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

Based on an ultra-durable, one-piece forging, Sonnax Smart-Tech input shaft and piston kits have a hub with longer front clutch splines. Combining longer splines with a thinner billet aluminum direct piston allows for one extra OE thickness direct friction plate, while keeping original thickness steels, backing plate, original retaining ring and OE clutch clearances.

Sonnax premium planetary assemblies are available in various configurations to meet different build requirements. The output shaft is available in the OEM length or short length, and the billet-machined drum flange in 12-tooth or 24-tooth. They are a big step up from standard case-hardened and tempered gears. Sonnax's top-quality racing gear material (SAE9310), combined with a freeze-tempering process (-150 degrees F), results in gears with improved grain structure and stability--tougher and more resistant to wear. Sonnax premium planetary sets are fully assembled and ready to install.
