Cusco 20-23 Toyota Gr Yaris Close Ratio Gear Set (1st/3rd/Reverse Gears & Input Shaft)

If you're looking to get more out of your Toyota GR Yaris on the track or in spirited driving situations, a close-ratio gear set can make a notable difference. This specific set from Cusco replaces your factory 1st, 3rd, and Reverse gears, along with the input shaft, to bring the gear ratios closer together. What this means for you is less of a drop in RPMs between shifts, allowing the engine to stay in its power band more effectively. You'll notice improved acceleration out of corners and a more responsive feel when you're pushing the car.

Cusco is well-known for its performance drivetrain components, and this gear set is built to handle the demands of aggressive driving. The gears are precision-machined for a solid fit and smooth engagement, which is crucial for durability and performance in a manual transmission. Replacing the input shaft ensures proper alignment and strength for the new gear set. This isn't a modification for everyday commuting; it's for drivers who want to optimize their GR Yaris for performance driving scenarios where every bit of acceleration counts.

Installing a gear set like this is a significant internal transmission job. It requires careful disassembly and reassembly of the gearbox. If you're not experienced with internal transmission work, it's highly recommended to have a professional mechanic perform the installation to ensure everything is set up correctly. This modification is designed to work with your existing transmission housing, but it's a comprehensive internal upgrade that changes the way the car accelerates through the gears.
