Kent-Moore (later SPX / Bosch Automotive Service Solutions) produced these J-series tools as OEM-recommended special service tools for GM/Detroit Diesel dealerships.
These are professional diesel shop tools, typically sold through specialty automotive/diesel tool distributors rather than general retailers. Individual components like the body and handle appear on sites such as Tillman Tools and Auto Tool World. Availability of complete kits or used examples varies; search eBay or diesel tool specialists for “J-33421” or “Kent-Moore cam follower tool V-71.”
An earlier similar tool for Series 53 engines is J-5840. Always follow the official Detroit Diesel service manual procedures and torque specs when using the fixture.
