Description

Using advanced Solidworks 3D CAD and Cosmos FEA software, the gear geometry is optimized to increase tooth strength and minimize parasitic drivetrain losses. Testing confirms that transmissions equipped with these gears transfer an average of 1-2% more power to the ground compared to competitor gearsets, making them a recommended upgrade for vehicles running 400hp or more. Constructed from imported Japanese forged steel, each gear undergoes cryogenic tempering and state-of-the-art wide peen cleaning for superior toughness. The proprietary Ti-Moly coating further enhances surface hardness and thermal resistance while lowering friction. The included Honda B-Series gear set features straight-cut ratios for 1st (2.786), 2nd (1.900), 3rd (1.430), and 4th (1.100) gears, providing a robust, off-the-shelf solution for sport compact performance.

MIA's Description

These gears are diamond-cut from forged high-nickel-chromium-molybdenum steel and finished with a proprietary Ti-Moly coating to reduce friction and improve thermal resistance.
