    Seismic’s Defcon ultra-high-rebound urethane has a remarkable set of unique and highly-advanced properties – and now we’ve applied it to bushings! Defcon is the fastest wheel formula in the history of skateboard racing – credited with virtually every significant world distance and speed record, including the official Guinness Standup mark. (Pete Connolly, 91.17 mph / 146.73 kph – Sept. 16, 2017, at The Top Speed Challenge in Quebec, Canada.)

    A major step forward in bushing performance…
    Deeper lean and truer, more fluid steering with less lateral hanger slop!
    Highly-energetic yet smooth and controlled return-to-center
    Larger compression range compared to other bushing formulas in the same duro – No premature packing • Fuller wheel contact (less “outside wheel lift”)
    • Smoother, more linear resistance profileConsistent feel • Advanced control

    Fine-tuned dimensions for high-performance fit!
    Full 1.0-inch Outer Diameter optimizes seating in finer Hanger bushing pockets.
    • Inner Diameter carefully calibrated for snug fit on standard Kingpin shafts.
    • Mold-top ends machined for exact height and superior flatness. – No “dished” end surfaces.
    • Two precision-fit heights…
    Medium 0.65-inch (16.5mm): Optimal height for most modern longboard trucks. May fit and perform best without bottom / boardside washer (usually not needed).
    Tall 0.75-inch (19mm): Optimal height for most specialty race trucks. May fit and perform best without bottom / boardside washer (usually not needed).

    Note: May feel slightly softer than comparable duros in other bushings. For optimal bushing performance, do not under-tighten or over-tighten kingpin nuts. Replace bushings that show signs of excessive wear, weathering, or aging.
