VW Differential Upgrades
At Wayne Penrose Volkswagen, we can upgrade the differential in
your VW Beetle, VW Kombi, Karmann Ghia, Type 3 and more.
What does the differential do in my VW?
The purpose of the differential in your aircooled VW, is to provide torque to the rear wheels, while still
allowing them to rotate at different speeds from each other. This is necessary when your VW is cornering,
as the outside wheel will travel a further distance than the inside wheel, hence it must travel faster.
How will a differential upgrade benefit my VW?
There are 2 main parts to a differential that can be upgraded:
- The ring and pinion gearset
- The differential centre
The ring and pinion gearset is the final gear ratio between the engine and the rear wheels. By changing
this ratio, we can lower the cruising RPM of your aircooled VW. This allows
your VW to comfortably cruise a higher speed for the same engine RPM. It can also improve fuel economy,
reduce engine noise and benefit engine longevity.
To see what difference a differential upgrade can make to your VW, you can use our
VW differential calulator.
Please note that this calculator assumes
the most common variation of transmission fitted to the model selected. As these VW's are over 40 years
old, there is no guarantee that your VW is fitted with its original transmisison or the exact variation
used in this calculator.
This calculator should be used as a guide only to see what a differential upgrade can do
for your VW.
Apart from changing the final ratio, an upgraded ring and pinion will also have increased strength
to benefit high performance applications.
The differential centre can be upgraded for performance benefits. The standard VW differential
centre contains a set of 2 spider gears. These gears are responsible for
driving the rear wheels, while still allowing them to rotate independently from each other. The
differential centre can be upgraded to contain 4 spider gears for increased strength.
For even higher performance applications, a Limited Slip Differential (LSD) can be fitted.
A Limited Slip Differential still allows the rear wheels to rotate independently from each other
when cornering, but stops the issue of 1 wheel losing traction under heavy acceleration,
a problem that occurs with open (non LSD) differentials.
