Sonnax Clutch Hubs

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.

These hubs have been designed to accept up to six clutch plates, but will function properly with fewer plates.

Sonnax Extreme-Duty Clutch Hub and Intermediate Shaft Assemblies

The ideal upgrade for performance vehicles with the GM 6L80 or 6L90 transmission, Sonnax extreme-duty 4-5-6 clutch hub and intermediate shaft guarantees maximum protection against shaft breakage. The unique hub design improves oil flow and accepts Powerglide-style frictions to optimize clutch durability. In place of the 2-piece shaft/hub, Sonnax uses a much stronger, one-piece design that eliminates the OE assembly's weak, welded connection. It is custom forged from ultra-high-strength 300M billet steel, and then heat-treated and shot-peened for added durability. This combination of features guards against broken 4-5-6 hubs and the risk of rear splines shearing off.

Sonnax Clutch Hub Shims

Sonnax clutch hub shims allow hub end play adjustment with a mix of various forward clutch components. These 3-shim sets permit you to limit hub end play, which is beneficial when optimizing the high clutch pack stack-up. The Sonnax shims fit between your small wear plate and drum to lift the hub out of the drum--reducing end play between the hub and sun gear flange, while maximizing clutch tooth engagement with the hub splines. This prevents the rear clutch friction disc from dropping off the clutch hub. Reduce and control end play with Sonnax clutch hub shims.

Sonnax Forward Clutch Hub Washers

A pump that's been resurfaced or accumulated shaft spline wear creates excessive endplay of the forward and direct drums. This reduces sealing ring, clutch, bearing, and thrust washer life. Having the ability to shim both the lower unit sun gear addresses these problems. Sonnax offers forward clutch hub washers for a variety of transmission applications. Product benefits: * Washers take up the play between the forward clutch hub and the direct clutch housing, allowing front unit endplay to be reduced * Washers also stabilize the direct drum, reducing delayed reverse and improving 2-3 clutch circuit * Allows salvage of valuable hard parts
