This unique and helpful tool makes adjusting valves quick, easy and accurate. Just set the "L" handled wrench on the rocker arm poly-lock nut and loosen. Slip one of the included "T" handled allen wrenches into the guide and back off the allen bolt. Then adjust the "L" handled wrench until the desired valve tip adjustment is achieved and then lock the allen bolt without moving or disturbing the valve clearance adjustment. Then simply move onto the next rocker arm.
Comes with one padded handled adjustment wrench and two allen "T" locking wrenches.
