Product Details

The COMP Cams CL54-446-11 XFI XE-R camshaft and lifter kit delivers enhanced performance for GM LS Gen III/IV engines. This complete kit features a hydraulic roller camshaft with 232° intake and 234° exhaust duration, designed to provide excellent mid-range to upper RPM power gains while maintaining acceptable idle quality.

Key Features:

  • Hydraulic roller camshaft with 232°/234° advertised duration
  • Engineered specifically for GM LS Gen III/IV engines
  • XFI XE-R profile optimized for performance street and mild competition applications
  • Includes premium hydraulic roller lifters for reliable valve train operation
  • Complete kit with assembly lube, installation instructions, and COMP Cams decals
  • Improved throttle response and horsepower over stock camshafts

This camshaft kit is ideal for enthusiasts seeking a noticeable performance upgrade with a slightly aggressive idle note. The hydraulic roller design provides durability and reduced friction compared to flat tappet camshafts, making it an excellent choice for street performance builds. Professional installation and proper valve spring verification are recommended for optimal results.

Order # 26695 I ordered an EGT and a gauge pod. It showed up at my house 4 days later exactly as I had ordered it. The Prices are unbeatable!

Very good price, fast shipping, A+

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. ;-)

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Great prices and super fast shipping. Good job.

The correct product that I ordered, and easy to find through there web site.thanks

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
