Slappy Trucks ST1 Curb Killer II Hollow Inverted Black 10.0 (Sold as Pair)

The Slappy Trucks ST1 Curb Killer II Hollow Inverted Black 10.0 (Sold as Pair) brings together innovative truck geometry, lightweight construction, and a signature graphic with a direct connection to the STIX SGV skateboarding community. Built for skaters who appreciate responsive turning, maximum grind clearance, and the freedom to skate everything from curbs and ledges to pools and transition, these trucks deliver the performance-driven design that has made Slappy a respected name among skateboarders who prefer equipment built with actual street skating in mind.

Finished in matte black, the ST1 Curb Killer II features a clean, understated aluminum hanger and matching baseplate, contrasted by exposed silver axle ends, axle nuts, and kingpin hardware. The hanger has a smooth, rounded profile with a wide grinding surface, while the strategically shaped baseplate and pivot area provide additional clearance during grinds and slides. The truck's angular supports, recessed hardware, and open space beneath the hanger give it a distinctive silhouette that balances strength with functional design.

One of the standout features is the inverted hollow kingpin, which sits recessed into the hanger rather than extending upward like a traditional kingpin. This design helps eliminate the exposed hardware that can catch during smith grinds, feebles, and other tricks where kingpin clearance matters. The hollow construction also reduces unnecessary weight, while the inverted configuration allows skaters to approach obstacles with less concern about snagging their kingpin on concrete or coping.

The ST1 truck geometry is designed to provide quick, responsive turning without requiring a lengthy break-in period. Its carefully engineered pivot and bushing arrangement allows the trucks to respond naturally to changes in pressure, whether you're carving through a bowl, setting up for a technical ledge trick, or locking into a long curb grind. The design also emphasizes reduced wheel bite, helping riders maintain control during deep turns and aggressive skating. Contrasting white bushings with silver washers add a subtle visual detail against the all-black truck body.

What makes this particular edition especially meaningful to us is its connection to Ira, a longtime friend of the shop and a rider representing STIX SGV. These are Ira's signature Slappy trucks, making them more than another piece of hardware on our shelves. The custom graphic features aggressive red lettering reading "CURB KILLER", accompanied by a hockey-mask-inspired character with a dark, slasher-film aesthetic. Printed directly across the black hanger, the artwork gives the trucks a personal identity while maintaining the clean appearance of the matte black finish. Supporting riders who have been part of our local scene is something we've always valued, and having Ira's signature trucks available at STIX makes this release particularly special.

Behind Slappy Trucks is Mike Sinclair, a longtime skateboard industry veteran and former professional skateboarder whose experience as a team manager and industry figure helped shape his understanding of what skateboarders actually need from their trucks. Slappy was developed around a straightforward idea: create trucks with exceptional grinding clearance, responsive turning, and practical geometry without sacrificing the feel that experienced skateboarders expect. The brand's emphasis on functional design and real-world skateboarding has helped establish its identity within the independent skateboarding community.

The 10.0-inch configuration is designed for riders building wider skateboard setups, including shaped decks, old-school boards, and larger modern street or transition boards. The wider platform provides a suitable foundation for skaters who prefer additional width beneath their feet, particularly when approaching coping, carving through bowls, or skating wider deck shapes. Choosing trucks that closely match the width of your skateboard is important for achieving a balanced setup.

The combination of matte black aluminum hangers and baseplates, inverted hollow kingpins, responsive turning geometry, reduced wheel-bite design, and signature Curb Killer artwork makes these trucks a distinctive choice for skaters who want both performance and character. Designed for immediate responsiveness without an extended break-in period, the ST1 Curb Killer II offers a familiar feel with modern refinements aimed at improving the overall skating experience.

Around the San Gabriel Valley, from the curbs and street spots of Monrovia and Arcadia to the parks and transition found around Pasadena, Glendora, Claremont, and South Pasadena, Slappy trucks fit naturally into the kind of skating our community has always appreciated. There's something particularly fitting about carrying a signature model connected to one of our own riders, especially from a company that places so much emphasis on grinding, turning, and simply enjoying the act of skateboarding.

Sold as a pair, the Slappy ST1 Curb Killer II Hollow Inverted Black 10.0 trucks provide two matching trucks for a complete skateboard setup. Their functional design, signature detailing, and connection to Ira make them a solid addition to the STIX SGV selection, whether you're setting up a new wide deck or replacing the trucks on a board that's already seen plenty of curb sessions.
