Important installation instructions

  1. Disassemble and clean the rods (including bolt and beam threads) to remove rust preventative.
  2. Apply ARP Molylube to the threads and under the head of each bolt.
  3. Assamble the rod to the piston. The rod bearing notches must show to the intake of the engine, due to rotation direction of the crankshaft!
  4. Install rods by bringing cap and beam into alignment. Tap into place before installing bolts (DO NOT USE BOLTS TO PULL CAPS INTO POSITION) Each rod is numbered and MUST be assembled with the same number on cap and beam.
