RC enthusiasts with Traxxas Hoss, Rustler, or Slash 4x4 models, listen up - this Extreme Heavy Duty rear shock tower (part number TRA9039T) is built to handle serious bashing and jumping! Now, super important note - this shock tower is specifically designed to be used WITH the optional Traxxas Heavy Duty Upgrade Kit (TRA9080), so it won't fit the factory suspension parts that come standard on your model. The bright orange color looks awesome and makes it easy to spot, but more importantly, the EHD construction is significantly stronger and more durable than stock components. When you're running upgraded power systems or just pushing your RC hard with big jumps and rough terrain, the stock parts can bend or break - this shock tower provides that extra strength and reliability you need. Installation is straightforward if you're familiar with RC maintenance, and it integrates perfectly with the rest of the heavy duty upgrade components. The design maintains proper geometry for your suspension while adding that crucial reinforcement at a key stress point. Whether you're into bashing, racing, or just want peace of mind that your RC can handle harder driving, this upgrade is totally worth it. Traxxas makes quality parts that fit perfectly and work exactly as intended, so you don't have to worry about compatibility issues or modification headaches. If you've already invested in the heavy duty upgrade kit or are planning to, this shock tower completes the package and ensures your rear suspension can take whatever punishment you dish out. Seriously, if you're tired of bending shock towers during aggressive runs, this EHD version will save you money and downtime in the long run!
