Just finished installing the Injora steel diffs and I am amazed at how much slop went out of the drivetrain. They fit perfectly in my truck. I'm running stainless Injora axles, replacement sealed bearings, and Treal brass diff covers. The mesh on the helical gears is perfect - super smooth on the set I received. Highly recommend. Ordering a second set now for my son's TRX4M. ## Frequently Bought Together - INJORA 24T/12T 6g Alloy Steel Helical Gear Set for 1/18 TRX4M Front Rear Axles(2PCS) - INJORA Steel Sealed Bearing Kit for TRX4M 1/18 RC Crawler Upgrade Parts, 22PCS - INJORA Drive Shaft Steel Black Front Rear Center Shaft with D Shaped Hole for TRX4M Defender Bronco 1/18 RC Crawler Upgrade, 22g/Set --- ## 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.tn/products/518386864-24t-12t-alloy-steel-helical-gear-set-for-1-18](https://www.desertcart.tn/products/518386864-24t-12t-alloy-steel-helical-gear-set-for-1-18) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-29*
