Transform Your TRX-4 Defender into an Off-Road Beast!

The Traxxas TRX-4 is one of our favorite trucks for customization because there are just so many options and ways to customize this popular RC crawler. It was hard choosing just one for our Christmas build list, but we decided to go with our 4-part Ultimate Defender Trail Truck build. From 1.9” true beadlock wheels to aluminum suspension components, revised axle ratios, and LED lights, our Ultimate TRX-4 build really has it all. Any TRX-4 model rolls out of the box ready for hardcore trail action, but fully-outfitted, our TRX-4 Defender is an absolute trail beast! See it in action below or visit the Ultimate TRX-4 Defender Build to see how to make one of your own.
