Product Details

The COMP Cams 54-446-11 XFI XE-R hydraulic roller camshaft is engineered specifically for GM LS Gen III and Gen IV engines, delivering improved performance across the RPM range. This camshaft features a 232/234 duration profile that provides excellent mid-range torque and top-end horsepower gains while maintaining good streetability and idle quality.

Key Features:

  • Hydraulic roller design for reduced friction and improved valvetrain stability
  • 232° intake / 234° exhaust duration at .050" lift provides aggressive performance
  • XE-R profile optimized for improved throttle response and power delivery
  • Compatible with factory fuel injection and computer controls
  • Designed for GM LS1, LS2, LS3, LS6, LQ4, LQ9, and other Gen III/IV LS engines
  • Requires upgraded valve springs and proper valvetrain components

This camshaft is ideal for street/strip applications where increased performance is desired without sacrificing driveability. The XFI XE-R grind provides a noticeable improvement in power over stock while still allowing the use of factory electronic fuel injection systems. Professional installation and proper valvetrain setup are recommended for optimal performance and reliability.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

great and reliable

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
