2012 F350 Tow Rig/Daily Driver

Kelderman and airbagit are the only two companies that make them and they are both WAY overpriced in my opinion.

Ill do some calculations to see if the 4 5/8" bolts that hold the two axle brackets together will be strong enough or if i need to wrap them around the axle if that makes sense. I do plan on running a panhard bar but it will have to be behind the axle as now i will be mounting the bags so the center of them is just inside the frame rail. I am thinking of moving my shocks (currently Rancho 9000's) to out side of the frame and have them mount off the lower link bracket. I think this will help dampen each side better.

The good thing with moving the panhard bar to behind the axle is i can lower the mounting point which will lower my roll angle and help with cornering performance.

Ill work on some more 3D modelling tonight and post pictures later.

Thanks guys!

Going to the parallel 4 link will help tremendously with your anti squat and handling issues but it's not going to do anything for the ride quality. The ONLY way I'll run my trucks is with the bags mounted on the lower link bars. You really need to find a way to get your bags on the bars. Even if you have to go with a 6 link just to get the bags on the rear bars.

I run a bolt on four link on my dually and no problems with clamping the brackets around the axle. Mine is made by air ride technologies. Check out there kits for design ideas. I run contitech triple stack bags behind the axle and rides super smooth unloaded and even better with a load. I tow about 12,000 lbs with it no problems at all. I am body dropped on 24's, put my 650lb quad in the bed and tow my 31' 11,000 lb travel trailer with it. I run about 25 psi unloaded and 55psi loaded.

Those seem to be good kits as far as bolt on stuff goes. I've never heard anything bad about them. I'm really just not a fan of running the bags anywhere but on the link bars or on top of the axle. In front of or behind the axle and the weight pushing down will try to twist the axle putting more stress on your end links. If your bags are behind the axle with a good sized load and all that stress trying to twist the axle and than add to it the extra stress of the axle trying to twist backwards when your under acceleration. All of that together is a lot of extra stress on the bushings. Not saying it won't work because it obviously will but if you can avoid it why not and take that stress off the link system.
It's also pretty hard to deny that the best rode quality and the best lift possibility is on the link bars.
Either way will work though. All just a matter of opinion and person preferences
