NOTE: This product has now been replaced with our injection-molded Low CG Battery Tray Combo for TRX-4:




These are in-house printed versions of our popular Low CG Battery Tray for the Traxxas TRX-4. Using 3D imaging technology, we've taken full advantage of nearly every available cubic millimeter to lower the battery tray floor, lowering the center of gravity and making more room for more packs of different shapes and sizes. The in-house versions are printed using carbon fiber-strengthened nylon filament and include slots for standard velcro battery straps so that you can secure your pack. Our battery tray allows packs up to 53mm between the side walls and up to 140mm long from the lower front wall when used with our companion rear chassis brace. That's long enough for most 2S hard packs, as well as many 5000 mAh 2S and 3S soft packs.

    Low CG Battery Tray for TRX-4

    Posted by Brian Brigg on Sep 5th 2018

    I did some homework on the low CG battery tray before buying so there were no surprises. Well, actually one surprise. My order arrived to Indonesia in far less time than I expected getting here in the sort of time that normally requires priority post.

    Installation was a breeze with only a little extra pressure needed to start the screws threading in their holes. The excellent design meant that everything lined up very well. The tray allows the battery to sit much lower than the stock tray which has benefits in the way the vehicle handles, especially during side hilling.

    One thing that buyers must note is that the battery does sit a little farther back than stock as well. I had installed some brass knuckle weights at about 112 grams each and this had made the rig front heavy so the rearward shift of the battery helped counter that.
