ARC 3.403 Billet Rod. Machined from 7075-T6 aluminum to the exacting specifications that you have come to expect from ARC Racing. Designed to work with the Honda GX160 UT2 piston in a GX200 block.
Rod bolt torque: 170 in / LBS lubricated
Installation Instructions:
  • To install your ARC rod you will need a 12 point 1/4" socket and a QUALITY inch pound torque wrench. You will need an outside micrometer, dial bore gauge or plasti gauge, and oil.
  • Measure the crank pin diameter with the outside mic, it should measure 1.180" +/-.0005". Measure in several spots to insure roundness. If out of round more than .0005" it probably should be replaced. The crank pin finish should be smooth to the touch.
  • When disassembling the rod notice on the side of the rod with the part number there are two dots next to the separation point of the beam and cap. These dots help to re-orientate the cap and beam when assembled. The side of the rod with the part number engraved will always face the side cover side.
  • Make sure the bearing and rod serrations are clean and install the bearings. Lubricate the rod bolt threads and hand tighten the bolts. Using the torque wrench tighten the bolts to 60" lbs. Alternate each side to increase the torque by 20" lbs at a time until you reach 150"lbs. Then loosen the bolts and repeat the torque process. this helps seat the rod bearing especially on a new rod. Measure the bore with your dial bore gauge opposite the parting lines. If using plasti gauge you will have to install the rod on the crank and use in accordance the plasti gauge instructions.
  • The rod bore should measure 1.183 +/.0005". With plasti gauge you are looking for about .003" clearance. From .0025-.0035" clearance is acceptable. Anything outside that dimension please call 800-521-3560 for recommendation.
  • Once clearance is set apply oil to rod, crank, and wrist pin and install this time torque to 170"lbs.
Improperly torquing rod bolts is one of the most common causes of rod failure.
Refer to instructions shipped with all rods and the video below for more detailed instructions.

Forged vs. Billet
If you are not familiar with the difference between billet and forged, we will explain how forging improves the strength of a connecting rod. A forged rod starts with an extruded metal or billet. The billet is placed into a die and hammered into a near-finished shape. The forging reshapes the grain structure of the billet from straight lines into the contour of the part. The reshaping of the grain structure improves the ductility, which is the component's ability to flex before breaking. The hammered part is also denser to make the overall rod stronger.

The Rods are fully CNC machines for a bright aluminum finish and accuracy.

Wrist Pin Journal fits: .709 Inch or 18mm (Clone/Predator)

Rod, Connecting, Billet, GX390, 4.510" (+.100")
GX390 billet rod with +.100 for custom applications and to get piston to zero deck height -includes rod bearings.
Machined from aircraft grade 7075 T-651 aluminum with advanced oiling features for superior lubrication to both the crankshaft and wrist pin. Made in the USA from 7075 Aluminum.
4.510" (+.100) long with scoop dipper. The extended .100" length from the standard 4.41" rods gives you the following benefits:
  1. Allows you to machine your stock piston down to a flat-top, which increases compression ratio (instead of milling the cylinder head) and lightens the piston.
  2. A lighter piston is more reliable and revs more easily.
  3. A flat-top piston provides better flame propagation, which equals a more efficient burn.
  4. A longer rod reduces piston speed and increases reliability.
  5. A billet rod is drastically stronger than the factory cast rod.
  6. A Babbitt bearing nearly eliminates the chances of crankshaft journal gall from lack of lubrication.

Also fits GX340s and most 13/15hp Chinese OHVs. On LCT/Duramax 16hp, the pin may need to be honed approximately .008.

**May require internal clearance.**
