NR Racing Aluminum Full Roller Rockers for the Hemi Head | 1.2 or 1.3 Ratio
These rockers are crafted using aircraft-grade billet aluminum and feature replaceable steel roller tips. New steel shafts and roller bearings included.
- Dyno-tested to 10,000rpm and proven to increase horsepower
- Due to canted valve arrangement, Hemis may have valve-to-piston clearance issue with high-lift cam, especially with the 1.3 ratio.
- These rocker arms require shorter pushrods (typically 5.260 or 5.340, depending on cam and head milling).
*Note:Â These are designed to work with standard length or +.070" valves. They are not recommended for the +.230" valves. May require valve cover spacer or minor grinding on valve cover grinder for clearance.
