4.29 Strange Billet Case
Strange Billet Case and Billet Pinion Support offers unmatched strength to weight combination to withstand the most brutal Drag Racing applications. The case is manufactured from 7075-T73 aerospace aluminum that offers superior strength and is highly resistant to stress corrosion. After initial rough machining, the case is vibratory stress relieved, afterwards, it is solution heat treated and artificially overaged. The .650” thick mounting flange coupled with the raised cross rib design provides a solid structure to maintain proper alignment of the ring and pinion. Unique wrap around style main caps enhance strength and stiffness. Each cap is retained by four AISI 8740 steel bullet end studs. The tail bearing area has massive wall sections to firmly retain the oversized tail bearing. A large oil scavenging channel directs additional lubrication to the billet pinion support. The billet case comes 4.29 gear 10" gear set. Also includes computer pickup.
