Product Details

The COMP Cams XFI RPM 54-412-11 hydraulic roller camshaft is engineered specifically for GM LS Gen III and Gen IV engines, delivering a performance-oriented profile that balances streetability with power gains. This camshaft features a 212/218 duration split at 0.050" lift, designed to optimize torque delivery and throttle response while maintaining smooth idle characteristics suitable for street-driven vehicles.

Key Specifications:

  • Duration at 0.050": 212° intake / 218° exhaust
  • Hydraulic roller design for reduced friction and improved durability
  • Optimized lobe profiles for GM LS Gen III/IV platforms (4.8L, 5.3L, 5.7L, 6.0L, 6.2L)
  • Improved mid-range torque and horsepower over stock camshafts
  • Compatible with factory fuel injection and engine management systems
  • Requires aftermarket valve springs and proper installation components

Performance Benefits:

  • Enhanced throttle response and acceleration
  • Broader powerband compared to factory camshaft
  • Maintains reasonable idle quality for daily driving
  • Hydraulic roller technology eliminates need for periodic valve adjustments

This XFI RPM series camshaft is ideal for street performance builds, mild towing applications, and weekend cruisers looking to unlock additional power from their LS engine without sacrificing driveability. Professional installation is recommended, along with proper valve spring upgrades, pushrods, and break-in procedures per COMP Cams specifications.

Great deal on my purchase. Tracking # given once order shipped 2 businesss days later. Good merchant.

Bought Motive Brake Bleeding Kit (international) . Best Pricing all around.<br>Ordered on Tuesday , received via UPS Ground (cheap shipping) on Thursday Noon.<br>Excellent Packing.<br>Super Fast Shipping.<br>Very Statisfied with my on-line order.<br>Highly Recommended.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)
