Seismic Angled Truck Risers (Wedges) Precision-Machined • Ultra-Low Profile • Easy to Stack! The Seismic Angled Riser Pack Contains The Following: 1x 3° Riser 1x 7° Riser The risers are pre-drilled for Old School mounting hole pattern but accommodate the New School hole pattern too. Featuring: The Wedges feature super thin ends - reduced to just 0.5mm for the lowest possible profile, and minimum impact on truck height. The mounting hole dimensions are highly optimised for easy stacking. No more bent bolts from riser hole misalignment! The Biometric "honeycomb" structure maximises support, with minimal material. CNC machined from tough composite material with super dimensional stability. Highly resistant to deformation from extreme loads and impacts. How to use Angled Truck Risers (aka Wedges) For quicker steering response: Orient the thin end of the Wedge towards the end of the deck. This is referred to as “wedging,” which is most commonly done with the front truck. Just note that wedging decreases your leverage on the suspension parts (bushings or springs), so you might want to loosen them or even switch to softer ones. For slower steering response: Orient the thick end of the Wedge towards the end of the deck. This is referred to as “de-wedging,” this is most commonly done with the rear truck, especially on racing boards. Just note that de-wedging increases your leverage on the suspension parts (bushings or springs), so you might want to tighten them or even switch to stiffer ones. Wedging your trucks usually has a small effect on wheelbase length – generally not more than a small fraction of an inch. The exact change depends upon truck axle height; and angle, number, and orientation of the Wedges. *We recommend the maximum amount of stacked risers to be no more than 3 on a single truck. Always orient Risers with the tall end at a right angle to the Deck bottom – this keeps Riser holes aligned parallel to Deck and Baseplate holes. Seismic cannot guarantee against bolt bending caused by poor bolt quality, off-spec baseplate or deck holes, and/or improper fastening (too tight or too loose).
