Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your Ford Ranger is one of their staples. When you're rebuilding or repairing your 4.0L V6 engine, these main bearings are critical. They sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation by reducing friction. If your engine is making knocking noises or showing signs of excessive wear, replacing these bearings is a key step in restoring its performance and longevity.

This set is built to meet the demands of the 4.0L V6 engine found in many Ford and Mercury vehicles. The bearings are made with a specific material composition designed for durability and consistent performance under engine operating conditions. They are manufactured to precise tolerances, which is important for proper oil clearance and to prevent premature wear on both the bearings and the crankshaft journals. This ensures that your engine runs smoothly and reliably after the rebuild.

When you're diving into an engine rebuild, having the right parts is crucial. This ACL main bearing set is designed as a direct fit for the specified Ford Ranger, Explorer, Explorer Sport Trac, and Mercury Mountaineer models with the 4.0L V6 engine. Make sure to follow the manufacturer's installation instructions carefully, paying close attention to oil clearances and proper torque specifications to get the best results from these well-built bearings.
