These lightweight mini spools are designed to replace the spider gears in the GM 7.5" differential offering a solid locked rear end. They weigh only 4 lbs.
Coleman GM 7.5 - 26 Spline Full Spool
This lightweight steel spool is designed to fit the popular 7.5"- 26 spline GM rear end. It eliminates the use of mini spools commonly used to lock the stock GM differential. The heavy duty axle retainers eliminate the use of C-Clips. The stock axle c-clip groove must be machined wider to fit the axle retainers. This spool reduces rotating and unsprung weight.
