Rockerarm shaft springs have been preferred by most over locating clamps. Springs are trouble free, require no attention and allow you to service the engine without the worry of leaving a screw untightened. Coiled from music wire they provide 7.5 pounds of pressure at 1.950” height. This pressure is slightly higher than the common spring. Rockerarm shaft shims are stamped from 1085 spring steel and heat treated for wear resistance.
