Ndaniels,

I am following your exploits closely!

Just for reference, my truck with the stock tires (LT265/70R17), sits at 34.0" inches front and 36.0" rear at the top of the middle of the wheel wells.
1/2 coil trimmed front coils. Both rear spacers removed from the rear leaves.

The 3rd Gen frame is fully enclosed. It's not a open C-channel like in the out board air bag install instructions.
One would likely have to weld the air bag frame brackets in place.

The instructions don't mention the width of the leaf springs. Be careful with that.

BTW, when I had my air bags, I ran the shrader valves to the fuel filler opening behind the fuel filler door.
The insert is plastic and very easy to drill to install the shrader valves.

I was able to jump out of the truck flip open the fuel filler door and check air bag pressures with a gauge.
Plus with a small 12V air compressor, I could plug it into the 12V socket on the dash and quickly fill up the air bags.

Installing the air bag shrader valves at the back of the truck makes no sense to me.

Hey Stelth, I'll definetly keep you in the loop as figure it out.

Friend of mine with a lowered Chevy does the same thing with his fuel door and the cig lighter air compressor. That works well and is an easy install. I have onboard air for my eb along with a 3 gallon air tank, so I mounted a manual inflator paddle and gauge under my center seat bottom, so I can adjust it from the cab.

I've owned a few second gens, and the springs are the same width, so that should be ok. At this point I'm figuring on welding it to my b&w hitch frame, but will see how this lines up. I found some pictures of an install a guy did on his 4x4 with this kit and he welded it.

So I ordered that kit this past week and figured out how to install it Saturday. Measured everything out and figured that I needed to cut 1" out of one side of the lower bracket to get the angle to match the upper bracket. Oh, and I had to mount the upper at a slight tilt because of the b&w hitch. Figured that I can weld the upper bracket directly to the hitch and not affect frame strength at all.

So today I went up to the farm and had a guy I work with weld it all up for me. I'm a good mechanic but not much for welding. This has to be a lot stronger than Firestone's method of bolting the upper thru the c channel frame on the older trucks. He welded both outside and inside of the bracket. The only thing I really had to modify was cut and weld the park cable bracket to the upper mount on the drivers side.

Clearance could be a factor for bigger wheels and tires but I'll get better measurements and figure up what I can do. This was a lot easier than I expected and I'm really happy with the results. Figure I can sell my old bag setup and sulastics to help offset the cost of the new bags.

I had a chance to try it out towing this past week.

Picked up a material handling fan (2k lbs) with a bumper pull car trailer (another 2k) and loaded it on the nose of the trailer- figured might as well try these bags out. Had to inflate he bags to 40psi to level it, but I was stupid heavy on the hitch for what little weight it was. Made the 3.5hr drive back no problems. Made for a pretty stable ride thru the turns in wv. A section of 35 here in Ohio has horrible concrete and got it into a rhythm that was awful at 73mph and no amount of adjusting the bag pressure would smooth it out- but it's my fault because of all the tongue weight.

One thing I'm going to do is add the mopar finned diff cover. I was suprised the rearend was as warm as it was, but it makes sense since its out of the airflow more now.

First impressions is it looks like this should be a good way for a guy to still tow and be able to go lower in the rear. Still have to hook to the gn and see how it does with more weight.

Awesome. This would be something I would go after.

I'm seeing people are cutting 1/2 -1 coil on the front coils springs, and maybe I missed it, but how much drop is gained by cutting 1/2 coil. 2500? And 3500? Thx in advance.

It's a firestone 2071 kit. http://riderite.com/-/media/www/ride...lManual_EN.pdf

I just modified the lower bracket some to match my spring/top mount angle. Works really good. Towed the gn some with it and was pleased.
