Product Details

When you're rebuilding the bottom end of your 1999-2005 Subaru Impreza, you'll get a set of Clevite main bearings. These bearings are crucial for supporting the crankshaft and ensuring it spins smoothly within the engine block. This specific set is designed for the 2.5L QR25DE engine, which is common in many Subarus from the early 2000s.

Clevite is known for making well-built engine components, and these main bearings are no exception. They are manufactured to meet the specific tolerances required for the QR25DE engine, helping to maintain proper oil clearance between the crankshaft and the block. This is important for oil pressure and overall engine health. The MS2258H026MM part number indicates these are 0.026mm undersize bearings, which are used when the crankshaft journals have been machined down to correct for wear or damage.

If you're machining your crankshaft during an engine rebuild, make sure to order the correct bearing size to match the journal dimensions. These Clevite bearings are a solid option for getting your engine back in reliable running condition.
