Proforged 221-10013 2in. Drop Spindle Kit | 1964-1972 GM A Body, 1967-1969 GM F Body, 1968-1974 GM X Body

Giving your classic GM A-body, F-body, or X-body a lower stance, improved handling, and modern disc brake capability doesn't have to require a complicated suspension overhaul. Proforged 2" Drop Disc Brake Spindles provide a straightforward way to achieve all three, delivering a 2" front drop while supporting factory-style and aftermarket disc brake systems. Built around a one-piece forged steel design, they provide a strong foundation for restorations, upgrades, and performance-oriented street builds.

IMPROVED LOOKS AND HANDLING

Lowering your vehicle is one of the easiest ways to improve both appearance and performance. A 2" front drop gives your A-body, F-body, or X-body a cleaner, more aggressive stance while lowering the vehicle's center of gravity, helping improve handling and responsiveness. Proforged drop spindles make it easy to achieve both with a single upgrade.

DISC BRAKE COMPATIBILITY

If you're looking to update your classic GM from factory drum brakes, Proforged Drop Disc Brake Spindles provide one of the easiest paths to modern disc brake compatibility. Designed for use with factory-style disc brakes and many aftermarket brake kits, they give you the flexibility to restore your car with factory-style components or upgrade to a more capable braking system. Vehicles already equipped with disc brakes can take advantage of a straightforward spindle swap while gaining the added benefits of a lower stance, improved handling, and forged steel construction.

FORGED FOR STRENGTH

Manufactured from one-piece forged steel, precision machined, and protected by a durable E-coat finish, Proforged drop spindles are built for long-term durability and reliability. Forged construction provides exceptional strength, while precision machining helps ensure proper fitment and consistent quality. The durable E-coat finish helps resist corrosion and maintain a clean appearance for years to come.
