Clevite Ford Pass & Trk 330 352 359 360 361 389 390 391 427 428 Main Bearing Set

When you're rebuilding the bottom end of your Ford FE engine, the main bearings are critical for keeping everything spinning smoothly. This Clevite MS863P main bearing set uses a tri-metal construction, which is a popular choice for its ability to handle the loads and heat generated in these engines. This design helps to reduce friction and wear, ensuring a longer life for your crankshaft and block.

These bearings are designed to fit a wide range of Ford and Mercury vehicles from the mid-60s to the late-70s, including popular models like the Ford F-Series trucks, Fairlane, and Mercury Cougar. The tri-metal material offers a good balance of strength and conformability, allowing the bearing to adapt to minor imperfections in the crankshaft journal while still providing solid support. This makes them a solid option for both daily drivers and more performance-oriented builds where reliability is key.

Proper installation is key with any bearing set. Make sure your crankshaft journals are clean and within spec, and always follow the manufacturer's recommended torque procedures when installing the main caps. This set is designed as a direct replacement, so it should fit right into your existing engine block without modification.
