the first time ever, ATI is proud to introduce 1.64
ratio gearsets for ATI Superglide 4 Transmissions and
1.66 ratio Gearsets for the standard 19 spline Powerglide
input shaft. The new 1.64 ratio Vasco straight-cut gearsets
feature a Superglide 4 Sun Gear (27 spline 1-3/8th input
shaft) and a Turbo 400 Output. They're available in
both standard 28-inch (#204900VS) and shorty 18-inch
(#204898VS) lengths with a "Lightweight option" (28” #204900VS-LWT,
Shorty 18” #204898VS-LWT) that includes a billet aluminum
carrier and the 28” features a gun drilled output shaft.
For our non-Superglide racers, ATI's new 1.66 ratio
gearset comes with a standard Powerglide 19-spline input
shaft Sun Gear and standard 27 spline Output with 12
DP Vasco gears in a bolted carrier. They are available
in standard 28-inch (#204897V) and shorty 18-inch (#204896V).
