MFactory Close Ratio 6th Gear Only Subaru BRZ ZC6 Toyota 86 ZN6 FA20 MF-TRS-01GT6

Achieve the ultimate in acceleration with the MFactory Close Ratio Gears. After installing our gears, you will experience a phenomenal increase in acceleration, although with a slightly lower top speed. These close ratio gears are ideal for racing and high-performance applications where quicker acceleration is prioritized over maximum speed.

Diamond Cut to Exacting Tolerances from Forged High-Nickel-Chromium-Molybdenum Steel
MFactory gears are diamond cut to the highest standards using premium-grade High-Nickel-Chromium-Molybdenum Steel. This steel alloy is known for its exceptional strength, toughness, and resistance to wear and fatigue. These qualities ensure long-lasting durability and reliability, even in high-stress racing environments. The precision cutting process results in a perfect fit and finish, providing hassle-free installation and minimal maintenance.

Perfect Fitment & Finish for Hassle-Free Installation & Maintenance
Every set of MFactory gears is designed for perfect fitment, reducing the time and effort needed for installation. The high level of precision also minimizes wear on other drivetrain components, ensuring smooth and consistent performance. Routine maintenance is simplified thanks to the quality and durability of the materials used.

Designed Using Leading-Edge Solidworks 3D CAD & Cosmos FEA Software
MFactory utilizes the latest in CAD Computer-Aided Design and FEA Finite Element Analysis technology to create gears with optimal design and efficiency. Solidworks 3D CAD ensures precise modeling, while Cosmos FEA software allows engineers to analyze stress points and optimize the strength and performance of each gear. This results in advanced gear geometry that reduces friction and minimizes parasitic drivetrain losses.

Advanced Gear Geometry for Reduced Parasitic Drivetrain Losses
The advanced gear geometry used in MFactory close ratio gear sets reduces unnecessary friction within the transmission, allowing more power to be transferred from the engine to the wheels. On average, transmissions built with MFactory components transfer 1-2% more power to the ground compared to competing brands. This power gain directly contributes to faster acceleration and better overall performance.

Dual-Cone Carbon-Composite Synchro Technology for Honda B-Series
MFactory introduces an industry first: Dual-Cone Carbon-Composite Synchro Technology for the Honda B-Series. This cutting-edge technology, adapted from Hondas K-Series, ensures faster and more precise shifting, particularly in 3rd and 4th gears, where high rpm shifting is critical. The carbon-composite synchros offer improved durability, reduced wear, and smoother gear engagement, making them perfect for performance driving and racing.
