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 Big Input Shaft Kits

Stop worrying about input shaft failure when running the GM Powerglide in the most extreme applications. Sonnax offers the only big input shaft upgrade with custom components designed to work together for reliable performance. Whether you have an existing assembly or start from scratch in the gear ratio of your choice, it's the best way to connect huge power to Sonnax Extreme planetaries for great run after run with minimum downtime. The only way to prevent twist and breakage from massive torque is to increase the input shaft diameter, and the core of the big shaft system is big input shaft kit 353532-01K. The shaft strikes the perfect balance between strength and ease of installation with a 1 1/8 in. diameter and a unique, high-strength spline that still fits through the front sun gear. It delivers 35 percent more strength than standard 1 in. shafts, a dramatic upgrade for racers that want to take full advantage of the lightweight and efficient Powerglide automatic transmission. (Note: The Sonnax big shaft system for Powerglides requires changing to a 35-spline turbine hub.) Kit contents: * Shaft * Clutch Hub Big Shaft features: * Torsional, ringless design * Heat-treated, 300M steel with advanced processing * 35 splines (AOD-style) at converter Clutch Hub features: * 1.500 in. tall hub for use with 10-clutch setups * High-strength chromoly steel * Custom fit for the big shaft
