Slappy Inverted Trucks

The inverted kingpin sits flush with the hanger, which removes the bulky nut that typically hangs off the bottom of standard trucks. This design significantly reduces hang-ups when you are locking into grinds on ledges or rails, allowing for a smoother, more consistent slide.

These trucks feature an 8.25-inch axle width. They are best paired with decks ranging from 8.125 to 8.375 inches wide to ensure the wheels align properly with the edge of your board.

They are designed to be versatile. The inverted kingpin is a major advantage for street skaters hitting ledges and rails, but the stable geometry and responsive turning also make them reliable for transition skating in parks.

Because the kingpin nut is recessed, you will need an Allen key or hex tool to adjust your truck tightness rather than a standard skate tool socket. While it requires a specific tool, the design is generally more durable and less prone to stripping over time.

No, the refined design focuses on reducing weight without sacrificing structural integrity. They are engineered to be lightweight enough for technical maneuvers while remaining strong enough to handle heavy impacts.
