Schley Tools - GM CUP KIT (UPGRADE KIT FOR 18100)

The GM Cup Kit (Upgrade for 18100 Ball Joint Press) is a must-have add-on specifically engineered for 2000–2010 GM 2500 and 3500 trucks with steel lower A-arms. Standard cup kits don’t fit these models due to limited clearance, but this custom-designed set solves that issue, allowing for quick, safe ball joint removal and installation using the 18100 press.
