JIMS' ultimate clutch adjusting tool is a single fit-for-purpose adjustment tool that does the work of three or four separate tools that aren't task-specific. It "allows the technician to quickly and accurately tighten the jam nut without changing the adjuster position. Our custom socket driver allows the hex key to work through the driver and the ergonomic handle stores the key when not in use." For all Big Twins '85 to present, including most aftermarket lock-up and slipper clutches. JIMS USA, www.jimsusa.com
