Review: Gr8 frame! - I'm wasn't the easiest to set up but with patience. I got it together seems very durable. And the functionality of this is great. You can adjust your shocks and everything. The weight is nice and light, but also quite durable, so it's nice definitely a good value
Review: Nice frame upgrade - Nice quality, fit and finish. I like this better than the carbon fiber version, as all the holes are threaded and you don't need all the lock nuts. It provides alot of mounting options for shocks, can be assembled for either the short or long(high trail) wheel base. It also works just fine with the Injora Cherokee body, and the Injora double decker battery/esc mount.

- Come with multiple shock mounting points for better suspension tuning.

### ⭐⭐⭐⭐⭐ Nice frame upgrade

### ⭐⭐⭐⭐⭐ Love it! Changing all my Trx4m's to this Chassis
*by K***Y on April 7, 2026*

Works great. I am converting all of my Trx4m's to this chassis. It's strong enough to handle hard falls. The adjustable shock tower positioning has been a game-changer for increasing the amount of flex. It also allows you to use "laydown" servo mounts, which really help to increase the amount of flex you can get out of these. It comes with every screw, spacer, nut, and washer to completely connect all of the various components like shocks, links, skid plate, etc. Came with extra screws that came in handy when other screws in other components stripped or fell out. I do recommend the double-decker battery tray, though, especially if you are running aftermarket Tx/Rx and ESC. It has instructions and pieces to fit with the High Trail (longer frame) or the standard (like the Bronco and Defender). The instructions could use some improvement but they are pretty easy to figure out. It's just a one-page "exploded" view diagram that shows each piece, each screw, nut, and bolt, where and where they go. It also shows the list of each screw, how many there should be, what bag they are in, etc. Honestly, great upgrade, great value for the price.
