Based in Boulder, Colorado, Seismic Skate Systems is one of the oldest and most respected longboard brands in the world. They've been pushing the envelope of progressive carving technology since 1993, when they introduced the first high-precision truck of the modern longboard era. Seismic designs and manufactures high-performance trucks, wheels, bearings, decks and completes for carving, cruising, freeride, racing and beyond. Their mission is:
...to use the most advanced materials and engineering technologies to radically enhance the riding experience of everyone who wants to skate, however they choose to do it – all at an affordable price. We want to broaden the technical and stylistic potentials of all skateboarders, and to make skateboards accessible as tools of transportation and self-expression to the widest possible audience.
Power, stability, maneuverability, and control since 1993No truck has more energy return, more precision, or better steering control. The world’s best for pumping!
Stronger, lighter, and better-lookingOur crack team of engineers and industrial designers scoured every cubic millimeter of the previous (G4) model – looking for material to trim and spots to toughen, all while improving aesthetics.
More precise Spring SystemBreakthrough Spring Cap design keeps Springs much straighter as they compress – resulting in a larger turning range and enhanced steering control.
Easier maintenance and better Pivot Bolt fasteningThicker, stronger Pivot Bolt is easier to remove and install, and it threads more securely into a larger Baseplate Locknut. Stronger, reusable Pivot Bolt Clip is easy to remove and install by hand, and it’s fastened to a rubber “leash” that prevents it from ever getting lost. Ingenious new multi-part Baseplate structure creates uniform thickness at mounting corners, so you need mounting bolts of only one length.
Most components backwards compatible with older modelsException: G5 Pivot Bolts, Baseplate Locknuts, and Pivot Bolt Clips will not fit older (G4) baseplates; and older (G4) Pivot Bolts, Baseplate Locknuts, and Pivot Bolt Clips will not fit G5 Baseplates.
Hollow AxlesHollow axles reduce the overall truck weight and reduce leg fatigue on longer push distances.

Skateboard trucks are the metal T-shaped pieces that mount onto the underside of the skateboard deck. When selecting skateboard trucks, the width of your truck axle should closely match the width of your skateboard deck. The truck size can be measured by the width of the hanger or the width of the axle. Every skateboard requires two trucks.
There are several parts that make up the skateboard trucks. The axle is the pin that runs through the trucks to which the wheels will attach. The hanger, usually made of metal, is the largest part of the skateboard truck that is somewhat triangular in shape. The axle runs through the hanger. The kingpin is the large bolt that holds these parts together and fits inside the skateboard bushings.
When purchasing, you will receive the two trucks necessary to assemble your skateboard. Skateboard trucks come in various sizes and colors, and Warehouse Skateboards carries a huge selection of brands to fit your personal preference.
Truck profile is the distance between the bottom of the skate deck and the hanger. In general, a mid-sized truck works well for most skateboarders, but high or low trucks may be preferred for different styles of skating.
LOWProvides extra stability for flip tricks, designed for small wheels (50-53mm wheel size recommended)
MIDGood all-around profile for street or park (53-56mm wheel size recommended)
HIGHGreat for cruising and carving, designed for large wheels (56mm+ wheel size recommended)
