The aluminum differential cover provided by Strange certainly adds some visual pop, but its primary benefits are reducing distortion of the differential housing and stabilizing the main bearing caps. This, in turn, helps maintain proper pinion depth and gear backlash. The cover's two load bolts are positioned to come in contact with the center of each bearing cap as they're cinched down, which provides cap preload and reduces the likelihood of distortion. After tightening the 10 cover bolts to 25 lb-ft, Bill torqued the load bolts to 10 lb-ft using an Allen wrench. Next, the jamb nuts were tightened to 10 lb-ft to lock everything in place.
