ACL Ford Prod. 4 140 1989-97 Engine Crankshaft Main Bearing Set

You get a full set of crankshaft main bearings in this kit, which means one box handles the whole engine rebuild. These ACL bearings are made to fit your 1979 Ford Mustang, helping to keep the crankshaft spinning smoothly within the engine block. Proper bearing clearance is crucial for oil flow and to prevent premature engine wear.

This set is undersized by 0.075mm, meaning it's intended for crankshafts that have been machined down to match this specific size during an engine rebuild. ACL has been making engine bearings for a long time, and these are well-built components designed to handle the demands of your engine. They are a solid option when you're rebuilding your engine and need reliable parts to get it back on the road.
