AMC Xtreme Hydraulic Cam X4250H

The AMC Xtreme Hydraulic Cam X4250H is designed for serious AMC engine builders and performance enthusiasts seeking to maximize power and reliability. This hydraulic flat-tappet camshaft is engineered to provide the aggressive lift and duration necessary for significant horsepower gains in both classic and modern AMC V8 applications.

Featuring hydraulic valve lifter compatibility, the X4250H ensures consistent valve train geometry and simplifies installation compared to solid lifter designs. Its precision manufacturing and high-quality materials contribute to repeatable performance and extended service life across thousands of engine cycles. The cam's aggressive profile is optimized for peak power generation while its hydraulic design self-adjusts for thermal expansion, eliminating the need for manual lifter preload adjustment.

Ideal for AMC 258, 304, 343, and 401 cubic-inch engines commonly found in Jeep, Javelin, and AMX platforms, this camshaft provides a solid foundation for enhanced power output while maintaining drivability. Installation requires a properly prepared block with correct lifter bores and compatible pushrods, and professional engine builders recommend verifying valve clearance and spring pressures during the installation process.
