BBF Thrust Plate & Bearings

The COMP CAMS BBF Thrust Plate & Bearings delivers precise camshaft thrust control for Ford big-block applications, specifically the 351 Cleveland and 429-460 engine families. This moly-coated roller thrust bearing addresses one of the most common wear points in high-performance Ford builds by setting proper cam thrust clearance from initial installation. For builders working on restoration projects or performance upgrades, this component prevents the metal-on-metal contact that degrades timing gear accuracy over extended operation. The 3-piece design accommodates the specific geometry of Ford big-block timing systems.

At 0.142 inches thick, this thrust bearing plate provides the exact spacing needed to establish correct endplay without requiring custom machining or shimming. The steel construction with moly coating reduces friction at the bearing surface while resisting the heat cycling common in performance applications. COMP CAMS engineered this assembly to eliminate gear-to-block wear, a failure point that can introduce timing inconsistencies and accelerated component degradation. The roller bearing design minimizes rotational resistance compared to flat thrust surfaces, which becomes particularly relevant in engines seeing sustained high-speed operation. This component integrates with stock and aftermarket timing sets without modification.

Ford 429 and 460 owners building for street performance, bracket racing, or marine duty will find this thrust plate solves a known weakness in the factory timing system design. The assembly installs during any timing set replacement and requires no special tools beyond standard timing cover service procedures. We stock this alongside related parts and accessories for complete Ford big-block builds. Pair with quality timing components to maximize the longevity benefits this precision-fitted thrust bearing provides.
