The Ranger Torque Splitter is an auxiliary gear box that bolts in front
of the standard Chevy, Ford and Land Cruiser 4 speed transmissions. This
fully synchronized unit allows you to split your gears at any time.
Just push in the clutch, grab the Ranger's shift lever, (You will have two
shifters: one for your main trans and one for the Ranger) and shift. At
any speed. The unit is available in either a 27% overdrive or a special order 17%
underdrive.
(Please call for availability on the 17% underdrive models.) Through
the years it has gone through several design changes. Today's unit is cast
aluminum, measuring 7-1/2" long. The gears are helical cut and the
shifting mechanism is a short throw manual shift. The unit is built to
handle 420 ft./lbs. of torque and has a G.V.W. rating of 25,000 lbs. This
unit is ideal for towing applications or improving gas mileage by lowering
the RPMs.
The unit weighs 80 lbs. and is easily shipped via UPS. It has a 1 year
unlimited mile warranty from the date of shipment.
Typical Installation Info
Installation will involve moving the transmission back 7.5". Your
stock clutch components will work, as will the stock clutch linkage Floor
board modification will be required for the shifter relocation, and for
the shifter stick coming up from the Ranger. The crossmember will need to
be relocated 7.5" back (Often this merely requires drilling holes to
bolt it in in the new location, however your truck should be examined to
verify this. In some cases light fabrication is required to build a new
crossmember. You will need to take your driveshaft(s) to a
driveshaft shop and have them shortened / lengthened) appropriately. That
is pretty much the extent of it.
Ranger
vs. NV4500 conversions: The choice between an NV4500 conversion and
adding a Ranger in a truck with an existing 4 speed: The NV4500 will result
in 5 forward gears, 5th being overdrive. Both units have 27% OD, so no
difference there. Ranger system roughly $700-1000 less costly. Ranger system
allows gear splitting, and when used in conjunction with a
granny-gear wide ratio trans allows gears between the gears, effectively
doubling available ratios. Ranger plus granny 4 speed noisier than NV4500.
NV4500 is a more civilized trans. only 1 stick, rather than 2 to deal
with.
CHEVY
760001-NV4500L-GM
In Front of GM NV4500 1996-and
up
760001-NV4500E-GM
In Front of GM NV4500 1993-95
760001M-27
1947-1966 Chevy Overdrive with
a 4.686" index
760002M-27
1967-1987 Chevy Overdrive with
a 5.125" index
Note: These units are for Chevy stick transmissions and will bolt
directly to the specified transmission and matching bellhousing with only minor modifications. Driveline and floorboard modifications are required.
FORD
760010M-27
1965-1970 Ford Overdrive, for
use with transmissions having a
5.125" index diameter.
760014M-27
1971-1987 Ford Overdrive. for
use with transmissions having a
4.848" index diameter.
Note: These units are for Ford 4 speed transmissions and will bolt
directly to the 4 speed and bellhousing with only minor modifications. Driveline and floorboard modifications are required.)
Toyota LAND CRUISER
1974-1986 4 speed models
with Chevy engine
Overdrive: PN 760024M-27
The ranger overdrive bolts
between a GM 4speed bellhousing and the stock LC 4speed transmission.
1963-1973 3 speed models with
Chevy engine
As above, works with a stock GM
4spd bellhousing. The earlier 3 speed Land
Cruiser trans can be mated to the Ranger Torque Splitter by using a special
retainer,
PN 716222 with Overdrive PN 760001M-27.)
1987 and newer Land Cruisers
with GM Engine
The Ranger
can be installed on 1987 and newer Land Cruisers. On these applications we
have found a few odd size input shaft bearings that Toyota used. In order
to use our overdrive unit, the front input shaft bearing of your
transmission must be measured. (This will verify what bearing index is
necessary - a 3.544" diameter is standard.) If your bearing diameter
is 3.625", a special rear plate can be machined for this application.
LC V8 Conversions
The overdrive design for the Land Cruiser makes an ideal conversion. The
unit can be built to bolt directly to a standard GM or Ford Bellhousing at
the front, LC transmission at the rear, and, at the
same time, positions the V8 engine in the correct location to avoid any
driveshaft modifications.
Land Cruiser retaining stock
"F" series motor - It is possible to build a Ranger to
this engine by using a stock Toy LC 3sp bellhousing. This (involves a bit
of custom machining on the Ranger). This Ranger then can be bolted to the
Stock 4speed, stock 3 speed. Looks like H55 5speed should work. Also
possible: GM SM 465, Ford Transmissions such as the
T18,T19 or NP435. NOTE: In a short LC applications such as FJ40 - check your
driveshaft length - this will move your Tcase back appx 7 inches.
Land Cruiser SM420/465 applications
The Ranger Overdrive can be built to act as the adapter
between the factory bellhousing and an SM420 or 465 transmission
DODGE
Ranger for Dodge NP435
This is not available as an off the shelf product. It can be done,
however, by jumping through a few hoops:
1st, the Dodge NP435 input shaft has a stick-out of 8-3/8". This
input shaft will need to be swapped for the shorter Ford NP435 input shaft
in order to fit the internals of the Ranger.
In order to put the Ranger to the Dodge bellhousing a new Ranger input
shaft and case will need to be made up. Also, a new Ranger adapter plate
to match the Dodge case (bolt pattern & index diameter) will need to
be made. If you are willing to send us a Dodge NP435 bell housing, Dodge
NP435 input shaft & bearing retainer, we can look into making the
required Ranger parts.
