ACL Holden/Opel/Pont. 4 1.6/1.8/2.0/2.2 1982+ Race Series Main Bearings

Worn main bearings can cause excessive engine noise and oil pressure issues, especially in performance applications. These ACL Race Series Main Bearings are designed for engines needing a precise fit and reliable performance. They are built to handle the demands of modified engines, offering a solid option for rebuilding or upgrading your 1.6L, 1.8L, 2.0L, or 2.2L Holden, Opel, or Pontiac 4-cylinder engine.

ACL has been a well-known name in engine bearings for a long time. These Race Series bearings feature a specific material composition and design intended for engines that are pushed harder than stock. This particular set is 0.25mm undersize, which is important if your crankshaft journals have been machined down during a rebuild. Using the correct undersize bearing ensures proper oil clearance, which is critical for engine longevity and performance. They fit a wide range of engines from 1982 onward, including those found in the Daewoo Leganza, Nubira, and Suzuki Reno.

When rebuilding an engine, especially for performance, using quality bearings like these ACL units is key. Make sure to check your crankshaft journal measurements to confirm if the 0.25mm undersize is appropriate for your build. Proper installation and adherence to oil clearance specifications are essential for these bearings to perform as intended.
