Ultra Case Package

(450+ hp, spool only)

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” Drag Competition gear sets. The Ultra Case incorporates a uniquely designed pinion support that connects with the case to provide superior ring-and-pinion life. Four chromemoly 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.

We also offer 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 9” Ultra 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. The Ultra Case and Drag Competition gear set are designed for drag-racing purposes only.
