Piston Liner Heavy Duty 89mm

This is a extra strength Piston Liner to be used in with an 89mm Piston. Because of the limitations of the area on the block on a Triumph TR3 to TR4A, the liner has been strengthened in the middle with extra material to handle the extra pressure placed on the engine. These are NOT the standard liner which has been bored out to 89mm. The standard liner would not be capable of handling the pressures. Call for further details. Cross Reference CL3260A
