Replace your transmission's weak link. These MTM straight-cut 3rd and 4th gears are a direct-fit strength upgrade engineered to handle serious power where the factory helical gears give up.

• Straight-cut design — spur-cut teeth carry load with no side thrust, making them far stronger and more consistent under high torque than the factory helical gears.
• Harder alloy — machined from a harder metal than the OE gears for greater durability and resistance to wear and breakage.
• 3rd gear — 1.70 ratio
• 4th gear — 1.25 ratio
• Uses factory synchros — designed to run your OEM synchronizers, so engagement stays clean.
• Synchronizers not included — works well with Synchrotech.

Good to know: Straight-cut gears produce a mild distinct whine that rises with speed — that's normal, and it's the sound of a stronger gearset. Transmission disassembly is required; professional installation recommended.
