ACL Mazda 4 G6 FE DOHC 1988-94 Engine Connecting Rod Bearing Set

When you're rebuilding or refreshing the engine in your 1995-2002 Kia Sportage, the connecting rod bearings are a critical component. These ACL 4B8140A-.25 bearings are designed to replace your stock ones, ensuring proper oil clearance and smooth operation between the connecting rod and crankshaft. This particular set is .25mm undersize, meaning it's intended for crankshafts that have been machined down to match this specification during an engine rebuild.

ACL has been making engine bearings for a long time, and they're known for their well-built components. These bearings are made with a multi-layer construction that includes a steel backing for strength, a bronze-aluminum alloy overlay for good wear characteristics, and a bearing overlay for the actual running surface. This design helps manage heat and provides a solid surface for the crankshaft to rotate against, all while maintaining the precise oil clearance needed for your engine to run correctly. They fit a range of Mazda engines as well, so if you're working on a B2000, B2600, or MPV from the late 70s to mid-90s, these could be what you need.

When installing these bearings, it's important to ensure your crankshaft journals are clean and within the specified .25mm undersize tolerance. Always refer to your vehicle's service manual for the correct installation procedure and torque specifications.
