Hydraulic Roller Master List
HIGH ENERGY AND MAGNUM HYDRAULIC ROLLERS - LOW & HIGH LIFT
The low lift profiles were designed for street and marine use. The low lift adds dependability and reliability for extended use applications.  The high lift versions of the hydraulic rollers are designed for all out applications where high lift is desired because of cylinder head or engine modifications. They function well for street, strip. These lobes run well in big cubic inch marine engines.

XTREME ENERGY HYDRAULIC ROLLERS
These designs share all of the characteristics of the flat tappet lobes but we have added the new technology of CRC (Constant Radius of Curvature) inverted radius of curvature ramp designs.  COMP Cams has enhanced this technique to ensure durability with these most aggressive hydraulic roller designs.  The high lift versions that have lobe numbers in the 3100's are more aggressive over the nose and will require more spring or less RPM. These lobes run well in street, strip and marine applications. With more agressive and faster ramps, they also provide good vacuum.

XTREME 4X4 HYDRAULIC ROLLERS
Due to the allowances of lower engine speed, these designs are slightly faster than the original Xtreme Energy Hydraulic Rollers.  Great low and midrange torque.  They are our most aggressive hydraulic roler lobes and run well in street, off road and four-wheeling.

XTREME ENERGY XFI HYDRAULIC ROLLERS
The Xtreme Energy XFI Series is designed for use with modern induction systems, heads, springs and rockers.  The XFI intake lobes have more lift than the base Xtreme series, and the XFI exhaust lobes have more area under the curve, for better exhaust flow, than the base exhaust series.  These are the first hydraulic flat tappet profiles designed for use with COMP Cams' Beehive Ovate valve springs such as the #26915, #26918 & #26120.  The combination of these profiles, the new springs, and our very stiff Pro Magnum rocker arms in higher ratios, makes for the most revolutionary improvement in hydraulic roller design to date by bringing the latest race winning technology to the street.

XTREME ENERGY XE-R FOR LS1
The XE-R designs are our most aggressive hydraulic roller ramps to date.  They are quicker off and on the seat than the original Xtreme Energy Series, yet they are still stable with rigid valve train and optimized spring selection.  These profiles provide even more area than the comparable Small Block Chevrolet designs that are often used by other companies to "grow" a more aggressive lobe for LS-1 applications.

CHEATER HR LIFT RULE COMPETITION HYDRAULIC ROLLERS
The Cheater HR lift rule profiles can be run with either hydraulic roller lifters or with solid roller lifters and tight (0.010" to 0.016") lash settings.  These are very popular in Mustang lift rule class racing. These lobes are very aggressive and are "race only" designed lobes.
