Slappy ST1 Inverted Hollow Lights Ultra Low Kingpin Skateboard Trucks | 8.25"
The gold standard for grind clearance.
Slappy Trucks is the brainchild of Mike Sinclair — two years of obsessive refinement in pursuit of the perfect truck. The ST1 Inverted Hollow Lights takes everything great about the ST1 and pushes it further. The ultra low inverted hollow kingpin sits deeply recessed with a shorter top bushing, creating even more grind clearance and an increased Slappy angle — meaning smoother lock-ins, zero kingpin drag on Smith grinds and feebles, and a noticeably quicker, snappier turn. No break-in time. No hang-ups. Guaranteed.

About Slappy
Slappy Trucks started the way the best things in skateboarding do — someone obsessing over a problem until they solved it. During the pandemic, pro skater Mike Sinclair spent over two years working through endless versions of hangers, baseplates, bushings, kingpins and turning radius, chasing a truck with maximum grind clearance that didn't sacrifice the turn. Strong, light, classic in feel — and built from scratch. As Sinclair puts it, just trying to create something new with Slappy Trucks.
