Sb Ford Rear Main Seal 260-283-302-2 PIECE

The SB Ford Rear Main Seal 260-283-302 2-piece by FEL-PRO is an essential engine gasket for serious Ford enthusiasts and rebuilders working with small-block engines. This two-piece design addresses one of the most critical sealing points in any engine—the interface where the crankshaft exits the block at the rear. Whether you're performing a full engine overhaul, replacing a worn seal causing oil seepage, or rebuilding a classic 260, 283, or 302 cubic-inch small-block, this OEM-quality seal delivers the reliability that separates a professional restoration from a problematic rebuild.

FEL-PRO engineered this rear main seal with precision-molded elastomer material designed to withstand engine oil temperatures and pressure cycles without degradation or weeping. The two-piece construction allows installation without removing the crankshaft—a significant labor advantage in tight engine bays or complete teardowns. Each half seats firmly against the crankshaft journal and block saddle, creating a leak-proof barrier that maintains proper oil retention throughout the engine's operational life. The compact design (4.75 x 0.75 x 7.4 inches) fits cleanly into the rear main cap assembly, and the 0.11 lb weight reflects the minimal material waste typical of FEL-PRO's engineering standards for automotive seals.

Mechanics and engine builders favor this seal for 1962–1985 Ford small-block applications, particularly in hot rod, muscle car, and street performance builds where oil leaks compromise engine bay cleanliness and long-term durability. Installation requires proper alignment during final assembly and torque specifications per manufacturer guidelines—precision that pays dividends in eliminating the chronic rear main seal leaks common to high-mileage or heavily modified engines. For anyone rebuilding a 260, 283, or 302 small-block, this FEL-PRO seal represents the quality threshold expected in professional machine shop and enthusiast builds.
