Pfitzner Performance Gearbox (PPG) is proud to announce a breakthrough in transmission technology—the straight cut dog set designed for the Toyota GR Corolla and Toyota GR Yaris. Engineered in partnership with our esteemed Japanese Master Distributor, Luck Co., who boasts extensive rally experience with Toyota, this product is a testament to PPG's commitment to cutting-edge performance and reliability under the most demanding conditions.

Crafted with rigorous precision, this dog set features an H-pattern shift, providing the tactile feedback and speed required for competitive racing. Unprecedented early access to the Yaris GR4 model allowed PPG engineers to tailor the gearbox specifically to the vehicle’s specifications before its public release. This proactive approach ensured that every nuance of the gearbox's design was optimized, guaranteeing that drivers receive a product not only fine-tuned for motorsport, but also robust enough to withstand high horsepower.

Pfitzner Performance Gearbox was one of the first to manufacture this heavy duty helical synchro gearset for the new Nissan R35 GTR. With massive worldwide popularity this direct replacement gearset has proved to be a winner in every application it has been used .

From Drag Strip to Hill Climb to World Time Attack it has achieved great results with consistence reliability from a product that is designed and produced in-house at our Australian Factory.

The R35 GTR gearset requires no computer re-programming and comes with factory gear ratio's, Motorsport grade steels are used in the wider gear profiles that are designed for strength , durability and quite operations. Pfitzner also treat every component to a unique heat treatment process and surface finishing processes that give the PPG product its unique appearance.

This set is designed for street and circuit applications and sets the benchmark in terms of quiet noise operation for everyday driving.

Pfitzner Performance Gearboxes has designed a heavy duty optimised close ratio synchro upgrade system based around the ever popular Tremec Magnum. This will also work in other T56 and TR6060 gearboxes such as Ford Falcon, Holden Commodre, Dodge Viper and many others.

The Mitsubishi Evo 4-9 Helical Cut Synchro Set is the perfect upgrade for anyone who wants a stronger gearbox without the excessive noise of straight cut gears or dog engagement. This heavy-duty synchro set is designed to suit the Evo 4-9 5-speed gearbox, providing optimized gear ratios and upgrading 4th gear to run the same double synchro as 3rd. Tested and proven for durability, this synchro set is a must-have for any enthusiast looking to enhance the performance and reliability of their Mitsubishi Evo. Experience smoother and more precise gear changes with the Mitsubishi Evo 4-9 Helical Cut Synchro Set!

Features Include:

• Input shaft with spigot - will be supplied with matching bronze bush for more support
• 4th gear upgraded to double synchro - comes with new 3rd/4th selector hub to accomodate
• Optimised Gear Ratios to minimise drop in rpm to keep car on boost
• Helical cut gear to minimise road noise
• Billet Selector Forks Optional
• Billet Selector Rails Optional

With a speed of operation usually only found in F1-type applications, Pfitzner Performance Gearboxes sequential systems integrate with modern 32-bit ECUs to provide closed loop strategies that are capable of providing sub-70ms gear shifts. This impressive speed of operation gives the PPG system a unique advantage over its competitors, optimizing the shift phase to allow the return of power through the transmission as soon as the dog is pre-engaged. This state-of-the-art measuring device allows PPG’s Tremec sequential gear system to map and track absolute position of the dog-rings to provide levels of barrel and selector position accuracy that were previously unobtainable. It also supplies next-gear stable calibration tables with precise and repeatable data. The PPG system circumvents a requirement for 100% ignition cuts when the gear change is made, meaning that many of the forces that unsettle a chassis during a gear-change operation are eliminated.
