Spool Cross Pin GM 7.5 10 Bolt

The Spool Cross Pin GM 7.5 10 Bolt from ALLSTAR PERFORMANCE is a precision differential component engineered for GM 10-bolt rear axle assemblies equipped with a 7.5-inch ring gear. This steel cross pin is the critical pivot element that supports the spider gears within the differential carrier, directly controlling torque distribution between the left and right wheels during acceleration and cornering. Proper cross pin installation and material quality are essential for reliable differential function under load, particularly in performance and heavy-duty applications.

Manufactured to ALLSTAR PERFORMANCE specifications, this cross pin is dimensioned at approximately 4 inches in overall length with a 0.85-inch nominal diameter, precision-machined to ensure proper fit within the GM 10-bolt differential carrier. Steel construction provides the hardness and shear strength required to handle engine torque without deflection or premature wear. Correct cross pin tolerance is critical—loose pins allow spider gear play, causing clunking during acceleration and reducing differential efficiency, while interference fit can restrict spider gear rotation and cause binding.

This component serves builders, restoration specialists, and powertrain technicians performing differential rebuild, repair, or upgrade work on vehicles with GM 10-bolt rear axles. Whether replacing a worn original pin during routine maintenance or sourcing components for a custom differential setup, this ALLSTAR piece is a direct replacement engineered for the 7.5-inch ring gear configuration. It is sold individually to support single-unit replacement needs or inventory stocking for service shops.

The GM 10-bolt differential is found in many light-duty and mid-range trucks and vehicles spanning several decades of production. Cross pin condition directly affects differential longevity and performance characteristics; worn or damaged pins are a common cause of clatter and efficiency loss in older or high-mileage vehicles. Sourcing OEM-spec or equivalent replacement pins from trusted manufacturers like ALLSTAR ensures restoration quality and proper differential function.

Part number ALL68167 is the definitive specification reference for this product. Always verify fitment with your vehicle's rear axle configuration and ring gear size before ordering.
