Gates Snubber Spacer Kit
The Gates Snubber Spacer Kit adapts all Gates snubbers for use with 142 mm installation widths and more. It consists of a screw and spacers, as shown in the photo.
Why choose this tool?
Adapts every snubber. Makes all snubbers usable with 142 mm installation widths and more.
Screw and spacers. A screw with spacer rings in one kit.
Keeps the belt on. A correctly spaced snubber keeps the belt on the sprocket.
For wider hubs. Made for rear ends with wider installation widths.
When do I need it?
Use the kit when your rear end has a wider installation width, 142 mm and more, and the snubber has to reach the belt. Check the snubber’s position: it should sit about 1 mm from the back of the belt and not touch it.
Which snubber part do I need?
The RDM Snubber is the snubber itself and comes with its screw. The Snubber Spacer Kit adapts snubbers to 142 mm installation widths and more; the Snubber Screw is a spare screw.

Frequently asked questions
Do I need the kit for every bike?
No, only if your rear end has an installation width of 142 mm or more and the snubber has to be adapted. Tell us your frame and hub and we will check.
Do I need special tools for a belt drive?
A belt drive needs far less than a chain, but the right tension and alignment matter. Gates offers tools for checking tension, checking alignment, fitting sprockets and protecting the belt – see the table above, and ask us which ones suit your bike.
Why does sprocket alignment matter?
Front and rear sprockets must stay aligned within ±1.0 mm. Misalignment can cause tooth jump, faster wear, noise, belt derailment or belt failure.
