    KYB KG4550 Details

    The KYB Gas-a-Just monotube shock has two possible purposes.  First, it's a direct OE replacement if your vehicle came with a monotube.  Second, the Gas-a-Just is also performance upgrade for vehicles that came factory direct with a twin tube.  It can also increase steering responsiveness by as much as 30%.  The monotube design never experiences shock fade and the high gas pressure can automatically add performance for more aggressive driving conditions or for heavier loads.

    • The correct replacement for monotube equipped vehicles
    • A performance upgrade for twin-tube equipped vehicles
    • The monotube design is more responsive and automatically adjusts to driving conditions
    • Provides a firmer ride and additional control
    • Extended Length: 13.54"
    • Compressed Length: 9.25"
    • Stroke: 4.29"
    • Position: Front

    Hi: This shock is supposed to fit 57 chevy car, but extended length is 13 inches and my stock shock is about 22 inches extended. Is it a misprint or do you have a shock to fit stock 57 Chevy car?
