Stock HEAVY DUTY extra thick (1.15 to 1.2 ratio) for clone, gx, non hemi predator when running 22 pound and up springs with stock style rockers on a budget.

Some have asked about hardness and wear resistance, so I did an old school heat treat hardness check on them with a file and found them to be "file hard", this led me to ask my supplier about it and what I found was this. "The material of the rocker is: ST12, and they heat treated with a Carbonitriding heat treatment process. After that process, the surface hardness testing specs: are 85-91HR15N by Superficial Rockwell hardness". Meaning they will be resistant to wear

This is just the rocker arm, you will need to provide the stock stud, nut and adjuster

NOT LEGAL FOR AKRA OR OTHER SANCTION BODY RULES MOST LIKELY
