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 1.58/1.65 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” dia. and a unique, high-strength spline that still fits through the 1.58/1.65 front sun gear. It delivers 35% more strength than standard 1” shafts, a dramatic upgrade for racers that want to take full advantage of the lightweight and efficient Powerglide transmission.
