Transmission Input Sha
fts

The Torsional Input Shaft works like a torsional spring bar, twisting and returning to totally eliminate breakage while reducing shock loads to the gear train. Designed to fit either the Powerglide or TH400 splines, these shafts are available for V8 and 6-cylinder carriers.

In addition to our precision-machined torsional shafts for PG, TH350 & TH400, Ford C-4, C-6 and AOD, we offer special extreme-duty models for the PG and TH400 made of Vasco steel. This material is exceptionally strong and resilient to withstand the most severe torsional shock.

Our Super Shaft (#207148 & #207149 - Patent #6,892,533) is the only ringless Powerglide input shaft that still provides the OEM lube circuit to properly lubricate your transmission and maintain proper converter charge pressure for peak performance. Machined form 315,000 PSI tensile strength steel alloy in full 1" diameter. Requires special stator support tube.
