These flexible sleeves slip down over the CRC body posts and provide better support for your body.
They come approx. 21.5mm tall, and can be trimmed shorter if desired. Included with the mounts will be a set of shims (2 each - 1mm, 2mm, 4mm, 6mm, 8mm) to place under the mounts to fine tune the height for different bodies.
These sleeves are a press /tight fit on the lower portion of the CRC body post.
