Description -
 
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/Duromax 16hp, the pin may need to be honed approximately .008.

*May require internal clearance.
