Product Information
CNC machined billet aluminium differential sump for 105 / 115 axle case with increase oil capacity and cooling fin surface area to reduce axle oil temperature.
High horsepower 105s start to suffer from excessively high differential oil temperatures under hard use, this can cause excessive axle noise and premature CWP wear.
The differential sump size & design was originally specced for the early 1300cc Giulietta, this design was run through to the later 105 models unchanged and certainly never intended for the type of BHP or load that so many of us put through the cars today. Excessive whine and backlash noise at the end of long hard drives that go away when the car has rested are classic signs of excessive oil temperatures.
We have designed the differential sump to carry 23% additional oil capacity and redesigned it with a combination of both larger & additional lateral cooling fins (in a similar design to a GTA engine lower sump) to dramatically increase the surface area for airflow and therefore significantly increase cooling efficiency of the sump.
- Fins and sump plug pre-drilled to allow lockwiring.
- Anodised finish
