Product Details

The COMP Cams XFI XE-R Hydraulic Roller Camshaft line is built for GM LS Gen III/IV 3-bolt V8 engines. It is for builders who want a high-performance upgrade over a stock LS cam. The Xtreme Energy XE-R (XER) profiles are designed for aggressive power in LS1, LS6 and other LS-based engines, including larger-displacement builds. Different grinds in the line cover different engine sizes and power goals.

Key Features:

  • Hydraulic roller design: works with hydraulic roller lifters and avoids the upkeep of a solid-lifter setup.
  • Xtreme Energy XE-R lobe profiles: built to increase valve lift and duration for more top-end power.
  • Billet steel construction: a durable core for high-RPM use.
  • 3-bolt cam gear attachment: made for GM LS Gen III/IV engines.
  • Computer-controlled compatible: works with LS engine management systems.
  • COMP Cams engineering: made in the USA by a long-time leader in camshaft design.

Installation notes: An aggressive cam like this usually calls for matching valve springs, hydraulic roller lifters, and often a supporting tune. Check the specifications for each grind to match it to your engine and combination.

Emissions note: These camshafts are intended for race-only or off-road use on uncontrolled vehicles, not for emissions-controlled street vehicles.
