ProAm's double boot kits features a pinch design that keeps the small inner boot firmly sealed under harsh conditions. It does this by using two flanges that bolt together pinching the inner boot in place. The kit's outer flange features a lip for a large outer boot. The outer boot is not included in the kit to allow your choice of leather or rubber boot.

These kits are designed to be used with ProAm or Fortin Mid Board hubs with 934 CVs. Individual flanges and boots for these kits are available separately.
