Sonnax thrust bearings are replacements for your worn automatic transmission bearings to aid in smooth operation and noise reduction. The bearings act as a guide to help limit any axial movement which can hinder performance. Manufactured to exceed OE specifications for superior quality even under extreme conditions, order the Sonnax thrust bearings best suited for your application.

Sonnax case saver retainers are designed for 1999 and later GM 4L80-E units—and are the only intermediate clutch retaining ring case saver that allows the intermediate band to be retained. The case savers fit over the intermediate band anchor lug inside the case and extends rearward to support the intermediate clutch backing plate retaining ring, preventing case lug blow-out. Over the years there have been a variety of case saver designs, however, all required eliminating the intermediate band, as is often done in drag racing trans-brake applications. Only Sonnax case saver retainers support the intermediate clutch retaining ring yet are thin enough to allow the intermediate band to be installed to provide case lug protection in all applications.

Sonnax knows you want your transmission to shift like a dream. Their automatic transmission bands are extra-wide intermediate bands suitable for heavy-duty, commercial, and 4x4 vehicles. These drop-in replacements provide 15 percent more holding capacity and feature a 60 percent thicker case anchor, decreasing the chance of band failure under severe conditions. (Note: The red-lined version of these Alto bands is designed for high-torque street racing applications. The Kevlar®-lined version is too aggressive for street use and best suited for high performance racing applications.)

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 rubber clutch separators can be used in racing transmissions to help keep clutch steels separated and reduce open clutch drag when the clutch is disengaged. The friction clutch thickness will determine what size separator you need. Gain the advantage by getting rid of disengaged clutch drag with an assist from the Sonnax silicone rubber clutch separators best suited for your application.

Sonnax retaining rings are stamped from high-strength, roll-tempered steel, providing additional muscle to resist deflection better than mild steel OE retainers. Successful ET racing requires consistent transbrake release; that usually means utilizing stiffer springs—which leads to the need for stronger spring retainers that won't be deflected. Sonnax no-flex reverse spring retainers are small solutions to faster transbrake response times.

Sonnax rubber clutch separators can be used in GM TH400 racing transmissions to help keep clutch steels separated and reduce open clutch drag when the clutch is disengaged. Friction clutch thickness determines what size separator you need. Each Sonnax separator in ORCS-070-380 measures .070 in. in diameter—ideal for use with friction clutches about .060 in. thick. Specs: * Material: Silicone rubber * Diameter: 0.070 in. * Length: 0.380 in. * Package quantity: 70

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.
