Slappy Trucks ST1 Hollow Low Black 8.5 (Sold as Pair)

The Slappy Trucks ST1 Hollow Low Black 8.5 (Sold as Pair) takes Slappy's signature quick-turning geometry and brings it closer to the ground for a more responsive, controlled skateboarding experience. Designed for skaters who want faster pop response, excellent grind clearance, and a lower center of gravity, these trucks combine practical engineering with the straightforward performance that has made Slappy a favorite among street and transition skateboarders. With an 8.5-inch axle width, they're an excellent match for standard 8.5-inch decks and riders who prefer a balanced setup for technical street skating, ledges, curbs, and skateparks.

The design features a natural silver aluminum hanger with a smooth, rounded grinding surface, paired with a contrasting matte black baseplate. The combination gives the trucks a clean, industrial appearance without unnecessary graphics or distractions. Viewed from the side, the hanger's sculpted profile features an open triangular section between the axle and baseplate, providing generous clearance around the kingpin and pivot area. The polished silver axle ends, exposed axle nuts, and recessed hardware complement the darker baseplate, while white bushings and metallic washers add another subtle contrast. The four-hole mounting pattern, reinforced baseplate structure, and compact geometry complete a functional design built around performance.

What separates the ST1 Hollow Low from a traditional skateboard truck is its 50.0mm ride height, compared with the 53.9mm height of the standard Slappy ST1. That nearly 4mm reduction positions the deck closer to the ground, lowering the center of gravity and creating a more immediate response when popping tricks. With less distance between the board and the riding surface, skaters can experience quicker board response during ollies, kickflips, and other technical maneuvers. The lower stance can also contribute to a more planted, stable feeling when approaching obstacles or maintaining speed through a line.

Unlike many low-profile trucks that sacrifice grinding clearance to achieve a lower ride height, the Slappy ST1 Hollow Low maintains the brand's distinctive grind-friendly geometry. Its specially designed hanger and kingpin placement provide additional room for locking into smith grinds, feebles, and other tricks that can expose the limitations of conventional trucks. The result is a low truck that doesn't force skaters to compromise between getting closer to their board and having the clearance needed to skate aggressively.

The hollow kingpin construction reduces unnecessary weight while maintaining the strength required for everyday skating. Combined with Slappy's responsive steering geometry, the trucks are designed to turn naturally without an extended break-in period. The bushings and pivot arrangement deliver quick reactions to changes in pressure, making it easier to initiate turns, adjust positioning before a trick, and maintain control through transitions. Slappy's emphasis on reduced kingpin snagging and improved clearance means fewer interruptions when grinding rough concrete, painted curbs, and metal coping.

Behind Slappy Trucks is Mike Sinclair, a longtime skateboarder, former professional, and respected industry veteran whose years working with professional teams helped shape the company's approach to truck design. Sinclair developed Slappy around the idea that skateboard trucks should turn quickly, grind smoothly, and feel comfortable straight out of the box. Rather than relying on complicated features or unnecessary gimmicks, the brand concentrates on functional geometry and the details that make a difference during actual skate sessions.

The 8.5-inch width makes this configuration particularly well suited to modern street decks with matching axle widths. Riders who enjoy technical flatground, ledge combinations, and curb skating will appreciate the quicker pop response of the lower setup, while those spending time in skateparks can benefit from the stability of its reduced ride height. Because the trucks sit lower than standard-height models, wheel size and riser selection should be considered when assembling a complete setup, particularly for riders using larger wheels or preferring looser trucks.

For skaters around the San Gabriel Valley, from the ledges and curbs of Monrovia and Arcadia to the skateparks and street spots surrounding Pasadena, South Pasadena, Glendora, and Claremont, the ST1 Hollow Low offers a practical option for riders looking to refine the feel of their setup. Whether you're skating technical street spots or spending an afternoon working through tricks at the park, the combination of responsive turning, lower ride height, and generous grind clearance makes these trucks particularly appealing.

With their 50.0mm low-profile geometry, hollow kingpins, silver aluminum hangers, matte black baseplates, white bushings, and 8.5-inch axle width, the Slappy ST1 Hollow Low delivers a distinctive combination of control, quick response, and grinding performance. Sold as a pair, these trucks include two matching units for a complete skateboard setup. They're built for skateboarders who want the advantages of a lower truck without giving up the turning response and grind clearance that define the Slappy name.
