The Brian Crower Stage 3 camshaft for 1965–1990 Jeep Wagoneer 4.0L/4.2L inline-six is a rock-crawler spec profile intended for low-speed torque and heavy-load off-road use. It supplies an aggressive cam timing optimized for crawl performance while remaining a direct-fit replacement for compatible AMC inline-six engines when installed with the appropriate supporting valvetrain components.
