This is an essential upgrade for the 183XX rc trucks. The stock plastic gears don't last very long. However, you also need to add shims to the outdrives if you want the metal gears to last. If you have any left-to-right play in the differential, the gears will separate and strip. Find some 12mm x 10mm shims (0.1 to 0.2 mm thick) and put them between the outdrive bearings and the differential housing until all the slop is gone. And don't forget to grease the gears!

Excellent quality, assembled identically to the originals. Remember to remove the plastic end sheaths from the originals, swap the ball races, and then fit the plastic caps to the new metal set.

Parts arrive sooner that expected. Purchased as spares for when the original plastic parts wear out.

One of the parts that I HIGHLY recommend you upgrade if you purchase a HS 18311, 118312, or 18321. The plastic ones that comes with the RC wears out/broke in less than a week. Easy to upgrade and works perfectly.

Great upgrade. upgraded to metal ones as the old plastic ones got chewed up. the metal one can handle the power. Its smoother too ones you grease it.
