Seismic 105mm Stable Turn 30°

Seismic® Aluminum Trucks: The Next Generation

The first of the new generation of carving-oriented trucks, and still the best! Seismic trucks deliver seriously advanced performance for longboarding, slalom & downhill, bowl & pool riding, all-purpose cruising, and cross-training for snowboarding, surfing, etc.

Four All-Metal Hanger Widths
105mm (6.8" axle)
130mm (7.8" axle)
155mm (8.8" axle)
180mm (9.8" axle)

• Both New School and Old School Mounting Holes
• Two Baseplate Geometries - Quick-Turn 45° and Stable-Turn 30°
• Both baseplates compatible with all hangers, springs and hardware.

WORLD'S MOST ADVANCED TECHNOLOGY AND CONSTRUCTION
• Progressive-rate dual spring system with tension adjustment and anti-buckling - for maneuverability with control, stability and power
• Rock-steady steering geometry - for totally predictable turning response
• Industry-leading body styling (including weight-saving cutouts in 105mm and 130mm hangers)
• Hybrid two-part baseplates (metal lower, composite upper)
• Low-friction bearing interface
• Bulletproof kingpin fastening
• Kingpin shoulder recessed inside baseplate for greater strength

TWO SPRING FAMILIES
Original high-rebound metal coil springs and new high-dampening urethane springs, both available in multiple color-coded strengths. Entire system re-engineered for larger range of spring compression/hanger articulation. High-rebound springs re-engineered with more progressive rate profiles. Adjustable tension, easily exchanged for softer or harder springs. Wrenches included.
New high-rebound spring strengths include Bone Max-Light, Bright Green Super-Light, Blue Extra-Heavy, and Black Super-Heavy.

AXLE HEIGHT
Originally designed with moderate (56mm) axle height to accommodate a variety of wheel sizes. The new 30-degree baseplate positions the axle slightly lower.

LIGHT WEIGHT
11 - 14 ounces each, depending on hanger width, baseplate geometry and spring type/strength.

VERSATILE AND COMPETITION-TESTED
With four widths, two geometries and multiple spring strengths in both high-rebound and high-dampening formulas, the new line of Seismic trucks offers more tuning options than any other truck product line in the history of the skateboard industry. This promises superior performance for longboarding, slalom, downhill, all-purpose cruising, Old School park/pool styling, and even street!

Unlike conventional brands, the inner face of Seismic trucks is a smooth, even plane. It can’t possibly hang up on curbs or the lips of ramps and bowls. The head of the pivot pin can’t be damaged by grinding or lap-overs (unless you wear all the way through the axle).

Seismic trucks are easy to adjust and maintain. All you need is the standard Allen wrenches (included) used to mount trucks and tighten king pins.
