MFACTORY FINAL DRIVE GEAR 3.080 BMW 135I E8X 335I & 335D E9X

Achieve the ultimate in acceleration with the MFactory Final Drive Gears. Changing your final drive ratio can significantly alter the performance of your vehicle, allowing you to experience a dramatic increase in acceleration. By shortening the final gear ratios, MFactory gears provide an average 10-15% increase in torque throughout the entire rev-range compared to OEM final drives. This means quicker acceleration and improved responsiveness, making these gears ideal for both street performance and racing applications.

Diamond Cut to Exacting Tolerances from Forged High-Nickel-Chromium-Molybdenum Steel
MFactory final drive gears are manufactured from forged High-Nickel-Chromium-Molybdenum Steel, a premium alloy known for its incredible strength, durability, and resistance to wear. The diamond-cut process ensures each gear is machined with utmost precision, creating a flawless fit and finish. This leads to improved durability under high-stress conditions, such as during high-performance driving or track use. The high level of accuracy in the cutting process also guarantees smoother operation and less wear on surrounding drivetrain components.

Perfect Fitment & Finish for Hassle-Free Installation & Maintenance
With MFactory's commitment to precision engineering, each final drive gear is designed for perfect fitment and ease of installation. This ensures a seamless replacement process for the user, minimizing installation time and reducing the need for adjustments. The high-quality finish also helps reduce wear and tear on the gears, allowing for longer maintenance intervals and better overall longevity.

Designed Using Leading-Edge Solidworks 3D CAD & Cosmos FEA Software
MFactory employs the latest Solidworks 3D CAD software for accurate modeling, ensuring that every gear is designed with the highest precision. Cosmos FEA Finite Element Analysis software is used to simulate the stress points on the gears under various conditions, allowing for optimization of strength and performance. This design process leads to superior gear geometry that improves efficiency and minimizes stress points, ensuring a stronger, more reliable final drive.

Advanced Gear Geometry Minimizes Parasitic Drivetrain Losses
The advanced gear geometry used in MFactory final drive gears is designed to minimize parasitic drivetrain losses, which occur when power is lost due to friction within the transmission. By reducing these losses, MFactory gears transfer, on average, 1-2% more power to the wheels than competitor products. This increase in power transfer directly translates into better acceleration and improved vehicle performance, especially in competitive racing environments.
