*This listing is for an Ultra Rare and long discontinued Vintage Genuine Original HPI Racing 75140 PRO4 Front One-Way 39T Differential Unit. Please DO NOT use our pictures for your own listings. Or we will have no choice but to report the listing to eBay for copyright infringement. Thank you for your cooperation in advance.

*This very unit is brand new and never used or opened within their separate packaging. The original retail HPI tab/stub is long gone but everything is present as you can see from the pictures. Nothing else is missing as far as I’m aware of. Everything is Made in JAPAN back in the days! Nothing but pure quality here folks!

*These factory spare replacement/optional parts for your 1/10 touring car are getting extremely rare so get it while it is available and don't miss out! Shop here and SAVE BIG! We DO NOT charge for unnecessary state tax (unless eBay enforced for certain states since 2019) and we are currently using the eBay International Standard Delivery method to avoid many delayed & lost packages for international shipments. This is also due to the fraudulent buyers out there as well. So make sure you thank those folks for it.

*Please visit our store for even more vintage genuine original HPI optional & spare replacement parts that you are not going to find anywhere else!
