lowering of the Quad cab

Allright momma's wanting to lower the QC. We will be towing a 24ft trailer about 7000lbs or better at times. On the hemi QC we used the air bags to help stabalize the load. Now as I see it I have 2 options, on one hand I can go cheap and put coils up front and flip the back, the only problem with this is I don't think the coils will work too well with the added weight of the V-10. But it really shouldn't be that much heavier. On the other hand I could put the spindle on the front and flip the back and I think that would actually be better. I don't want to go to shackles on the rear because I want to use the bags again. And from what I can tell everything is basically the same as a hemi QC, I mean I'm sure the front springs may be different but I suppose the spindles are the same since they didn't lower the QC like they did the RC. Need some input on which way to go.

We are going to be doing a drop on a QC next week. Our initial plan is the do a DJM flip in the rear and cut the front springs. Looking to drop the front 2 in. and the rear 4 in. I am sure it will work and look good. At the same time, I really like the way the stocker rides, so if the lowering does not ride as well, we will put it back to stock. Will post pics when we do and let everyone know about the ride quality.
Just what i have been looking for. Thanks Mr. Hennesy, if you find a good solution i will be doing business w/you.
What's the ride height difference between the Hemi QC and the SRT QC?

Just curious, we were going to lower the Hemi because it was a little too high for me. Sounds like I'll be lowereing the SRT. :)
Bolt the STD cab axle, STD springs, and STD shocks into the rear of the QUAD. The quad will actually sit lower than the STD due to the mounting points of the front spring hanger on the frame. You can leave the rear bar on the STD cab axle, the vehicle actually feels pretty good with it on. Be sure to trim the rear jounce bumpers down about an inch (while keeping the same profile) using a belt sander so that you don't limit jounce travel.

Install the STD cab front knuckles, cut the STD coils down 0.50 - 0.75 inch, and install the STD cab shocks on the front. The STD knuckles allow you to keep similar alignment settings to keep the toe, camber, and caster curves close to stock. You'll also need to trim the lip of the jounce bumper cup off above the flange but below the 'barbs' on the front cups and keep the conical bumpers. Front bar sizes are the same between STD and QUAD.

If you're going to tow with your lowered beast, it would be a good idea to install a set of bags over the rear axle to aid in load capacity. It's important to use STD cab shocks on a lowered quad since the shock bodies are shorter and will prevent a mechanical bottom during hard jounce events.

Might have some pics to share ;)

I've got the bags no problem. But dang I didn't want to replace the whole axle or complete suspension. Wouldn't it be easier just to get a flip kit for the rear that way nothing really changes back there and considering the spindles for the front but I bet the aftermarket wouldn't fit our srt calipers. I'd imagine by std cab, you are talking about the srt ? If not spindles I could just replace or cut the springs, but just wondering about the wieght.
The way I lowered my QC about 2 and 1/4 inches was to hook up my 24 ft Triton 240 LTS bay boat. It leveled the truck out real well. I think this is the best method.
An ol' :D Charger RT will level out a rig as well.
