    AFCO 3870BG Details

    The Big Gun Double Adjustabe T2 Twin Tube shocks are specifically valved for high horsepower applications. Both small tire and big tire cars can better control the “hit” to the tire with this series of shocks. Don’t “drive thru” your shocks with that big power — choose this series of shocks for the ultimate control off the line. Mount the shock upside-down for easier access to the rebound adjuster.

    • Double Adjustable - broad range of adjustment
    • Big Gun Valving - specifically valved for high horsepower applications
    • Great for BIG or SMALL tire door slammers
    • Shock of choice for 4-Link Dragsters
    • Large piston provides superior launch stability
