12 Bolt Aluminum Cover - Added strength or no?

320 Views 7 Replies 7 Participants Last post by  joe_padavano
Hey guys. This is for all you Chevy truck 12 bolt experts out there. Do you believe that a cover such as this adds any real overall strength to a 12 bolt? From the vendor:

Rim Automotive wheel system Bicycle part Silver Watch

"Made from 356-T6 cast aluminum, these girdles incorporate a reinforced crossbar. The crossbar houses the load bolts that apply pressure to the bearing caps. This feature, along with the thick casting, prevents bearing cap deflection under severe loads. Which in turn greatly reduces or eliminates (in most cases) bearing cap fatigue and failure. "

Thoughts?

Thanks,

Brent

The truck version of the 12 bolt uses a 10-bolt type pinion shaft/bearing. I have a feeling that the pinion is your weak point. I don't think adding a girdle is going to prevent explosions since the carrier bearings are plenty beefy. Unless you're launching with wrinkle walls and 500 lb-ft, I wouldn't worry about it.
