CMS 930 BILLET SIDE PLATE

 

The original 930 differential side cover is made of cast aluminum, not to mention itís 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 diff bearing.Works both upright and inverted!

ALBINS 930 GEARS

 

Stock gear ratios are designed for drivability and fuel economy and not necessarily for best performance.

 

Whether you have a stock motor or one that has been tuned your transmissionsí gear ratios may not be optimum for your driving needs.  Optimizing your gears to match your enginesí power curves can make a huge difference on the track, often resulting in reduced lap times, and can give the sensation that there has been a gain in power.  Alternative gear ratios can make the car more fun to drive or be more drivable.

 

We carry a wide selection of OEM and Albins gears to suit a variety of applications.

 

         1st, 2nd, 3rd or 4thgear sets are $925 per set; comes with new synchro teeth installed
