CMS PORSCHE 930 SIDE COVER
The original Porsche 930 transmission differential side cover is made of cast aluminum, not to mention it’s pretty thin. Under load there can be a tremendous force applied to this cover, and it can break, sometimes resulting in a damaged ring and pinion-or worse. Upgrading to a billet side plate will add significant strength and increased reliability to the differential section.
Our design features include:
- A ring gear thrust bolt to reduce ring gear deflection under load
- Ports that can be used for an oil cooling system
- Cross drilled oil passageways for the differential bearing
Comes with (3) 3/4 - 16 O ring plugs.
