GSC R2 Camshafts – 5.0L Coyote Gen 3 2018–2023 Mustang 5.0

Built for ported heads and real track work, the GSC R2 profile drives the Coyote hard to 8,100 rpm with a usable band from 5,800–8,500 rpm. Events are modeled for ported Gen 3 heads flow behavior and correct rocker geometry for high-flow combinations, then cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. Runs on pump gas, race fuel, or ethanol blends (E85/E90). Direct Injection note: the high-pressure fuel pump (DI/HPFP) lobe is maintained to OEM specification—stroke and timing are retained for proper pump operation.

With OEM pistons and deck heights, the full phaser range is typically usable without clearance issues. Use upgraded valve springs (and Ti retainers) set to the tuner’s rev limit; check installed height and coil bind. See install sheet for torque sequence and procedures; prime oiling and fuel (HPFP follower inspection) on reassembly.
