OEM & Upgrade Replacement parts
Guard Transmissions utilizes the most advanced and
modernized CNC gear-cutting equipment available. All of Guard Transmission's
gears are cut with class AA grade gear hobs and feature the latest F1 gear
profiles. Contact pressure angles are optimized for maximum strength and each
gear tooth has a very prominent “tip relief” placing all contact directly in the
center of the tooth. This special feature eliminates any premature wear found in
all prior gear designs., which typically occurs at the base and tip of each gear
tooth.
All gears offered by Guard Transmissions are shot-peened to Aircraft
specifications, which normally doubles the service life (in medium stress
applications).
Stronger, quieterm longer-lasting. It has always been the goal of Guard
Transmission to offer gearsets that are so superior in quality, that even the
most discerning European race teams would take notice. These gears are now in
stock.
Guard gears feature modern F1 tooth profiles. Helix and pressure angles are
optimized for maximum strength. Each gear tooth has a very prominent “tip
relief”, placing all contact directly in the center of each tooth. This reduces
premature wear, typical in race use. Guard gears are also the only aftermarket
gears to utilize Porsche ® factory German-made synchro teeth, and are the only
aftermarket gears to have been sold directly to Weissach’s racing division.
For high horsepower Turbo applications, we strongly recommend Guard
Transmission's straight-cut synchronized gears (especially in 3rd & 4th
gear positions), available in the above ratios. Guard Transmission's
billet mainshaft sets have a 30% higher torque rating than standard factory
mainshafts, due primarily to the quill-shaft design. This also allows us to
offer input shafts in varying lengths: Standard, “Short”, Turbo, and “Turbo
short”. This design has been adapted by Weissach.
Guard Transmission LSDs are the industry standard in high performance Porsche differentials. Guard Transmission's CNC billet 4340 chromoly bodies are unrivaled for strength and durability. Guard Transmission's assymetrical ramps and proprietary clutches allow for the adjustability and tunability to suit the needs of the weekend track day junkie or pro-race team alike. We’ve spent the last two seasons working closely with BGB Motorsports learning the Caymans inside and out. That sort of pro level racing experience benefits you, the PCA Club Racers and DE drivers. We don’t just ship you a “one size fits all” specification or make LSDs for 2 dozen different marques. Each LSD sold is stacked and configured for a single specific customer taking into account yGuard Transmission's exact chassis, as well as skill and power levels and is backed by 2 decades of transmission experience focused on Porsches and their specific needs.
