The folks at HQ developed a unique spring-loaded truck which results in tight turns with stability, power and total control. With this truck system no more sloppy trucks, blown or cheap skateboard bushings so sluggish axle rebound is now a thing of the past!

Spring progressive rates are calculated with Mathematica® software, using the world’s most advanced scientific model of skateboard carving dynamics. The result: Your turns get tighter at a velvety smooth, even rate as you weight the edge of the deck, so it’s incredibly easy to feel how far to lean to make turns of varying sizes. No twitchiness, no dead spots, just totally fluid response and a revolutionary combination of stability and maneuverability.

To accommodate varying body sizes and skating styles, springs come in eight strenghts that are easily exchanged using included wrenches. Adding tension to the springs creates even more customized response. Unlike grommets, the springs don’t need to break in, they’re not temperature sensitive, and they’ll virtually never wear out!

Some skaters can’t believe at first that any truck can make sharp turns while feeling so smooth and stable. If you’re used to floppy or squirrelly turning, trucks may feel a bit tight at first, especially if you don’t thrust through your turns. But it won’t take you long to adjust to the superior handling and fall in love with the superior power!

Note: Springs do not absorb vertical shocks; they simply do what grommets are supposed to do, only far better.

Seismic Breakthrough Technology and Construction

Every other skateboard or longboard trucks on the market is based on 1930s roller-skate technology, or on recycled 1970s skateboard designs – “reverse kingpin” trucks like the 1977 Gullwing H.P.G. IV (the first of its type) and the 1978 Veriflex connection; or else “torsion” trucks like the 1976 Pittsburg (the first of its type) and the 1977 Magnum (developed by the Mattel Toy Corp).

Founder Dan Gesmer (a freestyle innovator and Yale graduate profiled in the 1988 Powell-Peralta video Public Domain) wasn’t satisfied with old technology hampered by sloppy geometry, poor steering control and sluggish axle rebound. He spent ten years analyzing skateboard carving dynamics and developing the complex mathematical model used to calculate the power rates for the custom-made springs.

Skate Trucks are for turning. Skater-designed and skater-engineered, 100% grommet-free simply they do it better.

  • Progressive-rate dual spring system integrated with rock-steady steering geometry – for sharp, predictable turning with advanced control and stability.
  • High-rebound metal coil springs with anti-buckling and tension adjustment systems – for smooth, customizable response and unparalleled power out of turns.
  • Hybrid two-part baseplates (metal lower, composite upper) in two geomitries, drilled for both New School and Old School mounting patterns.
  • Quick-Turn 45° and Stable-Turn 30° baseplates interchangeable with all hangers, springs and hardware.
  • Industry-leading body styling.
  • Smooth plane of inner face immune to hang-ups, and recessed kingpin head protected from grinds.
  • Low-friction bearing interface and bulletproof kingpin fastening.
  • Kingpin shoulder recessed inside baseplate for greater strength.
  • Original model patented in 1993 (U.S. #5,263,725), predating cheap imitations in the off-road board market. International patents pending.
