9in Floater Bare Housing 2.5in GN Snouts 58in Ctr

The 9in Floater Bare Housing 2.5in GN Snouts 58in Ctr from ALLSTAR PERFORMANCE is a precision differential housing designed for serious drag racers, circle-track competitors, and high-performance street builders who demand reliability under extreme torque loads. This bare floater housing serves as the foundation for custom rear-end builds where weight distribution, strength, and tuning flexibility are critical to lap times and elapsed times. Whether you're assembling a dedicated race car or upgrading an existing platform, this housing accommodates the specific geometry needed for maximum traction and predictable handling characteristics.

This 9-inch floater housing features a 58-inch center-to-center measurement and 2.5-inch GM-style snouts, making it compatible with standard aftermarket axle shafts and brake packages common in racing applications. The floater design—where both axles float independently within the housing rather than being splined to a solid center section—allows for better weight transfer, reduced tire scrub on cornering, and improved launch characteristics off the line. At 43 pounds, this bare unit provides a lightweight starting point for builders who will add their choice of internals, locking differentials, and gear ratios tailored to their specific racing class or performance goals.

Competitors and enthusiasts building 9-inch differentials benefit from the bare housing approach because it allows selection of locker type, gear ratio, and carrier bearing preload without compromise. This housing is ideal for NHRA competitors, road-course racers, and engine-swapped platforms where axle geometry must match custom suspension geometry. Installation requires professional setup knowledge—bearing preload, backlash, and pinion depth must be dialed in precisely to ensure longevity and consistent performance. The 11.5 x 7 x 58-inch envelope fits most standard frame rails and transmission tunnel configurations used in modern race car construction.
