Watson SL-1000/1100-LP/LR/LW/RO/SR/SSR, SL-1800/1800-SR Self Steer Auxiliary Truck Suspension.
CONVOLUTED PARTS
Axles that work over uneven ground need springs with long travel, and the ContiTech Suspension Air Spring Kit is a triple convoluted air spring. The ContiTech 64648 folds in three stages, which gives the axle more stroke than a single or double bellows. Long stroke helps the wheel follow the road while the frame stays steadier. That travel matters on rough haul roads, lot yards and job sites, where wheels drop away from the frame often.
