Overview
The Traxxas Shock tower, rear (left & right halves) TRX7838 is an essential replacement chassis spare part designed specifically for Traxxas XRT and Funco Motorsports Pro Scale models. Whether you're an experienced RC enthusiast running a high-performance 8S brushless RC vehicle or a dedicated weekend basher pushing your Traxxas to its limits, this genuine OEM component ensures your rear suspension geometry remains perfectly aligned and structurally sound. The rear shock tower is a critical structural element that maintains the correct mounting angle and spacing for your rear shocks, directly affecting suspension performance, handling characteristics and overall durability of your RC car.

Technical Performance
The rear shock tower is a fundamental structural chassis component that plays a crucial role in the suspension dynamics of your Traxxas XRT or Funco Motorsports Pro Scale 8S RC vehicle. As a mounting bracket for the rear shock absorbers, this component must maintain precise alignment to ensure consistent suspension travel, proper anti-roll characteristics and predictable handling across all driving conditions. The shock tower's geometry directly influences how effectively your suspension compresses and extends during acceleration, braking and cornering, which in turn affects traction, stability and overall vehicle control. For 8S LiPo-powered vehicles like the XRT Ultimate and XRT VXL-8S that deliver significant power and speed, a properly mounted rear shock system with correct geometry is essential for maintaining grip and preventing suspension binding. The engineering tolerances required for shock tower manufacturing are exacting, which is why genuine Traxxas parts are specifically designed and tested to work in perfect harmony with the rest of your vehicle's suspension system. Whether you're running your vehicle on rocky terrain, sand, dirt tracks or tarmac, this component must absorb impacts whilst maintaining the precise suspension angles that keep your tyres planted and your handling predictable. The left and right halves work together to create a symmetrical mounting platform that distributes suspension loads evenly across the chassis.

Frequently Asked Questions
- Which Traxxas models does the TRX7838 rear shock tower fit? — This rear shock tower is compatible with the Traxxas XRT Ultimate in Blue X and Green X variants, the Traxxas XRT VXL-8S in Green, Black, Blue and Orange variants, and the Traxxas Funco Motorsports Pro Scale 8S 2WD Electric Sand Car in Red, Blue, Orange and Green models. If you're unsure which variant you own, check your vehicle's model number or contact our team at RC Model Shop for confirmation.
- Is the TRX7838 a genuine Traxxas part? — Yes, absolutely. The TRX7838 is an authentic original equipment manufacturer (OEM) component produced by Traxxas to their exact specifications. When you purchase this part, you're getting the same quality and durability as the shock tower fitted to your vehicle from the factory.
- Do I need any special tools to install this rear shock tower? — The rear shock tower is designed as a direct bolt-on replacement part that requires only basic RC tools such as hex wrenches and screwdrivers. No modifications, drilling or special equipment is necessary—simply remove the damaged tower and bolt on the replacement using the existing mounting points on your chassis.
- What is the difference between replacing the shock tower versus repairing the existing one? — Once a shock tower has been cracked, bent or broken, structural integrity is compromised even if you attempt to glue or tape the damage. This affects suspension geometry and can lead to further damage to suspension components and unpredictable handling. Replacing it with a genuine Traxxas part restores your vehicle to factory specification and ensures long-term reliability.
- How often will I need to replace my rear shock tower? — Under normal driving conditions, the shock tower should last for years without replacement. However, high-impact crashes, rolling over obstacles, or significant collisions can damage the tower. Regular inspection of your chassis and suspension components helps you spot damage early before it affects performance.
- Can I use this shock tower on other Traxxas models? — No, this rear shock tower is specifically engineered for XRT and Funco Motorsports Pro Scale models. Using it on other Traxxas vehicles would result in incorrect suspension geometry and poor handling. Always use the correct part number specified for your vehicle model.
