ARP 135-7121 Rocker Arm Stud Kit for 7/16 Rocker Arm Stud Kit ymm_48 The specially alloyed “ARP 300”Rocker Arm Stud Kit (135 7121) by ARP. The engineers at ARP spent quite a bit of time developing these highly effective, unique oil pan studs. Theyre designed to make it as easy as possible to install a pan and seal it properly. Youll note that the studs have a radiused bullet nose that serves to locate the pan rails, then allow the nuts to be easily installed without the worry of cross threading. For those who prefer bolts, ARPs got you covered, too.
