Rear Main Seal Set

The Fel-Pro BS40656 is a rear main seal set designed for engine repair and maintenance. It provides the sealing components required to prevent oil leaks at the crankshaft rear main bearing area. This kit is intended for professional mechanics and experienced DIYers performing engine rebuilds or seal replacement jobs.

Transparent Seal Components

The set includes transparent-coloured sealing elements manufactured by Fel-Pro. The width specification is listed as not applicable, indicating the kit contains shaped seals rather than flat stock material. Verifying the exact engine application against the manufacturer catalog is the critical step before purchase.

Suited for Targeted Seal Replacement

This product suits technicians addressing a specific rear main seal failure on a compatible engine. It is not for buyers needing a full engine overhaul gasket set or those working on transmissions, timing covers, or other sealing surfaces. Shoppers without the exact engine model reference should consult a parts specialist first.
