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
