1.5 Ratio Aluminum Roller Rocker Arms

The Harland Sharp SHPS70015K is a heavy-duty rocker arm and shaft kit, precision-engineered for Mopar B and RB-Series engines. This kit features a 1.5 ratio rocker arm with a roller tip designed to minimize friction and wear. Constructed from durable aluminum and finished with an orange anodization for corrosion resistance and aesthetics, these rockers are built to withstand demanding performance applications. It is noted that for optimal fitment with Trickflow and Edelbrock heads, part number S70015KE may be a better option, while the S70015K set fits factory iron heads best. Installation involves bringing each piston to Top Dead Center and tightening rockers to the specified torque. Proper geometry is achieved when the rocker is at a 90-degree angle to the stud at the midpoint of cam lobe lift, ensuring the roller tip stays centered on the valve stem.
