# Seismic - Low profile wedge riser [3°+7°] (set of 2)

**Seismic ANGLED TRUCK RISERS  
**Precision-Machined • Ultra-Low Profile • _Easy to Stack_**_!_  
**_Package of one (1) 3-degree Riser and one (1) 7-degree Riser._  

Packaged in pairs of one (1) 3-degree Riser and one (1) 7-degree Riser, _with an advanced feature set never before seen in combination…_  
• Thin ends reduced to 0.5mm-thickness for _**lowest-possible profile**_.  
• Mounting hole dimensions highly optimized for easy stacking. _**No more bent bolts from riser hole misalignment!**_\*  
_•_ _**Biomimetic “honeycomb” structure**_ maximizes support with minimal material.  
• CNC-machined from tough composite with _**superior 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. Usually called “wedging,” this 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. Usually called “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.

\* Maximum recommended stacking is three (3) 7-degree Risers under 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).
