This special spacer from Webster converts the 5-Speed 1st/Reverse Hub to a 4-Speed 1st/Reverse Hub in Hewland or Webster Mk8 or Mk9 gearboxes. It is not used in a 5-speed gearbox. With hub, replaces Hewland part number HC84-226.
If standard Mk 9 gears (1/2" thick) are used, this spacer can be installed on the standard 5-Speed 1st/Reverse Hub (Part No. 1410-A42-95, sold separately). We also offer a special 4-Speed 1st/Reverse Hub for Mk4 First Gear (Part No. 1410-A42-94, sold separately). This hub is designed specifically for use with the thicker (9/16") Mk 4 first gear.
