Installed easily and improved performance as expected. Review: Best servo for the price! - Strong and fast! At an ok price as well. Comparable to the reefs 99 but at a better price. So far unbreakable. (I have done all the things that have broken others) It is slightly longer than stock, but the wires come out of the side, so it can work to replace the stock servo (on trx4m) . I would take a star off because desertcart had delivery problems, but I dont want that to reflect on Injora. Nothing but good products from them. ## Features - 【Brand Product】INJORA coreless metal gear high torque digital micro servo, high sensitivity, stable and low-noise. - 【Excellent Performance】 High precise metal gear, with better accuracy and longer service life. - 【Perfect Combination】This servo is equipped with metal mount and servo horn, replaces the original plastic accessories. - 【Application Scope】Water Resistant with O-ring seal, perfect for TRX4M Defender, Bronco, K10 High Trail, F150, TRX4MT 1/18 RC Crawler Upgrade. - 【Note】Not compatible with the original TRX4M servo mount and servo horn. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BTBR2PDC | | Age Range Description | Unisex Adult | | Best Sellers Rank | #31,787 in Toys & Games ( See Top 100 in Toys & Games ) #21 in RC Servos | | Brand Name | INJORA | | Color | Black | | Customer Reviews | 4.7 out of 5 stars 569 Reviews | | Educational Objective | Game, play | | Included Components | Servo, Servo Mount, Servo Horn | | Is Assembly Required | No | | Item Type Name | RC Servo | | Item Weight | 0.1 Pounds | | Manufacturer | INJORA | | Manufacturer Maximum Age (MONTHS) | 120 | | Manufacturer Part Number | INJS11-4MBK | | Material Type | Aluminum, Stainless Steel | | Model Number | INJS11-4MBK | | Number of Players | 1 | | Operation Mode | Automatic | | Power Source | battery | | Size | Small | | Subject Character | RC Servo | | Supported Battery Types | Battery required (6V-8.4V) | | Theme | RC | | Unit Count | 1.0 Count | ## Images ![Coreless High Torque Micro Servo with Mount and Servo Horn for TRX4M TRX4MT 1/18 RC Crawler Upgrade Parts(Black) - Image 1](https://m.media-amazon.com/images/I/61JZOKOQpJL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommend! *by K***B on April 3, 2026* Solid upgrade part. Installed easily and improved performance as expected. ### ⭐⭐⭐⭐⭐ Best servo for the price! *by J***N on April 16, 2026* Strong and fast! At an ok price as well. Comparable to the reefs 99 but at a better price. So far unbreakable. (I have done all the things that have broken others) It is slightly longer than stock, but the wires come out of the side, so it can work to replace the stock servo (on trx4m) . I would take a star off because amazon had delivery problems, but I dont want that to reflect on Injora. Nothing but good products from them. ### ⭐⭐⭐⭐⭐ Great upgrade at a good price. *by A***2 on June 25, 2024* Servo looks great, black with aluminum cuts. Fit perfectly with the Injora aluminum axles. Much better performance than stock servo in speed, power, and durability, and price. This set comes with the servo, mount, and servo arm, for the price of the OEM servo alone. Semi easy to install (there are no instructions) If you are using the Injora aluminum axels you will need the 2 micro grub screws and a .05 allen key to install, but set servo into the mount first then tighten the grub screws, but not too tight. Not sure how it fit stock plastic axels. ## Frequently Bought Together - INJORA Coreless High Torque Micro Servo with Mount and Servo Horn for TRX4M TRX4MT 1/18 RC Crawler Upgrade Parts(Black) - INJORA Brass & Aluminium 59mm Shocks- Long Threaded Shock Absorber Oil Damper for TRX4M TRX4MT 1/18 RC Crawler Upgrade - 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.in/products/520589596-coreless-high-torque-micro-servo-with-mount-and-servo-horn](https://www.desertcart.in/products/520589596-coreless-high-torque-micro-servo-with-mount-and-servo-horn) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-22*
