COMP Cams Ultra Pro Magnum XD 1.7 ratio rocker arm set for 7/16" stud Ford applications (8-piece) offers rebuildable stud-mount strength. Machined from 8650 steel with a billet pushrod seat insert, these rockers use precision-sorted needle bearings and hardened roller tips to reduce wear while working with most spring and retainer sizes.
