P2R Crank Washer Kit will extend the crank shaft enough to allow proper fitment of Flywheel for engines where the Crankshaft does not extend far enough. Kit includes Washer and 8 x OEM Honda long flywheel bolts.

This is needed  when installing a crankshaft from a 2009 and newer J series engine into an older generation J series block.  For example installing a J37A4 crankshaft into a J32A3 block.  

Note: 2009 and newer J series crankshaft's have the crank position trigger aka pulse plate bolted onto the end of the crankshaft. These crankshaft require machine work to fit into older gen blocks.
