1010 Connecting rod alignment tool

Checking the straightness of your connecting rods is a vital step in any bottom-end rebuild, and this JIMS alignment tool makes the process much simpler. Designed for engines with a 0.791-inch diameter wristpin, this 4.5-inch long tool allows you to verify the alignment of the wristpin and connecting rod without having to remove the rods from the crankcases. This saves significant time while ensuring your engine's geometry is perfect. It fits 1936 to 1999 Big Twin models, excluding Twin Cam engines. Using this tool helps prevent uneven piston wear and potential engine failure by catching alignment issues early in the assembly process.
