About the Strange Ultra Case The heavy duty aluminum 9" Ultra Case is engineered to provide better lubrication to the pinion bearings and easily accept 9.00" or stronger 9.50" gear sets. The Ultra Case incorporates a uniquely designed pinion support that coalesces with the case to provide superior ring and pinion life. Four chrome-moly studs are encapsulated by billet caps, allowing for shorter and stronger studs. The tail bearing is larger than factory, which can withstand greater rpm speeds and is secured by a special retainer plate. Strange also offers a lightweight Ultra Case, featuring a taper/ball bearing pinion support. This unique 3.812" bore case incorporates a billet aluminum pinion support that has been pocket milled for reduced weight and embodies a low friction angular contact pinion ball bearing. The case and caps have been modified to further reduce static weight. The lightweight Ultra case/pinion support is 1.75 lbs. lighter than our standard Heavy Duty Ultra Case/pinion support package. Both Ultra 9" Cases provide superior strength through encapsulated cap studs, a larger than stock tail bearing, 12 pinion support bolts and a unique casting design, which provides strength and optimizes bearing lubrication. Strange offers the Ultra Case assemblies in three different bore sizes. Strong enough to endure Pro-Mod, Alcohol & heavy door car applications. Premium grade aluminum Chrome-moly and encapsulated studs Accepts 9" and 9.50" gear sets Notes: OEM or OEM style housings may require modification to the housing. The Ultra case measures the same distance from center line of axle to center of u-joint as all Strange 9" cases
