The Mini Spool 7.5in GM 10 Bolt 26 Spline from Coleman Racing Products is a precision-engineered differential spool designed for high-performance GM 10-bolt rear axle assemblies. Built for drag racing, off-road competition, and serious street performance applications, this spool locks the differential carrier for maximum traction during hard acceleration. The 7.5-inch diameter and 26-spline interface match OEM GM 10-bolt specifications, making it a direct-fit upgrade for vehicles requiring superior power delivery and wheel hop elimination.
Constructed from hardened steel, the Mini Spool 7.5in GM 10 Bolt 26 Spline provides a solid, no-slip connection between left and right axle shafts. Unlike traditional clutch-type differentials that allow tire slip and power loss during acceleration, a spool delivers 100-percent mechanical lock—both wheels rotate at identical speeds regardless of traction conditions. The compact 4.5 x 4.5 x 5.75-inch footprint and 4.07-pound weight ensure minimal installation complexity while maintaining the structural integrity demanded by high-horsepower powerplants. Coleman Racing's precision manufacturing ensures tight tolerances and long-term reliability under sustained load.
This spool is ideal for dedicated race vehicles, drag strips, and off-road platforms where maximum traction and predictable axle behavior outweigh the need for street-friendly differential action. Installation requires professional-level differential work—proper bearing preload, backlash adjustment, and carrier setup are essential for optimal performance. Verify your vehicle's 10-bolt configuration and spline count before ordering; the 26-spline design fits specific model years and axle codes. Consult technical documentation or contact Coleman Racing directly if unsure of compatibility with your particular GM platform.
