Pro series 3 Diesel universal valve opening fixture has a 32 inch long tee bar, works good for long cylinder heads like gas or diesel truck and tractor inline 6 cylinder heads when flow testing on flow bench. Tee bar mounting blocks heavy duty and larger than are standard and has same dual mounting bolt pattern. Can be bolts to valve cover rail or flat surface with threaded holes. The 3200XB save the flow bench technician time, by setting the tee bar once and moving only the x axis bracket end for end on the cylinder head when flowing testing ports. Teclock dial indicator reads .001″ increments up to 1.000″ lift. Please e-mail with questions
