Triumph Pre Unit rocker box rebuild kit 500 650
This kit is designed to service rocker boxes on all Pre Unit 500 engines, and all Pre Unit 650 iron head engines. This kit includes:
4 rocker box inspection caps ( 70-1577 or E1577 )
4 AFM rocker box gaskets ( 70-1650 or E1650 )
4 rocker oil feed copper washers (70-1335 or E1335 )
DO NOT USE ANY SEALANT ON AFM GASKETS
These gaskets were proudly manufactured in the USA, with materials from the USA by Cleveland Gasket® These are aluminum core with a nitrile rubber bonded to both sides. This AFM gasket material has excellent temperature resistance, torque retention, and compression. No sealant of any type is needed, and due to the high rate of recovery when disassembled, in most cases the gaskets can be reused. These gaskets have been tested both on the street and at the Bonneville Salt Flats, and have been proven to be superior to anything available in fit or function. There will be no pink, green, or blue gasket material hanging over the edge of your rocker box. There will be no drama or discussion about which sealant to use and how to apply it.
These pre unit rocker box gaskets replace Triumph part # 70-1650 or E1650, and are .032" thick.
This gasket set has been made with the highest quality materials and technology currently available.
