Product Details

The COMP Cams 146-462-11 is a high-performance LSR (Low Shock Revolution) hydraulic roller camshaft engineered specifically for GM Gen IV LS engines without Variable Valve Timing (VVT) or Active Fuel Management (AFM). This camshaft features aggressive 243/259 duration specs designed to deliver substantial power gains in the mid-to-upper RPM range while maintaining excellent street manners.

Key Specifications:

  • Advertised Duration: 243°/259° (Intake/Exhaust)
  • Hydraulic roller design for reduced friction and wear
  • LSR profile optimized for low shock loading and extended valvetrain life
  • Compatible with GM Gen IV LS engines (LS2, LS3, L76, L92, L99) without VVT or AFM
  • Ideal for street/strip performance builds and mild to moderate forced induction applications

Performance Benefits:

  • Increased horsepower and torque throughout the powerband
  • Improved throttle response and engine efficiency
  • Aggressive idle quality with performance sound
  • Maintains good low-end torque while delivering strong top-end power

This camshaft requires compatible hydraulic roller lifters, performance valve springs, and proper ECU tuning for optimal performance. COMP Cams precision manufacturing ensures exact lobe profiles and consistent quality for reliable operation in demanding performance applications.

They had the lowest price and great communication. Will order from them again thanks

For as cheap as what I paid for my product I will admit I was scared!!! Got what I asked for in perfect condition, came fast and wonder where have you been all my shopping life? Thanx for such a great deal and fast shipping!!!

Incredible prices! I purchased a name brand leveling kit for 40% less than any one else is selling them for. Item shipped out within 2 days. Shipping cost is reasonable, and if you leave a review here after your purchase, they'll credit you back $5! BEST DEAL GOING!

this was a very easy and user friendly site to use.

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Good

best price, cheap shipping, easy to order, thank you Order Number: 4829<br>
