Description
A spool eliminates differential action entirely, delivering maximum traction by locking both rear wheels together—essential for drag racing, oval track competition, and high-grip applications where consistency matters more than cornering finesse. The Allstar Performance Ultralite design saves rotational mass without sacrificing durability, reducing parasitic losses and improving acceleration response. If you’re serious about straight-line performance, this is the hardware that gets the job done.
