This is the optional Pro-Line ProTrac Suspension Kit, and is intended for use with the Traxxas Slash short course truck. The ProTrac Suspension Kit features a race inspired design that uses 10mm wider suspension arms for the best combination of light weight and durability, and uses a dedicated -10mm Offset Split Six wheel to bring the track width back to stock specifications. Ultra durable rear hub carriers that are stronger than the stock parts, offer new camber and roll center positions for a greater level of adjustability. The shock towers provide correct shock progression and increased stability. The front and rear shock towers offer 3 camber locations, and two shock positions, as well as a high performance appearance.
