Pfitzner’s scientifically mapped-out and technically sound design, coupled with its industry leading manufacturing and heat treatment processes, not only makes its gearbox components individually strong, but collectively robust too. The upshot of this combined strength gives each gear set an inherent durability. This leads to low wear rates and consequently, reliability and longevity.
These qualities are recognized worldwide by competitors and others who demand the best from what they drive. And, whilst some gear sets will perform well for a given period, PPG’s design, testing, development and engineering ethos ensures its products will continue to perform long after others have failed.
Many of PPG’s gear sets are specifically designed to directly replace manufacturers’ OE gear sets. In these instances, the upgrade has to fit perfectly inside the standard gearbox casings, as well as correspond with exiting bearings and clutch mechanisms. In some cases – when standard ratios are retained – the PPG gear set must also be compatible with the original ECU and therefore eliminate the need for a software re-map. Wherever possible, PPG aims to design a gear set that retains the original gearchange mechanism or linkages without modification, which means that installation becomes a straightforward, like-for-like exchange operation.
In contrast to other brands of replacement gear sets, PPG’s synchro kits see no increase in noise levels to that of the standard items. This feature makes them a perfect choice for owners who use their cars for day-to-day journeys on the road, as well as for track days or even competition.
PPG has been manufacturing sequential-shift gear systems for some time, offering teams and drivers the opportunity to increase performance by converting from H-pattern gear-shift configurations. Applying the same no-compromise philosophy to the manufacturing processes and the materials used sees PPG’s sequential systems offer drivers fast and effortless shifting. For its latest sequential systems, PPG has installed industry-leading Gill Blade 360° rotary position sensors for extremely accurate measurement and indication. Integrating with modern 32-bit ECUs to provide closed loop strategies, shifts can be executed in less than 45ms, a speed of operation that is usually only found in F1-type applications.
