Sebring T5 5
Speed .80 Gear Set
Sebring T5 5 Speed .80 Overdrive gear was originally
designed for an Australian Race team over 10 years ago.
Other companies have manufactured gearsets based on
this very design. Due to overwhelming demand, we are
distributing this gearset with competitive pricing and
quality you can expect from us.
for the Ford World Class T5 or any other World Class
T5 using a 28 spline mainshaft. This close ratio 5th
speed gear set is designed for road racing purposes
and will yield a .81 ratio overdrive with a 2.95 ratio
T5 and a .92 ratio overdrive with a 3.35 ratio T5. If
you require this gearset in a General Motors T5 you
can substitute a Ford mainshaft in place of the GM
piece and change your driveshaft yoke.

factory Ford Motorsport aftermarket .80 overdrive set
used a gearset with a tooth combination of 33 teeth
upper and 53 teeth lower. Creating a new set with
less teeth and a .100" larger diameter upper gear,
realized strength improvements. The new tooth
combination of 20 teeth upper and 32 teeth lower
yields virtually the same exact gear ratio making it
very desirable for road race use. (Note: The factory
.80 gear set is no longer available).

Nickel Chrome Moly (SAE 8620) alloy heat treated for

Snug press fit assures concentricity and optimum
Snap ring land is flat ground to maximize load
bearing surface area.
- Helical cut gears for reduced gear noise when in
- Only .100" larger in diameter than factory .80
sets, allows use of stock bearing.
Factory Ford T5 tailhousings only need a small
area opened up for the 5th gear to clear
properly. The area that is approximately .500"
below the bearing land has plenty of clearance.
The area after that (marked with black X's) is
simply ground open with a die grinder.
One can clearly see in the picture that the S80
upper gear cannot fit through the rear bearing
race. Factory .68 overdrive gears can. You must
press this gear onto the output shaft after the
mainshaft is installed in the main case.
