Precision Sealing for Align-Bored SBC 400 Engines

When you have had your Small Block Chevy 400 block align-bored, standard seals may not provide the necessary clearance or compression. The FEL-PRO 2-piece rear main seal is specifically engineered to accommodate the unique tolerances of align-honed main journals. This ensures that your high-performance build remains leak-free under demanding conditions.

Why Choose FEL-PRO for Your SBC?

• Align-Bored Compatibility: Specifically designed to work with machined blocks where standard seals might fail.
• Advanced Synthetic Rubber: Resists oil degradation and maintains elasticity over thousands of miles.
• Easy Installation: The 2-piece design simplifies the assembly process, perfect for engine builders working with the engine in the chassis.
• Reliability: FEL-PRO is the gold standard for engine gaskets, providing peace of mind for your high-horsepower build.

A leaking rear main seal is more than just a nuisance; it can lead to oil contamination of your clutch or torque converter and create a mess under your vehicle. By selecting a seal designed for your specific machine work, you eliminate the guesswork. This seal provides the tight fitment required to keep your oil inside the pan where it belongs. Whether you are racing or cruising, ensure your engine's integrity with the right components. Find all your essential engine parts and performance gaskets at GGCRACING.
