The
Ranger Torque Splitter Two-Speed Overdrive
has been the answer to gear splitting for nearly
two decades. This unit was designed and developed by Warner Gear Corporation in the late 1960s. We
purchased the unit in 1975, and have built hundreds of overdrive units since that time. The design has
changed over the years, but the performance has stayed the same.
If you have a truck equipped with a 4 speed transmission and are having difficulty
keeping the engine RPMs at peak range, then you need a Ranger Torque
Splitter Overdrive. The Ranger simply provides a gear between each of
your existing gears and converts your 4 speed to an "8 speed". When used
as a gear splitter, you will be able to keep the engine RPM loss at a
minimum, thus preventing the usual winding and lugging of the 4 speed
transmission and engine. This works great for both diesel and gas pickup trucks.
With your engine coupled to the Ranger Torque Splitter Overdrive, your power can
now be efficiently utilized with less engine wear, maintenance & downtime, and
dramatically improve fuel economy. A typical example would be a Chevy truck with a V8
engine and a 4 speed transmission that has an engine RPM of 2500 when driving 60 m.p.h. in 4th gear. This same truck, when
equipped with the Ranger Overdrive and traveling 60 m.p.h. in 4th gear overdrive will have an engine RPM of 1825. This is a
drop of 27% in engine RPMs for the same highway speed.
The Ranger Torque Splitter Overdrive has been designed for maximum ease of installation and requires no special tools. The
front of the Ranger simply bolts directly to your existing bellhousing. Your 4 speed transmission indexes directly into the back
of the Ranger. You will be required to have your driveshaft shortened by your local driveline specialist. The Ranger is 7-1/2"
long and will require the relocation of your 4 speed transmission shift lever.
The internal design of the Ranger Torque Splitter Overdrive consists of a T98 synchronizer coupled with precision helical cut
gears. The gear assembly is mounted on roller & ball bearings that will provide a maximum torque range of 420 ft./lbs. Each
unit is furnished with a shift control handle that has been designed for use in most pickup trucks. The splitting of gears does require
shifting of both the stock 4 speed shift lever and the Ranger shift lever. The clutch must be used when shifting the unit.
RANGER II SPEED
The Ranger is currently available in only a 27% OVERDRIVE 27% OVERDRIVE 27% OVERDRIVE 27% OVERDRIVE 27% OVERDRIVE ratio.
The Ranger is compatible with all manual transmissions whether in 2WD or 4WD. Since the location is ahead of the transmission
and transfer case, the overdrive and gear splitting capabilities can be used in 4WD. The installation of the Ranger in your vehicle
will not require the continual use of all eight forward gears. Depending on your requirements, you need not always use all eight
gears. A good example would be when you are in city traffic where you may choose to use only four gears--the choice is yours.
Whether loaded or unloaded, on the highway or in the city, the Ranger offers you the opportunity for a great investment that makes
your truck fit your driving requirements.
