Xtreme Energy Hyd. Cam - BBM XR286HR-10

The Xtreme Energy Hyd. Cam - BBM XR286HR-10 from COMP CAMS is a precision hydraulic roller camshaft engineered for big-block Mopar enthusiasts seeking aggressive street and strip performance without sacrificing drivability. This cam is built for builders and mechanics who demand a balance between raw power and practical valve actuation, making it ideal for 440 and 454 big-block applications where hydraulic lifter reliability meets high-lift, long-duration aggression.

COMP CAMS' Xtreme Energy series delivers advanced cam lobe geometry optimized for peak cylinder pressures across the RPM band, with the hydraulic design eliminating solid-lifter complexity while maintaining tight valve control. The XR286HR-10 designation reflects a duration and lift profile calibrated for big-block Mopar architecture, featuring roller-follower compatibility that reduces friction losses and extends lifter longevity compared to conventional flat-tappet designs. The robust 24.3-inch core length ensures proper valve overlap and scavenging characteristics essential for naturally aspirated big-displacement engines.

Mechanics rebuilding 440 or 454 big-block engines will appreciate the straightforward installation—the hydraulic lifter design eliminates shimming adjustments while the roller profile integrates seamlessly with stock or aftermarket rocker ratios. This cam excels in street machines and weekend warriors where torque delivery matters as much as top-end horsepower, and it pairs efficiently with factory-style intake manifolds on restorations or performance builds. Proper break-in procedure using COMP CAMS' recommended assembly lubricant is critical to ensure optimal lobe wear and longevity.
