  • Duration @ .050": 224°/230° (Intake/Exhaust)
  • Valve Lift: .477"/.480" (Intake/Exhaust) with 1.6:1 rocker ratio
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,500 RPM
  • Recommended Valve Spring: COMP Cams #981-16 or equivalent

Key Features:

  • Xtreme Energy lobe profiles for maximum performance per duration
  • Hydraulic flat tappet design for quiet operation and easy maintenance
  • Aggressive idle with strong mid-range and top-end power

Good fast shipping. Easy ordering.

Thanks for working with Amazon

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

Wow Super fast shipping, right product, no hassle no fuss. just how i like it. good job autoplicity keep it up.
