About a week ago, I contacted Nate at Nasty performance and I sent my stock rocker arms out for the Harland sharp bearing rebuild, in order to avoid any headaches of the oem rockers failing and needle bearing goign everywhere. This cost me $260 and i just got them back today, and I am very pleased.
The first picture is how they came, better than new. However, Harland Sharp did not have to clean these, they were brand new when i sent them, lol so i assume if you send used ones they'll look a few shades darker and not look this perfect.
The second and third pics are a side by side comparison of a OEM used one and a HS rebuilt one. The oem ones seem to have about a 45 degree range of motion only, where as the HS rebuilds ahve a full 360 degrees and thicker diameter shaft in addition to the snap rings which secures it all.
