Many Sonnax clutch hubs are designed for the extra-duty requirements of drag racing with Powerglide and other GM transmissions, for instance. Machined from a high-quality medium carbon steel forging, most hubs will accept five friction discs for the added load capacity needed in high horsepower race cars. All splines and thrust surfaces are precision-machined to exacting tolerances, and the unique lube hole pattern is designed to reduce drag on the friction discs in low gear. Sonnax clutch hubs are also available with or without lightening holes to reduce rotational weight.

Sonnax Line pressure booster kits allow you to shift aggressively and then feel the tranny grab the clutches with more power when it changes gear. The larger boost valves and matching regulator springs raise line pressure progressively as higher pressure is commanded. These kits modify the sensor signal, which causes the computer to create a pressure increase. They're installed between the pressure sensor and vehicle harness using OE-style sealed connectors; no modifications are needed to the transmission.

Upgrade your transmission's clutch pack with Sonnax automatic transmission clutch steels. These premium-quality steel parts give you the best combination of coefficient of friction and performance. Sonnax offers severe-duty clutch steels for use in a variety of automatic transmissions—including racing applications. These steels are available with up to double the number of external teeth as OE. With more teeth engaged, wear should be reduced dramatically. Anti-drag tabs create the maximum clearance between the friction and steel when the clutch is disengaged. Turbulator holes reduce parasitic drag. Combining anti-drag tabs and turbulator holes significantly reduces the heat generated when the clutch freewheels.
