But, Injora customer service is top notch. *by on Reviewed in the United States 16 July 2024* The shafts look great and fit perfectly. The issue is that the pins that holds the universal joint together slids out of the shafts. I am able to slide them back in, if I catch it in time. But they will be useless when one falls out and I can't find it.Injora makes great parts, but these are not up to their standards. I only ran 2 battery packs on them. I do have the Meus two speed transmission, but it's usually in low gear crawling. They should not be failing so soon.Injora customer service did respond to me, and send out a different set.I would recommend a different set of dive shafts. ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in Australia 22 August 2025* Fit my bronco trx4m perfectly ### ⭐⭐⭐⭐⭐ Injora come sempre top *by on Reviewed in Italy 27 May 2025* Ottimi upgrade di casa Injora, perfezione e qualità super. Piccoli alberi di trasmissione fatti benissimo e con precisione veramente alta. Nessun problema per il montaggio, molto veloce e facile da montare sul proprio modello. Consiglio sia upgrade che il venditore professionale e molto veloce nella spedizione.
