Product Details

The COMP Cams FSL (Fuel Saver Lobe) 646-201-13 hydraulic roller camshaft is engineered specifically for GM Gen III/IV LS engines with three-bolt and Gen IV single-bolt cam retention systems. This drop-in performance upgrade delivers impressive power gains while maintaining emissions compliance and drivability.

Key Specifications:

  • Advertised Duration: 212°/224° intake/exhaust
  • Duration at .050": 210°/222° intake/exhaust
  • Hydraulic roller design for reduced friction and improved efficiency
  • Compatible with LS2, LS3, and other Gen IV single-bolt cam applications
  • Works with factory valve springs—no spring upgrade required

Performance Benefits:

  • 30 to 47 horsepower increase in peak power over stock camshaft
  • Improved throttle response and mid-range torque
  • Enhanced fuel efficiency through optimized lobe profiles
  • Emissions compliant—maintains catalyst and oxygen sensor function
  • No tuning required for installation in most applications

The FSL camshaft technology uses specially designed lobe profiles that maximize cylinder filling and combustion efficiency without aggressive valve timing that would compromise emissions or require extensive modifications. This makes it an ideal upgrade for street-driven vehicles, daily drivers, and late-model GM performance applications where emissions compliance is required. The hydraulic roller design provides quiet operation and long service life while delivering measurable performance improvements throughout the RPM range.

so far so good. Hoping the "fast ship Times" is a fact.

Gud service& price

First order, we’ll see how you do from here

The only flaw was that the search engine didn't find my tool. Had to look it up on Google and type in the part number. But still, fast and easy.

Excellent product with fast shipping!

Found the items needed with ease in the website and delivery was shorter than expected.
