The Team Losi LOSA99168 Clutch Tool all but eliminates the pinched fingers and aggravation associated with working on the clutch shoes and springs of a .21 to .30 engine. This handy clutch tool has a pivoting arm with an extra long metal flap that holds the clutch shoe and retracts the spring for removal. The arm can also be flipped over to correctly position/push the shoe on while retracting the spring during installation. The Team Losi clutch tool is lightweight and compact easily fitting in your tool kit. All 1/8 scale on-road and off-road racers as well as big block monster truck owners will find this tool a must have.
