Product Details

The COMP Cams Xtreme Energy CL12-444-8 is a complete hydraulic roller camshaft and lifter kit designed for Chevrolet small block engines seeking aggressive performance gains. This kit features a 248/254 duration split that delivers excellent mid-range to top-end power, making it ideal for street/strip applications and performance street machines.

Camshaft Specifications:

  • Advertised Duration: 268°/280° intake/exhaust
  • Duration at .050": 248°/254° intake/exhaust
  • Valve Lift: .533"/.540" intake/exhaust (with 1.5 rocker ratio)
  • LSA (Lobe Separation Angle): 110°
  • Hydraulic roller design for reduced friction and increased durability
  • Recommended RPM range: 1,500-6,000 RPM

Complete Kit Includes:

  • Xtreme Energy hydraulic roller camshaft
  • Hydraulic roller lifters (16)
  • Assembly lube for proper break-in

This cam profile is engineered for engines with upgraded valve springs, intake systems, and headers. It provides strong acceleration and aggressive sound while maintaining reasonable idle quality. The hydraulic roller design eliminates the need for a break-in procedure and provides superior wear characteristics compared to flat tappet cams. Ideal for engines with compression ratios of 9.5:1 or higher and converter stall speeds of 2,400-2,800 RPM for automatic transmissions.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Good customer service.Very friendly persons in service dept as well. Will shop here again.

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. ;-)

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!
