate small air bags for a touch of support,
that way you keep the oem ride, and dont hurt anything, and caltracs are almost a must unless you are going just for the show set up, and not worried about performance
