Wintek Suspension Cartridges: The Industry Standard for Reliable Performance

One notorious problem with truck air-ride cabs is a phenomenon called "cabin hop" or "porpoising." At certain speeds, the cab’s air springs and shocks resonate, causing the entire cab to bounce rhythmically. The Wintek cartridge’s progressive valving interrupts this resonance frequency. It provides just enough low-speed resistance to kill the oscillation without making the ride harsh. wintek suspension cartridge
