Top of the line slotted mushroom tappet / valve adjusters for all Triumph Bonneville, Tiger, Trophy, Tr6, Tr6c, T120, T120r, T120tt, T140, T140v, Tr7, 650 750 models with 5/16″ x 26 T.P.I. CEI thread. Our adjusters are manufactured from high carbon steel then hardened to Rockwell 58-60. They are identical to factory length and thread specs and will add years to the life of your valve train by smoothly pushing the stem down the guide because of the radiused head, instead of jamming it sideways like the original design. We also stock them for Norton 650, 750, 850 Twins as well as late 750 5/16 x 24 T.P.I. threaded Twins.
