SBF Thrust Plate & Bearing Kit

The COMP CAMS SBF Thrust Plate & Bearing Kit (Part No. 3135TB) is a precision camshaft thrust bearing assembly designed for Small Block Ford engines. This roller-style bearing kit provides critical support for the camshaft, controlling endplay and preventing unwanted axial movement that can compromise valve timing and engine durability. The 0.142-inch thickness specification is engineered to match Small Block Ford block specifications and factory tolerance stack-ups.

The roller bearing design reduces friction compared to traditional flat thrust plates, which translates to lower parasitic drag during engine operation. Steel construction with natural finish ensures corrosion resistance and longevity in both street and performance applications. Proper camshaft thrust bearing installation is essential in any SBF rebuild—inadequate endplay control can lead to valve timing drift, reduced efficiency, and potential camshaft or bearing damage over time. This kit addresses a core maintenance requirement that many engine builders prioritize during restoration or performance upgrades.

SBF enthusiasts performing engine overhauls, hot rod builds, or stock replacements depend on this bearing kit to establish proper camshaft support. Whether restoring a classic Ford engine or assembling a modified small block, correct thrust bearing specification and installation ensures reliable valve train geometry and long-term durability. COMP CAMS' focus on precision valvetrain components makes this kit a preferred choice among builders who prioritize proper engine mechanics over shortcuts.

This thrust plate kit fits within the broad ecosystem of Small Block Ford engine components, where bearing clearances and endplay control are fundamental to reliability. Selecting OEM-spec or equivalent-grade components like this COMP CAMS kit reduces the risk of field failures and ensures the engine performs as originally designed or improved upon by the builder.
