1999-2004 Ford Mustang Gear Kits

Revitalize your Mustang's transmission performance with comprehensive Gear Kits that deliver crisper shifts and improved durability under high-torque conditions. These 1999-2004 Ford Mustang Gear Kits address common weakness points in factory transmissions, providing stronger components and optimized gear ratios for both performance and longevity.

 

The real transformation happens when you upgrade to precision-cut gears with proper heat treatment and stronger synchronizer assemblies. Sure, the install isn't for the faint-hearted, but the resulting rifle-bolt action transforms the entire driving experience.

 

Complete your Mustang's drivetrain upgrade with 1999-2004 Ford Mustang Clutches for improved power transfer, 1999-2004 Ford Mustang Shifters for shorter throws, and 1999-2004 Ford Mustang Transmission Accessories for improved cooling and function.
