Same as chrome ones.** A: Yes they the same, I have both sets so, I can confirm that they're the same **Q: Whould these fit fms fcx or furitek caymen? Thanks** A: They are for 1:18 scale crawlers, but they're only a few bucks, so try em out. You could probably cross reference sizes though to find out for sure. I know the hole to attach the shaft is a d-shaped hole. **Q: Any idea if these will work with the K10 High Trail?** A: I use them on my K10 Monster Truck build with 59mm INJORA shocks. It's at their limit, but functional. I think INJORA just came out with a stainless steel version, specifically for the K10, on their website. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very happy would recommend *by N***E on 8 July 2026* Great upgrade for the trx4m ### ⭐⭐⭐⭐⭐ . *by G***. on 16 July 2025* Another great product from injora. ### ⭐⭐⭐⭐⭐ Essential upgrade drive shaft for trx4m defender *by T***M on 16 January 2026* This item is brilliant easy to fit and good quality for the money ## Frequently Bought Together - INJORA Drive Shaft Steel Black Front Rear Center Shaft with D Shaped Hole for TRX4M Defender Bronco 1/18 RC Crawler Upgrade, 22g/Set - INJORA High Clearance Chassis Links Set Brass Black Coating Link for 1/18 TRX4M Defender Bronco Upgrade Parts RC Crawler, 48g - INJORA Brass & Aluminium 59mm Shocks- Long Threaded Shock Absorber Oil Damper for TRX4M TRX4MT 1/18 RC Crawler Upgrade --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/534301205-injora-steel-d-shaped-hole-drive-shaft-for-1-18](https://www.desertcart.jp/products/534301205-injora-steel-d-shaped-hole-drive-shaft-for-1-18) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-04*
