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 optimises bearing lubrication. Strange offers the Ultra Case assemblies in three different bore sizes.
