Aluminum Ultra Washers (8-pack) are an excellent upgrade to the stock steel washers that come with many 165 and UFS mount skates.  These are especially recommended for those that are seeking the absolute lightest setup possible or for frames that require a little extra wheel clearance.  

We always recommend the use of washers with frame mounting bolts to achieve the best performing mechanical joint.  Bolted joints missing washers will not distribute loads as well and may cause unnecessary flex in the joint.  Unfortunately, some skates do not have washers under the head of the frame bolts, often because there is insufficient clearance to the 2nd wheel.  The Ultra Washers are thinner than standard washers and will give you the necessary clearance.  

These washers should be compatible with most non-Endless frames, but please measure your frame before ordering.
