The Slice S4XU is an awesome upgrade for you Slash 4x4 LCG. This model only fits the LCG version of the truck. It will not work on the the original Slash 4x4. The HCG version! I make a different chassis for that. The Slice S4X v5.
This chassis is super strong. No more broken chassis every time you have a bad crash. The structure also has a slight performance improvement. The weight of the electronics is better distributed. The battery is held in with one velcro strap. Of you choosing. Its not included with the kit. Everything else is Bolt On. No mods or extra parts needed. The chassis comes assembled. Just bolt on your front and rear ends. Install your electronics. And Go. It weighs right about the same as a stock truck! It will hold a 2s or 3s 5000 mah batteries. Others can possibly fit. But its up to you to mod it a little. The chassis plates are made of high quality G10 fiberglass composite. It will take a thread if you want to mount something. Or just drill a hole slightly smaller then the bolt. And a 3mm bolt will thread into it. Any 550 or long motor will fit. Even some 1/8 scale motors will fit.
