ACL 91-02 Saturn 4cyl .25 Oversized Rod Bearing Set

Doing an engine rebuild on your Saturn SL2, likely with the DOHC 1.9L engine? These ACL rod bearings are a solid choice for getting your engine back in shape. They're designed to replace the original bearings, but with a slight adjustment: they're 0.25mm undersize. This means they're intended for crankshafts that have been machined down by 0.25mm to correct wear or runout.

ACL has been making engine bearings for a long time, and these are well-built for the job. They use a tri-metal construction, which is pretty standard for performance and rebuild applications. This design helps them handle the loads and heat generated in the engine while maintaining good oil film. Because they're a direct replacement part, they fit right into the connecting rods and crankshaft journals, assuming the crank has been properly prepared to the correct undersize.

When you're putting these in, make sure your crankshaft journals are clean and have been machined to the specified 0.25mm undersize. It's also a good idea to check your oil clearances with Plastigage to confirm they're within spec before buttoning everything up. These bearings are sold as a set, enough for all the connecting rods on your 4-cylinder engine.
