92mm Flat Piston & 4.51" Billet Rod Combo

Do you have a GX390/420/440 engine and want to beef it up, get alittle more performance, and stay on a budget? This is the rod/piston combo for you!

This is the only billet connecting rod available that will fit a GX390/GX420/GX440 engine with ZERO block & balance shaft clearancing required. If you use one of our performance camshafts, it will clear that too! No need to whip out the grinder!

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 & revs easier.
  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 babbit bearing nearly eliminates the chances of crankshaft journal gall from lack of lubrication.

Rod Bearings included. Made in the USA from 7075 Aluminum

This is the OEM Flat-Top Piston in our 460cc engines equipped with the 4.51" Connecting Rod.

92mm Diameter

Piston Rings, Wrist Pin & Locks Included

Will also fit 440cc engines with a 4.51" Connecting Rod. GX390s & 420s will need to be bored out!
