Blomiky 2 Pack New Version 9125 25-ZJ06 Differential Gear Spare Parts for 1/10 Scale Blomiky 9125 RC Car 9125 Differential 2

If you're looking to purchase this product, you probably have worn out a differential or two on your 9125 truck. I've come to accept the fact that these plastic differentials simply need to be replaced quite frequently even if you maintain/grease them regularly. Therefore, I won't knock down the rating because these parts do meet my so-so expectation.The seller Blomiky, however, is excellent. One of the differentials I received worn out on the first battery run. I contacted Blomiky and they replied within 24 hours and sent me a replacement. Their customer service earned my 5-star rating.

Had purchased similar “upgrade” that wasn’t much of an upgrade because it broke rather quickly. This upgrade was exactly that, AN UPGRADE! WOW!

It is a nice piece but is not the same as mine which is listed as the same part number. This one has larger teeth on the ring gear creating interference in the very tight plastic gear case. I machined the teeth down slightly and it fit perfectly. So it is usable but will require some work

I have a Soyee 1:10 truck who's rear diff seized up. Purchased this pack and it seemed to be a perfect fit. However, as others have mentioned, there's a terrible grinding noise after it's installed. The teeth seem ever so slightly different. I'm uncertain if it's from the wear or what, but it does not work in my truck.

Upgrade differential way better then stock, trucks been sitting for awhile glad to bring it back to life!

The part I do not like is how expensive these pieces are. This was the best value I could find so I had to buy it. However the product is pretty goood. So far they haven't broke and they are working fine.

By far the best diff for the 9125 rc truck on the market runing 4s in my truck an all other diffs besides these will diff will fail at 4s power 110 brraap..

Took about an hour to replace thanks to an youtube video. car is running great again.
