550 Full Set Motor Gear Box, Middle, Small Gear - Kids Ride On Car Parts & Accessories

The product is as shown and easy to install.

Had to modify the large gear as the inside diameter was too small. Used a rotary tool and fine sandpaper to make it work. I bought 3 sets and all were same. Also the lip on bottom of large motor was too short, so had to add 2 machine bushings under each one to keep gear from rubbing on housing. Would suggest a different brand but they are all probably made in the same factory and was the reason I made them work instead of returning. These were used on a Sopbost brand 12v utv with 550 motors.

This was the only place I could find with a 550 10 Teeth / 54 Teeth 4.5 cm gear. Most other gear sets have 11 or more teeth. My son has a 4WD ride on jeep with gears like these, so it was great to find this. If they sold the small gear in bulk, I would buy it. So far, works great!

Worked for my application. The only difference, the middle gear had plastic teeth compared to metal teeth on the original.

Large gear did not fit over shaft

Had to replace stripped gears on my sons ride on and these were a perfect fit and easy to do. Simply take the gear box apart, take old gears out and place these back in. Put it back together and very easy to do and holding up good so far

Was able to replace broken gears with this

The largest gear did not fit the pin it was supposed to slide over. Thankfully the gear I needed was the opposite side one and the 2 that did fit worked with the old large gear. The hole was just not large enough.
