RC crawler fans, listen up! This INJORA axle set is about to take your TRX4M to the next level. We're talking about a complete front and rear axle package that gives you +4mm extension on each side - that's 8mm total width increase for way better stability on those tricky climbs. The front axle weighs in at 48g while the rear is 42g, both crafted from CNC machined aluminum with that slick black anodized finish that looks as good as it performs. Inside, you get hardened steel CVD shafts and durable 20CrMo alloy steel gears with the same 2:1 ratio as your stock setup (24/12 teeth configuration). The total length measures 122mm (about 4.80 inches) and they come pre-assembled to make installation a breeze. You also score 5mm brass wheel hexes (that's +1mm over stock) and all the necessary hardware. These bad guys are specifically designed for TRX4M models like the Defender, Bronco, K10 High Trail, and F150. But heads up - because these axle housings are extended, they won't play nice with your original TRX4M steering links and dogbone shafts. You'll need to plan your full upgrade accordingly. The precision machining means everything fits perfectly without slop or play, and the materials can handle the abuse of serious crawling. Whether you're tackling rocky terrain or just want that wider, more aggressive stance, these axles deliver both looks and performance. The extended design really does make a noticeable difference in side-hill stability and prevents tipping on extreme angles. Your crawler will feel more planted and confident on obstacles that used to be challenging. Plus, the quality construction means they'll last through countless trail runs and competitions. If you're serious about upgrading your TRX4M's performance, this axle set is definitely worth considering.
