PPG 1–4 Synchro Mesh Gear Kit for Honda K-Series Transmissions
Upgrade the strength and consistency of your K-Series drivetrain with the PPG 1–4 Synchro Mesh Gear Kit. Designed for drivers who want a noticeable improvement in durability and gear engagement without jumping to a full dogbox setup, this kit delivers a smoother, stronger, and more confident shifting experience. Whether you're daily driving, road racing, or hitting weekend events, this upgraded gear set gives your Honda or Acura transmission the reliability and performance it deserves.
This PPG gear kit fits a wide range of K-Series platforms, including the 2002–2006 Acura RSX, 2004–2008 Acura TSX, 2002–2011 Honda Civic Si, 2003–2007 Honda Accord, 2002–2006 Honda CR-V, and 2003–2011 Honda Element. It replaces 1st through 4th gears with your choice of helical-cut or straight-cut designs, both using your factory-style synchro engagement for easy drivability. Helical gears offer quieter operation and a more OEM-like feel, while the straight-cut option reduces friction and frees up power—perfect for higher horsepower builds. You can also run your OEM final drive or upgrade to an optional PPG final drive for even better acceleration.
If you’re building a strong street car or a reliable track setup, this PPG K-Series gear kit is a smart investment. It’s engineered to handle the abuse that stock gears simply can’t—and it does it while still keeping the transmission easy to drive. Strong ratios, smoother shifts, and a design built around real performance make this gear set one of the best upgrades you can put inside your K-Series transmission.
