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.
General setup suggestionsFor optimal traction, power, and control, we usually suggest a 45-degree truck at the nose and a 30-degree truck at the tail, with stiffer bushings at the tail than at the nose. Use two 45-degree trucks on symmetrical (twin-tip) freeride decks. Use stiffer bushings if you’re heavier and/or taller than average, softer bushings if you’re lighter and/or less tall.
Stabilized Geometry with no added partsAeon bushings pair to form a cylindrical hollow that locks around barrel-shaped hanger elements – a true bearing with no added parts. This patented design forces the hanger to rotate inside the tubular channel in perfect alignment with the pivot axis. Eliminates slop, aligns and stabilizes geometry without the downsides of support pins, spherical bearing inserts, or hanger plugs. Quick response from center and noticeably smoother, cleaner turns – even at deep lean angles that destabilize the steering of ordinary RKP trucks.
Advanced ControlBeyond barrel vs. cone: Aeon bushings have a wide hexagonal shape and tapering sides, for a smooth, intuitive resistance profile through a larger steering range. Tall but not too tall, for deep turns with no dive. Self-lubricating formula to prevent squeaking.
Lightweight & AffordableOptional hollow axles, elegant body sculpting, and the first-ever hollow pivot channel (extending into bearing section). Precision engineering is what counts, and the Aeon packs it in a moderately-priced cast design. (CNC body parts add high cost with no guarantee of high performance.)
Precision FitCustom contouring creates mechanical lock between boardside bushing and baseplate – no washer needed. Faced hangers for perfect interface with inside bearings. Top of baseplate sloped for flush contact with deck concave when dropthrough-mounted. (Nut seats kept flat.)
Hollow AxlesHollow axles reduce the overall weight of the truck by 0.64 ounces, allowing for reduced leg fatigue on longer pushes.

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)
