BBF 429-460 Xtreme 4x4 Hyd. Cam X4262H

The BBF 429-460 Xtreme 4x4 Hydraulic Cam X4262H from COMP CAMS is purpose-built for Big Block Ford applications demanding both street and off-road capability. This hydraulic roller camshaft serves 429 and 460 cubic-inch engines where traditional solid lifter designs create complexity and require frequent valve adjustments. If you're building a 4x4 truck engine or performance vehicle that needs reliable, low-maintenance valve actuation without sacrificing aggressive lift and duration profiles, this cam delivers the precision engineering that separates serious builds from budget compromises.

Hydraulic roller technology eliminates valve train noise and wear that plague solid lifter designs, while maintaining the aggression you need for high-RPM power bands. COMP CAMS engineered this profile specifically for the Xtreme 4x4 application, meaning the lift, duration, and overlap characteristics optimize torque delivery for low-speed truck pulling, hill climbing, and rock-crawling scenarios where predictable power matters more than peak horsepower alone. The roller design reduces friction losses compared to flat-tappet alternatives, improving overall engine efficiency and reducing heat generation during extended operation—critical when running in challenging terrain or towing.

This camshaft is ideal for off-road enthusiasts and classic truck builders who prioritize reliability and driveability over competition-only performance. Installation requires proper synchronization with your existing hydraulic lifter system and confirmation of clearance in your engine bay; COMP CAMS recommends consulting your vehicle's technical specifications or a qualified engine builder to ensure compatibility with your specific 429 or 460 block, intake manifold, and cylinder head configuration. Pair this cam with matched valve springs and quality pushrods to maximize longevity and prevent valve float at higher RPM ranges.
