DSS-A2 | Arctic Spider Shim 2010-12

Using different thickness and diameter shim washers under the spider is something racers sometimes use for belt grip and engagement characteristics.

Some of the 2010-2012 Arctic drive Clutches have a new cast spider that is a bit different geometry and only have one .060 steel shim under the spider from the factory because the spider is different. By replacing that single steel washer with this steel stepped shim would allow .085 thickness of that large diameter shim (instead of the stock .060, thus untucking weights more) and also .025 more belt side clearance. The racers that like to Experiment with more belt grip may prefer this one piece shim to stacking washers of different diameters.
