Update on the Rattle Wagon Suspension.
ACCUAIR is an interesting company to deal with. On one hand they state that any modification of their system voids all warrantees, and on the other they are willing to replace a bag at no cost to include overnight shipping.
Baseline suspension is a Clayton 3.5 lift. Add to that the ACCUAIR Diesel specific 4 inch lift. Right out of the box there is a fitment issue with the front air springs. The factory bump stop is not removable AND requires to be cut down by almost 2 inches for the air Spring to fit in the pocket correctly. The Air spring as I am told has it's own internal bump stop. This become an issue later.
Trying to get the system as installed level at each setting proved to be rather difficult as the ACCUAIR control arms bind due to not having a good flexible joint on the ends. The typical rubber bushing works well for road use and in short travel suspensions but when this one is flexed the bushings tend to bind the suspension up.
Off roading I found up travel in the front to be a problem. Running BFG 39s the tires rub at full stuff. Great for articulation bad for the tire. Normally this would require a bump stop adjustment.... no can do as the bump stop in this kit is internal the Air Spring. The tires touch the fender and trimming is an easy solution. the tires also run the body internal framework not such an easy trimming solution.
Future evolutions will include switching back to the Clayton control arms and making a tab for the ride height control to link to mount to. The rod ends will allow for articulation much better than the Rubber bush end on the Accuair system.
The Air port to air up tires and whatever is very slow to air up 4 big off road tires a second compressor or a bigger single compressor would be much better.
Broken air spring. Amazed at the amount of water within the spring. There is no air dryer in this system, this might be an issue when winter comes. Now I am looking at how to install an air dryer into this system.
Ride quality, Front springs work very well and the spring rate is great providing for a very controlled and smooth ride. The rear, another story there is a tendency to bounce as if the spring rate is not quite enough. I realize air solves this issue btu that also increases ride height. Looking into upgrade shock from them to help adjust compression and rebound.
Off road..... Front flex is an issue. The suspension easily out flexes the ride height sensor calibration and causes an error code on the control pad. When this first happened I thought I broke a sensor. A simple restart cleared the error. Need to look at how to clear this error without a restart. Ride quality is much nicer that the coil over system I had before. But that was also adjustable.
Overall I give this system a 7 out of 10. Great for road work and light off roading or light modifications harder stuff I think I would have gone a different way.
