SBF Thrust Plate & Bearing Kit

The SBF Thrust Plate & Bearing Kit is designed for small-block Ford enthusiasts who prioritize reliability and performance in their engine builds. This kit addresses a critical weak point in the SBF architecture by effectively controlling crankshaft end thrust, which is essential for preventing crankshaft walk during operation.

The thrust plate and bearing assembly work by precisely managing the axial movement of the crankshaft, utilizing hardened thrust surfaces and complementary bearing geometry. This design ensures even load distribution and maintains tight clearances across the RPM range, accounting for thermal expansion and oil film dynamics.

Ideal for street engine builds, competition setups, and rebuilds, this kit is compatible with various SBF displacements, including 250, 260, 289, 302, and 351W. Builders from street rod fabricators to serious racers rely on this kit to maintain engine performance and longevity.
