BowHouse RC Molded Low CG Battery Tray for Traxxas TRX-4
About this part
The BowHouse RC TRX-4 Molded Low CG Battery Tray is an injection molded option that allows you to take advantage of lower battery placement by holding the battery lower in the frame for the ultimate in low CG performance. The tray was designed using 3D imaging technology to take 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 battery options!
The tray is molded from a durable nylon compound and features a matte finish with polished BowHouse logo in the center that blends in with the stock parts perfectly. Plus, the package now includes the XL rear chassis brace! Previously, this was an accessory that had to be purchased separately - so now you can make room for stick packs up to 158mm long and hang them lower in the frame. If your goal is to maximize the performance of your TRX-4, without impacting the scale look of the truck, this battery tray is a must have upgrade!
NOTE: 200mm battery strap is recommended.

Good little product. It definitely helps with keeping the CG lower on the TRX-4. Only gave 4 stars because it doesn't come with a velcro strap. It's not mentioned in the description but the max width the battery can be is 53mm (thank you to AMain customer service to going to the warehouse to measure).
This is a nice product, yes it doesn't come with a strap, but it works well. I was able to slide the u shaped bracket forward enough to get an aluminium chassis crossmember back in to give better chassis support, I also added a second aluminium chassis crossmember between the shock mount supports. it actually fit perfect and I used 2 of the unused shock mount positions for mounting. It has stiffened up the whole design. I can run fast with a lot less roll in the turns. and with the lower cg, it also helps the turns get faster. I put this in the TRX-4 Blazer. I did change the esc and motor to the Hobby Wing Xerun Axe brushless system for crawlers,(Axe550-2700KV).
Great addition to my son's TRX4 Sport, but I need to trip the back of the battery tray to avoid rear axle upper links.
Fit in my sport high trail perfectly. It makes a difference running larger 3s packs!
Ontop of this being the lowest battery tray for the TRX4, you can fit the Killerbody LC70 TRX-4 body with this! the full sized bateries like the 7600Mah fits perfectly under the bed
Reviewers generally agree the BowHouse molded low-CG battery tray lowers the centre of gravity on the TRX-4 and is well made with a good fit and finish. Several note it ships without a velcro strap, and some say there are no installation instructions. Battery fit is the main point of disagreement: some owners run 3S and larger 5000mAh packs, while others found the tray too short for certain shorty or 3S batteries, with one reporting a 53mm maximum width and another saying the tray sits too low and rubs against links. Installation and fit with some bodies and crossmember setups required modification for a few owners. Reviews cover the TRX-4 Sport, Defender and Blazer variants.
