Made from black brass, each piece weighs 4 grams. The pair replaces plastic originals to add low-weight forward, improving stability on steep climbs and reducing rollover. Precision CNC machined with the INJORA logo.\u003c\/p\u003e\u003ch2\u003eWhy switch to brass caster blocks and C-hubs?\u003c\/h2\u003e\u003cp\u003eThe factory plastic parts on the TRX4M front axle are lightweight but do little to improve weight distribution. Adding brass caster blocks and C-hubs puts extra mass where it counts—right at the front wheels. This lowers the center of gravity and increases front-end traction. The result is better anti-rollover stability and more reliable climbing performance on uneven terrain. Each block weighs 4 grams, so the total added weight is 8 grams across the front axle. The black brass material is durable and wear-resistant, outlasting standard plastics. This upgrade is a common first step for crawler enthusiasts looking to improve balance without changing suspension geometry.\u003c\/p\u003e\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eBlack brass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight per piece\u003c\/td\u003e\n\u003ctd\u003e4 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e2 pieces (pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eTRX4M Defender, Bronco, K10 High Trail, F150 (1\/18 scale)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMachining\u003c\/td\u003e\n\u003ctd\u003eHigh precision CNC, etched INJORA logo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlacement\u003c\/td\u003e\n\u003ctd\u003eFront axle only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat's included and installation notes\u003c\/h2\u003e\u003cp\u003eThe package contains two black brass caster blocks\/C-hubs. They are direct replacements for the plastic parts on the TRX4M front axle. No additional parts are required, but you will need basic tools for disassembly. The CNC machining ensures a precise fit straight out of the box. The etched INJORA logo adds a clean, upgraded look that matches other INJORA components. These parts are designed to work with the stock screws and bearings, so installation is straightforward.\u003c\/p\u003e\u003ch2\u003eCompatibility with TRX4M models\u003c\/h2\u003e\u003cp\u003eThese parts are specifically engineered for the Traxxas TRX4M platform. They fit the Defender, Bronco, K10 High Trail, and F150 body styles. All are 1\/18 scale RC crawlers. The upgrade is intended for the front axle only; rear axle parts are not included. If you own a different TRX4M variant not listed, the front axle design is identical across the line, so these should fit as well.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWill these caster blocks work on the rear axle?\u003c\/h3\u003e\u003cp\u003eNo, these are for the front axle only. The rear axle uses different C-hubs and caster blocks. Use a rear-specific set for balanced weight distribution.\u003c\/p\u003e\u003ch3\u003eDo I need to buy any additional hardware?\u003c\/h3\u003e\u003cp\u003eNo. The blocks replace existing plastic parts. Reuse the original screws and bearings. All necessary hardware is already on your truck.\u003c\/p\u003e\u003ch3\u003eHow much weight do they add?\u003c\/h3\u003e\u003cp\u003eEach piece weighs 4 grams, so the pair adds 8 grams total to the front axle. This is enough to improve stability without overloading the suspension.\u003c\/p\u003e\u003ch3\u003eAre they made of solid brass?\u003c\/h3\u003e\u003cp\u003eYes, they are machined from solid black brass. The material is denser than plastic, providing the weight increase needed for better crawling performance. The black finish resists wear and corrosion.\u003c\/p\u003e","brand":"INJORA","offers":[{"title":"Default Title","offer_id":58076010086703,"sku":null,"price":25.72,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/injora-black-brass-caster-blocks-c-hubs-4g-front-axle-upgrade-for-trx4m-118-rc-crawler-1.jpg?v=1781530206","url":"https:\/\/toysforkid.co.uk\/products\/injora-black-brass-caster-blocks-c-hubs-4g-front-axle-upgrade-for-trx4m-1-18-rc-crawler","provider":"Toys For Kid","version":"1.0","type":"link"}
