This is a larger 7/8" (0.875") diameter bore rear wheel cylinders for your TR250 and TR6.  TR250s through 1969 TR6s use a 0.75" bore RWC as standard, 1970-1976 TR6s use a 0.70" bore RWC as standard.  The bore diameter, in addition to the brake line fluid pressure, determines the effective force applied to the brake shoes.  The larger the bore diameter, the more force produced given equal line pressures before and after.

Exclusively manufactured for us, our bronze valve guides have more material on the inside diameter allowing for more freedom at arriving at the desired valve guide clearance with various valves.  Our standard bronze valve guide and Viton seal kit for GT6 TR250 and TR6 models allows up to 0.450" of valve lift.  If you require a set of guides that will allow for greater valve lift, choose our HP set, which will allow valve lifts to 0.500".
