Strange Engineering N1901 Lightweight Aluminum 9" Ford Center Section Case 3.062" Bore

The Strange Engineering N1901 is a lightweight aluminum center section case designed for Ford 9-inch rear axle applications where maximum weight reduction is critical. Machined from high-tensile strength aluminum alloy, this case offers significant weight savings over traditional cast iron housings while maintaining exceptional structural integrity for racing applications.

Key Features:

• 3.062-inch carrier bearing bore size for 31 or 33 spline axle configurations
• High-tensile strength aluminum alloy construction for superior strength-to-weight ratio
• Forged aluminum main bearing caps for maximum durability
• Solid steel adjuster nuts for precise ring and pinion setup
• Saves approximately 20 lbs compared to stock Ford iron cases
• Designed and machined by Strange Engineering, cast in the USA
• Includes adjuster nuts and pinion support bolt mounting provisions

This lightweight aluminum case is ideal for drag race applications including Super Comp dragsters, altered vehicles, and lightweight race cars where unsprung weight reduction is paramount. Note that due to aluminum's reduced rigidity compared to cast iron, this case is recommended for lightweight vehicles with relatively low impact loads. For heavy, high-horsepower, or street/strip applications, Strange Engineering's HD Pro Aluminum or Pro Iron cases are recommended alternatives.

Compatible with Strange Engineering's full line of 9-inch Ford components including spools, differentials, gear sets, and pinion supports. Can be installed in factory or aftermarket Ford 9-inch housings.
