■ Stop worrying about input shaft
failure when running the GM Pow-
erglide in even the most extreme
applications. Sonnax offers the only
big input shaft upgrade with cus-
tom components designed to work
together for reliable performance.
The system was a big success when
introduced in 2017 for Sonnax 1.58
and 1.65 ratio planetaries, and the
company recently expanded cover-
age to include 1.69 and 1.80 ratio
builds. Whether you have an exist-
ing assembly or start from scratch
in the gear ratio of your choice, it’s
the best way to connect huge power
to your transmission 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 bal-
ance between strength and ease of
installation with a 1-1/8" dia. and a
unique, high-strength spline that
still fits through the front sun gear.
It delivers 35% more strength than
the best 1" shafts, a dramatic up-
grade for racers that want to take
full advantage of the lightweight and
efficient Powerglide transmission.
Mating up to the shaft are Son-
nax’s big shaft stator tube kit and
rear sun gear kit, every component
refined for maximum durability.
These big shaft parts work flaw-
lessly with Sonnax Extreme plan-
etary assemblies and Extreme
strength output shafts to deliver
unrivaled performance. A simple
change to a 35-spline turbine hub
is all that’s required to level up with
this unique system.
Selecting the right components
for a big shaft system is easy. Decide
what gear ratio you want to run —
1.58, 1.65, 1.69 or 1.80 — and wheth-
er you want to upgrade an existing
Sonnax planetary assembly or start
from scratch. If you’re upgrading,
you’ll need the big input shaft kit,
stator tube kit and a rear sun gear
kit. A brand-new build requires
those three components plus a Son-
nax planetary assembly and 27- or
32-spline output shaft.
