Product Description
Traxxas 82216-4 TRX-4 Crawler Kit, Clipless (TRA82216-4)
The TRX-4® 1/10 Scale Trail Rock Crawler Assembly Kit offers an exciting hands-on experience, combining the thrill of off-road performance with the satisfaction of assembling your vehicle. Known for its rugged durability and innovative design, the TRX-4 set the standard for off-road versatility, and this kit version includes the same advanced features as the ready-to-run (RTR) model. Enthusiasts can build key components like portal axles, a high/low range transmission, and remotely locking differentials, gaining a deeper understanding of the vehicle’s mechanics. The kit is well-organized, with all parts neatly packed in labeled bags, including waterproof electronics and pre-assembled shocks and suspension links for convenience. A fully illustrated, color manual ensures a smooth and enjoyable building process, making this kit just as fun to construct as it is to tackle rough terrain.
