    When your ATV, UTV, or motorcycle is due for a rebuild, trust Pro X Connecting Rods for the strength and precision your engine needs to run its best.

    Manufactured in Japan by industry leading OEM factories, the connecting rods in these kits are double forged, shot peened, and barreled to give you maximum consistency throughout the material and greatly increase the lifespan of the connecting rod. Pro X also designs precisely placed oil cutouts in their con rods to improve oil delivery to the lower crank and bearings, so all mating surfaces stay lubricated even during the most extreme operating circumstances. With this kit you’ll be good to go with a crankpin, big-end bearing, small-end bearing, and both washers.

    With Pro X’s exceedingly high-quality manufacturing techniques, count on these Connecting Rod Kits to outlast and outperform the competition for performance you can count on.

    Specs:
  • Double forged, shot peened, and barreled construction
  • Kit comes complete with crankpin, big-end bearing, small-end bearing, and washers
  • Drop in OEM fitment and installation
  • Precisely located oiling slots
