Ford Performance 289-302 Small Block Oil Pan Reinforcement Rails 3/16" Steel M-6674-302

Oil pan leaks are a persistent problem on high-mileage Small Block Ford engines, often caused by flex and vibration at the pan flange. These reinforcement rails distribute clamping force evenly across the gasket surface, dramatically improving seal integrity without requiring pan removal or modification. If you're running a 289, 302, or stroker variant—especially in a performance application—these rails are essential insurance against costly oil loss and engine damage.

The 3/16-inch steel construction provides the rigidity needed to maintain a consistent gasket crush, eliminating the stress concentration points that lead to leaks. Installation is straightforward: simply position the left and right rails on the oil pan flange, use the recommended longer bolts for proper clamping depth, and pair them with Ford Performance's one-piece silicone gasket for optimal results. Suitable for street, strip, and road racing builds where reliability matters.
