These spacers are designed to reduce the distance or gap between the rails of the Wheeldock chock; therefore, one chock can now be made to fit several narrower tires. Our spacers are sold in kits or by individual thicknesses. Kits go up to the total thicknesses indicated in the list below and will create any thickness needed in 1/8-inch increments.

First, determine how much total gap you have to fill. You can find this dimension by rolling your bike into the chock and measuring the gap. This will take two people, and you will need to hold the bike straight up for accurate measurement. You can also measure the overall width with a C-clamp, which just touches the sidewalls at the widest point and measured with a scale. We also list the different widths needed on our sizing chart. See Chart Below.

When fitting a narrower tire into a wider chock, you will need spacers measuring the thickness found where the two sizes intersect above.

Example: You have an Ultra H-D that takes the model #5 and you occasionally haul a sport bike (all sport bikes take model #3). The spacer thickness needed is ¾ inch. Kit A will work, or you can just purchase one each of a ½-inch and a ¼-inch spacer.

We ship our spacers with 2 reusable, high-strength (250 Lb.), nylon zip ties. We recommend always using these ties over lighter ones. Extra ties can be purchased from the Wheeldock Co.

Always use a front safety strap and two side straps for transporting your motorcycle. See the full instructions for strap placement in the owner’s manual, which comes with the Wheeldock chock.
