## Description

INJORA Center Drive Shafts Stainless Steel Upgrade Part 2pcs for 1/18 TRX4M Defender Bronco RC Crawler Car(4M-18) : desertcart.co.uk: Toys & Games

Review: 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.
Review: Fit my bronco trx4m perfectly

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. Ottima esperienza 👍🏻
