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.
