    Gear Sets with Consistent Performance Output

    US Gear Lightning Series Ring and Pinion Gears are an improvement over their high-quality standard aftermarket ring and pinion sets. Lightning Series Sets feature an Isotropic Super Finish that eliminates the break-in period with a new ring and pinion set; while providing superior wear and corrosion resistance. This Isotropic finish also provides smooth operation by reducing vibration and noise, along with lowering lubrication requirements and costs. Lightning Series ring and pinions deliver unparalleled performance in the most difficult conditions and are available in a variety of sizes and styles with the muscle to tame large amounts of torque at the starting line.
