Traxxas Solid Axle 6061-T6 Aluminium Blue-Anodised RC Spool - 7581

The Traxxas TRX7581 spool is a solid axle replacement unit machined from 6061-T6 aluminium and finished in a blue anodised coating, designed for Traxxas RC vehicles that use a locked rear differential setup. A spool replaces the differential, locking both rear wheels to spin at the same speed simultaneously, which is a common setup for drag racing and straight-line bashing where maximum traction transfer matters more than cornering flexibility. The blue-anodised 6061-T6 aluminium construction offers a more durable alternative to the standard plastic differential housing parts found in many stock builds.
