Mini Spool-GM 7.5 26

The Richmond Mini Spool-GM 7.5 26 is a performance differential component engineered for drivers serious about maximizing traction and handling on GM 10-bolt rear axles. This steel spool replaces the factory open differential, locking both wheels at the same rotational speed to deliver consistent power delivery under acceleration, cornering, and load transfer. Whether you're upgrading a street machine, weekend track car, or off-road vehicle, the mini spool eliminates wheel spin and delivers the immediate response that separates competent handling from truly sharp vehicle dynamics.

Constructed from durable steel, the mini spool features a 26-spline design that interfaces directly with OEM axle shafts on GM 10-bolt differentials, providing a bolt-in upgrade path with zero modifications to existing drivetrain geometry. The spool's fixed-lock design eliminates the rotational lag and compliance inherent in clutch-type limited-slip differentials, resulting in immediate torque vectoring and predictable weight transfer during spirited driving. Unlike helical or clutch designs, the spool's simple mechanical construction offers reliability without maintenance concerns, making it an ideal platform upgrade for vehicles seeing frequent aggressive use.

The Richmond Mini Spool-GM 7.5 26 is the choice for serious enthusiasts running carbureted or modern EFI small-block Chevrolet platforms in first and second-generation F-body Camaros, second-generation Firebirds, A-body intermediates, and S-10 compact trucks equipped with GM 10-bolt axles. Installation requires only basic hand tools and axle service experience; technicians should verify spline compatibility and ensure proper bearing preload during installation. This component is not recommended for vehicles prioritizing daily-driver comfort, as spool-equipped vehicles exhibit tighter turning radiuses and slightly increased tire wear during low-speed cornering.
