Product Details

The COMP Cams Xtreme Energy 212/218 hydraulic roller camshaft is engineered to deliver increased performance without compromising driveability or comfort. This camshaft features a quicker valve opening profile that provides enhanced throttle responsiveness and generates more area under the lift curve compared to traditional grinds.

Key Features:

  • 212°/218° advertised duration for excellent mid-range power
  • Hydraulic roller design for reduced friction and improved valve control
  • Optimized lift profile delivers gains in both torque and horsepower
  • Maintains adequate vacuum for power brakes and vacuum-dependent accessories
  • Designed specifically for Chevrolet Small Block engines
  • Compatible with carbureted applications

This camshaft offers the best performance when paired with aftermarket intake manifolds, lower gear ratios, headers, and free-flowing exhaust systems. The Xtreme Energy grind family is ideal for enthusiasts seeking a noticeable performance upgrade while maintaining street-friendly characteristics and drivability for daily use.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
