This Allstar Performance mini spool is a 26-spline steel mini spool built for GM 10-Bolt 7.5in differential housings, the smallest of the GM 10-Bolt housings in this lineup. It replaces the spider gears inside the stock 7.5in carrier, locking both axles together for full lockup while retaining the factory ring gear and carrier.
Compatibility: Fits GM 10-Bolt 7.5in housings using the stock carrier and requires matching 26-spline axles. This 26-spline count is different from the 28-spline GM 10-Bolt mini spools ALL68160 (8.5in) and ALL68162 (8.2in).
