Product Description
Genuine Honda main crankshaft bearings (Upper Block) facilitate the rotation of the crankshaft within the cylinder block with minimal friction and wear. These precision components are manufactured to specific tolerances and are colour-coded to allow builders to achieve the exact oil clearance required for high-performance operation. Each bearing is supplied as a single half to allow for specialised sizing across the five main journal locations.

Important Sizing Information
Honda con rod and main bearings are colour-coded to indicate size. Genuine bearings are sold in halves, so you need to order two halves per con rod (8 total for all 4 rods) and two halves per crank location (10 total for all 5 locations). Select the correct size and colour based on journal clearances. Compatible with K-Series Engines K20A and K20Z. Priced per individual half.
