The ultimate in cup adjusting screws. Adjustments can be made much easier with the exclusive 3mm wrench design. Maximum number of rolled threads for best possible fit and strength. Correctly designed cup for higher lift cams. Shorter overall length to clear valve covers. Lighter weight than the old fashioned slotted type. Individually racked during heat treating to ensure proper hardness and strength throughout. Well worth the cost when you must have the best. Featured in GB 411 high ratio rocker arm sets. Excellent to convert Sig Erson, Autocraft or any other ratio rocker arms with the male 5/16-24 screw to female cup so you can use standard design ball end pushrods. Lets you select pushrod length (GB 424 or 425 pushrod kits) with male ends. Ours feature a 3mm allen type head that provides far more strength and valve cover clearance. |
