SUPERWINCH OVERDRIVE
Kit Part No. 811 / RTC8020
for the

with standard gearbox





Superwinch (formerly Fairey), Bearmach and Santana


have ceased manufacture of Series Land Rover overdrives.
Superwinch spare parts are still available to U.S. service shops.

OVERDRIVE BENEFITS

An overdrive is like adding a 5th gear to a 4 speed gearbox. It does this


by reducing the final drive ratio by 0.782:1. As a result your Land Rover
will gain a speed increase of up to 27.88%, that's an increase from 55
mph up to 70 mph. Of course the drive ratio will not result in a linear
extension of speed as other factors come into play, such as wind
resistance of the vehicle.

An overdrive can be thought of as increasing fuel economy by up to


27.88%. That's like paying $1.50 a gallon at the pump for fuel priced at
$1.90. If you buy 1,000 gal a year, you could save up to $400 annually.

Best of all, an overdrive reduces wear and tear on the motor and driveline
components of your vehicle over the same distances traveled. The RPM's
are reduced which cause noise levels to be significantly reduced and your
Land Rover seems not to be working as hard. Of course, best results are
achieved with a fit Land Rover, not a tired or worn out vehicle.

An overdrive can essentially increase all the gears, including reserve.


Therefore a 4x1 (4 forward, 1 reverse) gearbox can now be 8x2. The
higher forward gears can be considered split gears that allow for a more
precise selection of an intermediate gear. An experienced driver can
better match engine performance and RPM for varied road speeds and
terrain conditions.
