Rear Main Seal 2-Piece Viton for Small Block Ford SBF 351W C5689 New

The Rear Main Seal 2-Piece Viton is an essential sealing component specifically designed for Small Block Ford engines, particularly the 351W variant. This high-performance gasket is engineered to fit tightly around the crankshaft, ensuring a reliable seal that keeps engine oil from leaking. Made from premium Viton material, known for its superior resistance to oil and high temperatures, this rear main seal is crucial for maintaining engine integrity and performance. This seal not only provides excellent durability but also minimizes the risk of oil leaks that could lead to engine damage or increased maintenance costs.

When it comes to installation, the 2-piece design offers significant advantages over traditional single-piece seals. It allows for easier installation and adjustment, providing a more precise fit. This design decreases the likelihood of installation errors, ensuring optimal sealing efficiency. By using a 2-piece configuration, mechanics can easily replace the seal without removing the entire rear main bearing cap, significantly reducing labor time and complexity during engine rebuilds or repairs.

The use of Viton rubber enhances the longevity and reliability of the seal, as it withstands extreme temperatures and resists wear and tear over time. This means that you can expect the Rear Main Seal to perform effectively under demanding conditions, maintaining a secure barrier against leaks and protecting vital engine components.
