This is a optional JConcepts Chassis Over Tray, and is intended for use with the Traxxas Slash 4x4 short course truck. When racing on a loamy or top soil track surface the inside of the 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 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.

NOTE: Not compatible with LCG trucks.


  • Original JConcepts simple design and function
  • Durable clear polycarbonate material can be painted or wrapped
  • Plenty of clearance for various electrical and battery configurations

JConcepts Chassis Over Tray (Clear) (Slash 4x4)
I want to let everyone know that this over tray will not fit on your slash 4x4 without quite a bit of trimming. Which is perfectly fine as long as you expect to do a little mucking around. With that being said, this thing works great once you get it to fit right. I put duct tape flaps down along the sides so I could use velcro to attach it to the main chassis. I use my over tray in the snow and it keeps 99% of snow out. It makes clean up a whole lot easier and is also very convenient when running in loose gravel because it keeps debris out of that open spot in the driveline. I would recommend it, but know that you will have to do a little work to make it fit right.

Love this, one of my favorite mods. It does need to be trimmed, just like if you buy a clear body, super easy to do tho. I use 4 velcro squares on each corner and it stays in place for whatever I throw at it and still easy to pop off for battery change. Has places to cut vents into for cooling. I also added some window screen to cover the vents to maintain debris control. Got one for my 7 year old as well and he has no problem putting it on and off. A+

Wires on the chassis push the cover up on one side and since there is nothing that really holds it firmly in place it just pops up. Plus, I had to cut custom nothches out for my front sway bars.
