If you find yourself missing shifts repeatedly, you may have worn dog rings. Trying to race with worn dog rings invites engine damage due to over-revving. These genuine Hewland dog rings fit the Hewland LD200 gearbox only. Sold individually.
We also offer Hewland Dog Rings for Mk-Series Gearboxes (Part No. 1410-A47H) for Mk 4 through Mk 9, Staffs, and original Formula Mazda (Webster 300) gearboxes. Although the two designs are dimensionally similar, they are not interchangeable.
