The DuoStand Ends let you upgrade your DuoStand Gen 1 to make it even more useful. The Ends feature grippy rubber caps that widen the DuoStand's base of support and add friction, both of which boost stability. They're also height-adjustable, so you can switch out your tires but keep your stand (for example, when installing winter tires). If your DuoStand already came with a pair of DuoStand Ends, they're available as replacement parts when yours are lost or worn. Use the DuoStand Ends to upgrade your DuoStand Gen 1. See your dealer for installation help. See this article for more information. Rubber-capped feet boost stability and prevent floor scratches when parking indoors Make the DuoStand height-adjustable to fit winter tires for year-round use Replaceable when lost or worn Compatible with all versions of DuoStand For the heaviest loads, add the Lockstand Extensions for maximum stability
