Ray Woo installs the AirLift Rear Air Suspension
By, Ray Woo
Rear Air Suspension
JeepThing now sits level, regardless of load. With the bags at the minimum 5 psi the ride is unchanged from before. With the bags pumped to the maximum recommended pressure of 35 psi the rear-end gains up to 2" of additional height within 30 seconds. Deflating the bags takes 15 seconds.
Theoretically, the simpler kit that connects both bags together with a T-fitting would also give some individual airbag action. As one wheel is pushed up into the wheelwell the pressure between the bags should equalize - pushing the opposite wheel harder into the ground. I cannot vouch as to whether this truly works in a trail situation, nor do I know how fast this would happen given the small caliber of the airhoses. I went with the dual setup because I know it will work, and because of the ever-important "Drool Factor"!
The addition of the airbags does not significantly affect the RTI due to the compressability of the bags and the lack of a bumpstop. The bag still bulges slightly between each coil, preventing the coils from touching one another. However, in the original configuration the coils were similarly limited due to the length of the original bumpstop.
How does it do on the ramp? The bag on the droop side of the axle was inflated to 35 psi, and the compressed bag was deflated to 5 psi. Here are some pictures of JeepThing maxing out the 20 degree ramp at the Jacksonville 4 Wheel Parts Wholesalers- the opposite tire was hitting the curb preventing further progress. That's a score of 1140, folks.
I'm happy and completely satisfied with the kit. Now off to the rocks!
