When racing on a loamy or top soil track surface the inside of the Slash chassis can become loaded with dirt or debris which creates extra weight. With the JConcepts over-tray these worries are minimized with the simple and functional over-tray. Fitting nicely under the body; the JConcepts over-tray hugs the outside dimension of the Slash chassis protecting the inside from unwanted excess dirt and debris build-up during racing conditions. The over-tray fits snug around the entire chassis structure while being attached in the front with hook and loop tape (or Velcro if you prefer) for easy access. The over-tray is built with extra height and rake to provide extra room for various electrical and battery configurations The back-side of the lovers can be cut out for air to escape. Obviously holes can be added anywhere to release air but it adds to the stuffiness inside the over-tray. The over-trays are designed for the stock Traxxas power and electric or updated systems with compatible power.
