Direct-Fit Sealing Kit

The Fel-Pro BS40427 Rear Main Gasket Set provides the seals required to prevent oil leakage at the crankshaft rear main bearing. It is intended for technicians and vehicle owners performing engine reassembly or addressing rear main seal failure on compatible applications.

Straightforward Component Replacement

Installation follows standard rear main seal procedures using basic hand tools and a seal driver. The transparent material allows visual confirmation of seating. The primary risk is damaging the sealing lip during insertion or misaligning the split halves, which creates an immediate leak path.

Application-Specific Part Number

Correct fitment is determined solely by matching the BS40427 reference to the vehicle manufacturer’s specification for the engine being serviced. No universal sizing or cross-reference data is supplied, so verification against the service manual or parts catalogue is essential before purchase.
