This product is a pair of tunnel extensions (left and right) designed to reinforce and protect the chassis tunnel area of your RC vehicle. They help prevent debris intrusion and wear while maintaining proper structural alignment under heavy loads. The durable construction is built to withstand impacts and repeated use during trail or off-road driving. They are compatible with select Traxxas models that use tunnel extension parts. Ideal for maintenance or repairs, they support long-term chassis durability and performance.
