If you've lost the little selector off the top of your Illumina, there's no need to fret! Here's the replacement. Included with all new shocks.
Please note that the shipping cost will be a significant part of the price of this part. That's the nature of small, inexpensive light parts unfortunately. The best way to avoid that is to package this part in a shipment with others.
Fits both front and rear Illumina for the NA and the fronts only for the NB.
