Trucks

Coming early 2013… the G5: an all-new, dramatically improved version of our original spring truck. In development for over four years, in collaboration with numerous engineers and industrial designers. Stronger, lighter, and better-looking, with easier maintenance and a more precise spring system.

At Seismic, we're not willing to cut corners or compromise quality/performance in any way. We sincerely appreciate your patience as we put the finishing touches on this advanced new version of the truck technology we first introduced in 1993. The final tweak was a subtle but critical adjustment to the design of the composite spring caps, which required a surprising amount of time and testing.

Compared to the previous version of our spring truck, the new model is stronger, lighter, and better-looking.  The spring system is more precise, and maintenance is easier.  Most components will be backwards-compatible with the older model. (Exception: the G5 pivot bolts, nuts, and clips will not fit the older baseplates; and the older pivot bolts, nuts, and clips will not fit the G5 baseplates.)

Creating and evolving the Seismic spring truck technology has truly been a decades-long labor of love.  It began in 1983 and continues to this day.  Our sincerest thanks to you for embracing the fruits of these efforts.

Power, stability, maneuverability and control right out of the box. Four widths, two geometries and eight spring strengths give unprecedented tuning options for the discerning longboarder, racer, cruiser and pool/park stylist. Often imitated, never equaled. More bang for the buck than any other truck available, and arguably the most highly-engineered product in the history of skateboarding.

For most boards, using a 30-degree truck at the tail and a 45-degree truck at the nose optimizes power, control, traction and stability. Exceptions: downhill speedboards (use 30-degree trucks and stiffer springs on both ends); twin-tip freeride setups (use 45-degree trucks on both ends); and recreational carvers (use 45-degree trucks on both ends).

For our best truck setup sugestions, just email us with anwers to the following questions:

• What is the length and width of your deck?
   Use wider trucks for wider decks.  Axle length should be about the same as deck width, or slightly less.

• Is your deck symmetrical, or does it have a real nose and tail?
   We usually suggest a 30-degree truck at the tail and a 45-degree truck at the nose, with stiffer springs at the tail than at the nose.  Use two 45-degree trucks on symmetrical "twin tip" freeride decks.

• Does your deck have a kick tail and/or a kick nose?
   We strongly suggest a 30-degree rear truck on non-symmetrical decks that have a kick tail.

• What is your height and weight?
   Use stiffer springs if you are heavy and/or tall.  Click here to see tables of suggested spring strengths by weight and style.

• What kind of skating do you like to do?
   We usually suggest a 30-degree truck at the tail and a 45-degree truck at the nose.  Use two 30-degree trucks and stiffer springs for dedicated high-speed downhill setups.  Use two 45-degree trucks on symmetrical freeride setups.

• How do you like to adjust your trucks - loose, medium, or stiff?
   Use softer springs for a loose ride, harder springs for a stiff ride.  

• Is your deck flexy or stiff?
   Use softer springs if your deck is very flexy.
