GEAR VENDORS RACING APPLICATIONS
The Gear Vendors uses a common vertex (cone) Raybstos clutch system. This means
there is no parasitic loss through dragging an unapplied clutch pack. For this reason
the Gear Vendors is the most efficient transmission on the market using less than
1 horsepower per 400.
The Gear Vendors planetary carrier and power flow are ideal for motorsports and contain
a level of engineering that would be hard to justify if it were not that we also
sell tremendous amounts of over the road non-race product. Because of this the UNDER/OVERDRIVE
is a real bargain for racers in performance per dollar.
Customers involved in professional motorsports should contact us at the factory to
ensure you are getting the proper products and that our benefits will be appropriate
for your application. Use the Final Drive Ratios found in the 2-wheel drive section
of this catalog for ratio information.
DRAG RACING Powerglide
The Gear Vendors in combination with the Powerglide is an affordable, reliable,
and very efficient package. This is a superior alternative for most cars looking
to go to a 3-speed. The Gear Vendors .78 to 1 ratio allows you to go to a numerically
higher rear gear to improve your 60ft. times and get it all back with the overdrive.
The reciprocal of our ratio is 1.28 so a car that currently runs a 4.56 rear could
go to a 5.84 without loss of top end. You will have these improvements with reduced
cost, greater reliability, and lower parasitic losses when compared to conventional
3-speeds. The overdrive is switched on with 12-volts and so is easily adapted to
steering wheel buttons or automated through rpm switches. The product is ideally
suited in stock form for cars with 1200hp or less and in this case is virtually indestructible,
literally running for seasons of use without maintenance other than fluid. Cars with
1400+ horsepower can be accommodated but you should call the factory so hydraulic
issues dealing with clutch ramp timing can be properly adjusted for your application.
DRAG RACING 3-Speed AUTOMATIC
Splitting the ratios (especially 2nd-over) is always valuable to the 3-speed
car. 1st over may produce wheel slip and so is not commonly used but 2nd-over keeps
the converter tight and produces torque multiplication right when the 
aerodynamics
are starting to load the car heavily. We’ve never heard of a car that didn’t run
quicker going 1st,2nd, 2nd-over then 3rd. Some heavier cars that don’t want to turn
the engine real hard are also going up to a 1.28 deeper rear gear (the reciprocal
of our ratio) and running 3rd-over for 5 or 6-speeds.
Consistency and E.T. are improved by operating the engine and converter in a tighter
rpm range as well as having more torque multipliers through the run. The Gear Vendors
is one of few products that can improve both. Study the Final Drive Ratio charts
in the 2-wheel drive section appropriate for your tranny make and also read the powerglide
section in this catalog.
DRAG RACING/ROAD RACING with 4-Speed
MANUALS
Gear Vendors makes a kit to fit the Ford Top Loader and Jerico transmissions.
The .78 to 1 ratio gives 28% more top
end to the vehicle numerically and
can be used in a variety of ways for the racer. Since the Gear Vendors can be shifted
without clutching, it is decidedly faster when compared to a conventional shift.
Imagine coming out of a corner or racing down a dragstrip where a foot or two could
be very valuable and you have the option to hit a .78 multiplier under full throttle.
Some drag racers have found that using the overdrive version (popular in road racing)
of the Top Loader with the ability to clutchless gearsplit the wide ratio makes for
a great 5 or 6-speed.
LAND SPEED RACING
For sustained long runs at high rpm we do a couple subtle changes to cut down
the hydraulic flow and relive pressure build. With this configuration we have completed
thousands of miles of testing and racing between 7000 and 1200 rpm and can handle
upwards of 2,000hp.
The super efficiency of the Gear Vendors (parasitic loss less than 1 hp per 400 lend
itself to success in virtually all LSR classes that use a transmission. Wide ratio
transmissions are able to use the gear splitting feature to greatly improve engine
reliability as it comes up through the gears in a tighter rpm range so less time
is spent at rpm’s where the engine may not be designed to run well. On short runs
like Bonneville and other LRS tracks no cooler is needed or recommended for the Gear
Vendors.
OFF ROAD RACING
Because of the variety of terrain and traction it is hard to imagine a sport
more suited for our product than off road. Everyone who has tested or raced with
the product loves it and no one has every broken one off road.
The Factory Ford and GM sponsored guys are able to use exotic versions of Ford and
GM/Hydramatic overdrive 
transmissions provided to their teams. They get
converter lockup choices in a variety of gears, overdrive, and gear splitting (turning
the overdrive on while in the overdrive ratios) to keep the motor in power. But this
is not available to more than a select few because the cost of maintaining these
exotic versions is steep.
Once equipped with a GEAR VENDORS a three speed automatic has 6 available ratios
you can shift through under full throttle. Look at the Final Drive Ratio charts in
the 2-wheel drive section and notice the close ratio aspect of this package. Whether
you are in a Baja sandwash, hitting the apex of a corner at Pikes Peak, or hitting
a jump on a closed course short track, the value of these gears is tremendous. The
truck handles better because you always have the right gear for power. Also, the
transmission will last longer because the torque converter is hooked up all the time.
Mike Lesle Racing (19-desert&stadium championships)
has done testing and been instrumental in our approaching CORR for Pro 2 approval
and we hope to soon be allowed in the series. Mike also runs the product in his Fleetwood
motorhome.
Bryant Hibbs, currently a consultant to ProTruck (Ivan Stewart’s Spec Series) has
years racing his automatic with a Gear VendorsS. “Gear Vendors made all the difference
for our trucks performance in the Baja 1000.”
Craig Stewart won the only event he’s raced with a Gear Vendors. We are working on
becoming a spec item for ProTruck so they can run in a class with our product.
Off Road Racing...highest finishing American Vehicle in
the 2001 and 02 Dakar Rally's (7th & 13th). The Dakar like the Tunisian and Master
Rally's is part of the world Rally circuit dominated by full fledge factory efforts
from Mitsubishi, Renault, Nissan, etc.
March 2001 - the GEAR VENDORS equipped Ford ProTruck won the overall for 1st
place in the Tunisian Rally with driver Bruno Saby. Congratulations to, ASM racecars,
Craig and Ivan Stewart and everyone else involved in a fantastic result in the 7500
mile race.
Off Road racing is full of great people with talent and ingenuity, but they won’t
necessarily brag about stuff that’s working really well. For this reason Gear Vendors
offers Off Roaders a full one year warranty and a 30-day money back guarantee, so
you can actually race or test with our product and still get your money back. Try
it and you’ll see why we can make this offer.
E.V. RACING
Some people are surprised to learn that we’ve been involved in Electric Vehicles
since the mid ‘80s. Gear Vendors has designed a built several transmissions for Chryslers
TEVan project (electric version of the Dodge Caravan/Plymouth Voyager), Georgia Power
and a number of universities entered in research and development or hybrids and alternative
fuel cars and trucks.
Electric racing interested us because of the high sustained rpm and the absolute
need for efficiency. BGSU’s (Bowling Green State University) Electric Falcon was
the winner of the Phoenix Grand Prix at PRI. The Lincoln motor turns the Gear Vendors
1200 rpm for sustained runs; A fairly impossible task for most transmissions.
Check out the unlimited horsepower warranty and money back guarantee and the simple installation in the dimensions section. Then order give us a call..
In addition to the overdrive units, we also provide an impressive
