DLC coated rocker spindle set to reduce friction & eliminate wear

The diamond like coating eliminates wear and reduces friction for a cooler more efficient motor. These spindles are drilled through so you can eliminate one oil line if you want because the intake spindles transfer oil from one side to the other. You must use a 1/2″ dia 320 grit flex hone such as “BRUSH RESEARCH BC1232″ (approx $20) to clean any burrs from the rocker ID before installation. Internal threads are 5/16” US fine. A Brit puller will thread in a short way or you can use a US bolt/nut/washer and short tube. (see flex hone and used DLC coated rocker spindle).
