My cr@ppy slipper spring suspension rides hard and tends to eat the hangers (due to chafing of the springs). I just now was reading about the nifty TASS Gen 3 independent suspension that comes on Adventure Trailers's off road trailers.

"TASS Generation 3: In 2007 we found a promising product that would eventually become the third generation of TASS. The design involved refining the way that the airbag and shock absorber worked together.

The Airshock consists of two parts, a short adjustable shock absorber, and an air bag. Both the components are adjustable, the airbag by inflating or deflating with air, and the shock absorber by changing the valving with an external dial.

The beauty of the system is in combining the two by placing the shock up through the center of the bag. In this combination the shock absorber is closer to vertical, allowing it to work more efficiently, while the airbag works efficiently responding to variations in the trail as well as maintaining ride height.

The Airshock has 16 adjustments for compression and extension that improve the ride quality.

So it would appear that after seven years of working toward the “perfect” lightweight trailer suspension Adventure Trailers is getting close. By incorporating the airshock as part of our trailing arm suspension system we have developed a suspension system that is light weight, extremely quick in responding to changes in terrain, transmits little of the road noise to the trailer, does not have the side to side rocking of a solid axle, maintains travel, is fully adjustable for load, and gives little or no feedback to the tow vehicle."

"Awarded "Best of Breed" 2008 by the Overland Journal........"It was immediately clear Mario had nailed the suspension. Compliance was phenomenal, and he had also added toe-in and camber adjustment to the trailing arms to ensure even better control.""

I emailed them asking if they would sell the suspension as a kit. Until then - can anyone supply me with photos or diagrams of this suspension, as well as the brand and model of their "Airshock"? The two pics above are definitely not very useful. If I could acquire the shocks, I could fabricate the rest easily with a few pics to work from. Tho I would definitely rather install the suspension rather than fabricate a copy completely from scratch....

Thanks.

YIKES indeed! $699 for a pair....

I located the manufacturer - they want $900 for them: Suspension Systems :: ShockWaves :: Universal Styles :: 1000 Series - Universal ShockWaves (Pair) - RideTech.com - Air Suspension Specialist







"Diameter and load capacity:

6.5" diameter SKW1000 series = 2140 lbs. @ 100 psi
8.0" diameter SKW2000 series = 3150 lbs. @ 100 psi

Our latest refinement of the original ShockWave™. It is typically used in an independent front suspension application. It can also be used in some independent rear suspension applications. The ShockWave™ v3.0 uses a double convoluted airspring bellow to achieve the load capacity required for these installations.

Recommended Applications: IFS and/or IRS installations on vehicles weighing 1500-2500 lbs. per axle. NOT recommended for solid axle rear applications..not enough travel, too much load capacity."

I guess this makes Adv Trailer's TASS kit a bargain at $1250, but I would have to haul my trailer 25600 miles round trip to Prescott to have them install it for maybe $1000 more. They won't sell the kit separately, according to the reply to my email.

It looks like I will be sticking with my World War I design rather than their 21st Century design.

Your design follows the KISS principle and out in the boonies that's what I'd want vs a complex system.

I too have slipper springs in my camper.

I took a lot of design ideas from their suspension in the implementation of my air suspension. See my "Mobile Base Camp Build" thread for more details.
