Performance

The standout feature of the ST1 Inverted Curb Killer trucks is the recessed inverted hollow kingpin system. By lowering and hiding the kingpin deeper inside the hanger, Slappy improves grind clearance significantly and reduces kingpin hang-ups during grinds on curbs, ledges, rails, and coping.

The hollow axle and hollow kingpin construction reduce overall truck weight while maintaining strength and durability. Riders benefit from:

• Improved stability during technical skating

The truck geometry is designed to deliver responsive turning with minimal break-in time, giving riders a smooth and predictable feel immediately after setup.

• Stable control at higher speeds
• Reduced wheel bite

The wider 9.0” axle width provides extra stability and foot space, making these trucks especially suitable for wider decks, transition skating, bowls, and heavy street setups.

Construction Quality
