Description
If you’re running an open differential on your GM 12-bolt, you’re leaving traction on the table. The Allstar Performance Mini Spool locks both axles together, eliminating wheel spin and delivering equal power to both sides—critical for consistent launches, cornering grip, and overall drivetrain control. Built from high-strength steel with a protective black powder coat, this spool is engineered for durability in demanding racing and high-performance street applications.
Installation is straightforward on open-style carriers, making this a practical upgrade for anyone serious about maximizing rear-end performance without a full differential swap.
