Comfort Ride shock absorber and slipper leaf spring systems will significantly reduce the cause of these common symptoms:
Chucking - the truck is rocked forward and aft when the trailer goes over uneven pavement (dips, frost heaves, and the infamous bridge expansion joints)
Axle roll-up - during braking, the trailer's rear tires are lifted enough to cause a loss in traction (and a rise in the driver's blood pressure)
Suspension rebound - when one tire goes over an obstacle, the trailer tips sideways. After the tire clears the obstacle, the leaf springs (and the trailer with them) rebound like a pogo stick.
Comfort Ride shock absorber and slipper leaf spring kits can be purchased and installed separately, but in combination, the whole is greater than the parts - the two components provide a more significant improvement in ride quality.
