Traxxas Sealed Receiver Box Low-CG 4x4 Waterproof Protection TRX7424

This replacement part comes from Traxxas, the world's leading manufacturer of ready to run RC vehicles and components. The TRX7424 sealed receiver box is engineered with meticulous attention to detail and manufactured to the same exacting standards that have made Traxxas the preferred choice of professional racers, weekend bashers, and RC enthusiasts across the UK and globally. Installing this waterproof receiver box transforms your RC car into a more resilient machine capable of handling whatever terrain and weather conditions you throw at it.

Key Features

• Fully sealed receiver box design — The sealed construction completely encases your receiver to keep water, dust, dirt, and debris away from sensitive electronics, which is essential for maintaining signal integrity and radio reliability during wet weather operations or dusty track sessions.
• Low-CG chassis compatibility — This receiver box is specifically engineered to fit Traxxas low-CG 4x4 chassis platforms, ensuring perfect alignment and fitment without modification, and providing the correct geometry for optimal weight distribution and handling characteristics.
• Waterproof protection — The sealed design creates a waterproof barrier that keeps your receiver dry and functioning reliably, which extends component lifespan and prevents corrosion, oxidation, and electrical damage from moisture exposure.
• Included silicone seal and grease — Every box includes silicone seal material and protective grease to maintain the waterproof integrity of the enclosure, ensuring consistent protection throughout the lifetime of the component and making maintenance straightforward.
• Complete hardware package — The box arrives with all necessary mounting hardware pre-sorted: 2.5x12mm cap screws (2 pieces), 3x6mm cap screws (2 pieces), and 3x12mm button cap screws (2 pieces), eliminating the need to source fasteners separately and ensuring correct installation.
• Professional-grade construction — Built using Traxxas's proven manufacturing standards, this sealed receiver box provides durable, long-lasting protection that maintains its integrity through years of demanding RC driving, whether you're bashing at weekends or competing at track events.
• Foam pad inclusion — The box includes foam padding that cushions and isolates your receiver from vibration and impacts, reducing stress on internal components and connectors whilst keeping everything securely in place during aggressive driving.

Technical Performance

The Traxxas TRX7424 represents advanced engineering designed specifically for the demands of modern RC running. This sealed receiver box is manufactured from durable materials engineered to withstand the vibration, impacts, and environmental stresses inherent in RC driving. The sealed design incorporates precision-moulded construction that creates a waterproof chamber, protecting your receiver from water ingress whether you're fording through puddles, navigating wet grass, or running in light rain conditions. The included silicone seal material and protective grease work together to maintain a consistent waterproof barrier, whilst the foam padding absorbs vibration and impact forces that would otherwise be transmitted directly to your sensitive receiver electronics. The complete fastener package — comprising three different sizes of precision-engineered cap screws and button cap screws — ensures secure, vibration-resistant installation. This attention to detail in both design and included components reflects Traxxas's position as the leading manufacturer of high-performance RC vehicles and parts in the UK and internationally. The box's compact, streamlined design fits seamlessly into the low-CG chassis architecture without adding unnecessary bulk or weight, maintaining your vehicle's handling characteristics and performance envelope.

Frequently Asked Questions

• Is this sealed receiver box waterproof for river running and water crossings? — Yes, the TRX7424 is a fully sealed waterproof receiver box designed to keep your receiver electronics dry and functioning during water exposure. The sealed construction, silicone seal material, and protective grease work together to create a waterproof barrier that protects your receiver from water ingress. This makes it ideal for RC drivers who enjoy challenging terrain including water crossings, wet grass, and rainy conditions. However, for extreme water immersion, always exercise caution and check that all seals are properly maintained.
• Will this receiver box fit my standard Traxxas chassis vehicle? — No, the TRX7424 is specifically engineered for low-CG 4x4 chassis platforms and does not fit standard chassis designs. If you own a standard chassis Traxxas vehicle and wish to upgrade to low-CG geometry, you will need to perform a complete chassis conversion using Traxxas conversion kit 7421, which includes all necessary components alongside this sealed receiver box.
• What tools do I need to install this sealed receiver box? — You will need standard RC tools including a screwdriver set that fits the included cap screws and button cap screws. The fasteners provided are 2.5x12mm cap screws (2), 3x6mm cap screws (2), and 3x12mm button cap screws (2). All hardware is included in the package, so you don't need to source fasteners separately. We recommend applying the included protective grease to the silicone seal to maintain waterproof integrity.
• How do I maintain the waterproof integrity of this receiver box? — The TRX7424 includes silicone seal material and protective grease to maintain waterproof protection. After running in wet conditions, allow the box to dry completely before storing your vehicle. Periodically inspect the silicone seal for any signs of wear or damage, and reapply protective grease as needed to maintain the waterproof barrier. Replace the silicone seal if it becomes cracked, compressed, or degraded.
• Is this a genuine Traxxas part? — Yes, the TRX7424 is an official Traxxas OEM part manufactured to Traxxas's exacting quality standards. When you purchase from RC Model Shop, an authorised Traxxas retailer, you receive a genuine product with full manufacturer backing and warranty support.
• What is the difference between this sealed receiver box and a standard receiver box? — A sealed receiver box incorporates a waterproof design with silicone sealing materials and protective grease, creating a completely enclosed protective chamber around your receiver that shields it from water, dust, and debris. A standard receiver box offers basic protection but is not waterproof and cannot provide the same level of environmental protection. For RC drivers who operate in challenging outdoor conditions — including wet terrain, dusty tracks, or varying weather — a sealed receiver box like the TRX7424 is essential for maintaining receiver reliability and extending component lifespan.
• Can I use this box as an upgrade on my existing Traxxas low-CG 4x4 vehicle? — Yes, the TRX7424 is a direct replacement sealed receiver box for any Traxxas low-CG 4x4 platform vehicle. If your current vehicle uses an unsealed receiver box, upgrading to this TRX7424 sealed box will provide enhanced waterproof protection. Installation requires only basic RC tools and the fasteners are all included in the package.
