COMP Cams Ultra Pro Magnum XD 1.7 ratio rocker arm set for Ford (3/8" stud) is a direct-fit option for 289, 302 and 351 Windsor applications. Machined from 8650 steel and fitted with a billet pushrod seat insert, these fully rebuildable rockers use precision-sorted needle bearings and hardened roller tips to reduce wear and work with most spring and retainer diameters. XD geometry benefits from FEA and CAD development for improved stiffness and MOI.
