Traxxas Receiver Box Seal Kit TRX9625

Overview

The Traxxas Seal kit, receiver box (TRX9625) is an essential maintenance component for RC enthusiasts in the UK who own a Traxxas Sledge Belted 1/8 4WD Brushless Electric Monster Truck. Whether you're a seasoned RC car UK collector or someone who enjoys weekend bashing with high-performance brushless RC vehicles, keeping your receiver box properly sealed is crucial for protecting your electronics from moisture, dirt, and debris. This specialist seal kit allows you to refresh and restore the waterproofing of your sealed receiver box, ensuring your radio receiver and critical electrical components remain protected during intense off-road adventures.

Receiver boxes are subject to constant exposure to water, mud, dust, and other environmental contaminants when you're out running your ready to run RC monster truck. Over time, the original seals wear out, compromising the waterproof integrity of the enclosure. The Traxxas Seal kit provides everything you need to restore that protective seal to like-new condition, extending the operational life of your receiver box and protecting your expensive electronics investment. For anyone serious about maintaining their brushless RC truck in peak condition, this maintenance kit is a worthwhile investment that will save you money on replacement parts and downtime repairs.

Traxxas is renowned for producing high-quality RC vehicles and genuine spare parts that meet exacting standards. This seal kit is specifically engineered for the TRX3628 sealed receiver box, which comes standard on Traxxas Sledge models. If you've noticed water ingress, reduced radio signal quality, or visible wear on your receiver box seals, this is the perfect solution to restore full weatherproofing and reliability to your RC truck.

Key Features

• Complete seal replacement set — This kit includes all the components needed to fully reseal your receiver box in one purchase, eliminating the need to source multiple items separately and ensuring compatibility between all sealing elements.
• Includes new o-ring — The o-ring provides the primary seal between the receiver box lid and body, creating a watertight barrier that prevents liquid ingress into the sealed chamber where your receiver electronics are housed.
• Includes foam seal — The foam seal works in conjunction with the o-ring to provide additional weatherproofing and helps absorb any minor vibrations or impacts that could compromise the seal over time.
• Includes silicone grease — The silicone grease lubricates the o-ring and creates a superior water-resistant seal when applied correctly, ensuring maximum waterproof performance and making installation easier.
• Genuine Traxxas part — This is an authentic Traxxas manufactured component designed and tested to exacting standards, guaranteeing perfect fit and function with your Sledge receiver box.
• Easy installation — Refreshing your receiver box seals is a straightforward maintenance task that any RC enthusiast can perform at home with basic tools, extending the life of your vehicle without requiring professional service.

Technical Performance

The TRX9625 seal kit is engineered to restore the original waterproofing performance of the TRX3628 sealed receiver box used on Traxxas Sledge Belted 1/8 4WD Brushless Electric Monster Trucks. Sealed receiver boxes are a critical component of high-performance brushless RC vehicles, protecting the radio receiver from water, dust, and debris that would otherwise damage the delicate electronics. The combination of a precision-engineered o-ring and foam seal, along with the included silicone grease, creates a comprehensive waterproofing system that meets Traxxas engineering standards. When properly applied, these seals create a barrier that allows you to run your RC truck through water crossings, muddy terrain, and dusty conditions without fear of water damage to your receiver. The silicone grease is specifically formulated to remain effective across a wide temperature range, maintaining its waterproofing properties whether you're running your Sledge in summer heat or winter conditions. Regular maintenance and occasional resealing with kits like this one is part of responsible RC ownership and will significantly extend the operational life of your receiver box and connected electronics.

Frequently Asked Questions

• What is a sealed receiver box and why do I need to maintain it? — A sealed receiver box is a waterproof enclosure that houses your radio receiver and protects it from moisture, dirt, and debris. On high-performance brushless RC vehicles like the Traxxas Sledge, maintaining the integrity of these seals is essential because water ingress can cause receiver failure, loss of radio signal, or complete electrical damage. Over time, the original seals degrade through exposure to UV light, extreme temperatures, and constant flexing, which is why periodic resealing with a maintenance kit like the TRX9625 is recommended.
• How often should I reseal my receiver box? — The frequency depends on how intensively you use your RC truck and the conditions you run in. If you regularly run through water, mud, or dusty environments, you should inspect your seals every 5-10 hours of running time and reseal annually or whenever you notice water droplets inside the box. Casual users who primarily run on dry terrain may only need to reseal every 12-24 months.
• Is this seal kit suitable for my Traxxas RC car? — The TRX9625 is specifically designed for the TRX3628 sealed receiver box found on Traxxas Sledge Belted 1/8 4WD Brushless Electric Monster Trucks in all available colours (green, red, blue, and orange variants). If you own a different Traxxas model, you should verify compatibility before purchasing, as other receiver boxes may require different seals.
• Can a beginner install this seal kit themselves? — Yes, absolutely. Resealing a receiver box is one of the most beginner-friendly maintenance tasks in RC car ownership. The process typically involves removing the receiver box cover, removing the old seal components, applying silicone grease to the new o-ring, inserting the new foam seal, and carefully reinstalling the o-ring. Most users can complete this task in 15-30 minutes with just basic tools like a small screwdriver and possibly a silicone seal removal tool.
• What is silicone grease and why is it included? — Silicone grease is a waterproof lubricant that serves multiple purposes: it lubricates the o-ring so it sits properly in its groove, it fills microscopic imperfections in the seal surfaces to create a better waterproof barrier, and it prevents the o-ring from drying out and cracking. The silicone-based formula means it won't wash away in water like conventional grease would.
• How do I know if my receiver box seals need replacing? — Signs that your seals need attention include: visible water droplets or condensation inside the receiver box, decreased radio signal quality that seems unrelated to transmitter issues, a milky or cloudy appearance inside the box indicating moisture, or visible cracking or deterioration of the o-ring or foam seal when inspected.
