Heavy-Duty Steel Frame Rails:
A thick 1.5mm steel ladder frame with molded cross members provides exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid backbone lets the suspension do the work it was designed to do. You’ll feel the difference on trails where the elimination of chassis flex allows for precise wheel placement when navigating technical terrain.

Adjustable Wheelbase:
The innovative shock towers allow four separate “bolt-on” wheelbase positions: 300, 312, 324, and 336mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.

Molded Wire Retainers:
The finer details matter so we incorporated wire retainers into the frame rails, which provide a clean look and keep the wiring more secure from off-road hazards.

Dual Battery Tray:
TRX-4’s main battery tray accommodates a full-length 5000mAh 3-cell LiPo or 7600mAh 2-cell LiPo for extended run times or smaller 1/16 scale Traxxas batteries for reduced weight. A hinged battery strap provides quick and secure battery mounting without pins to lose in the field. The innovative strap flips over to adjust for different height batteries.

Heavy-Duty Steel Links:
Thick 5mm diameter steel links feature tough, fully-captured heavy-duty rod ends with steel hollow balls for exceptional strength and durability. This is one rig that won’t strand you on the trail with a broken suspension link.

Precision Hex Hardware:
The TRX-4 uses tough hex hardware throughout for improved strength and easy servicing. For extreme environments, consider using the Stainless Steel Hardware Kit ( tra8298 ).

Locked Differentials:
Full-time locked front and rear differentials transform the motor’s torque into unstoppable climbing action. With no slippage possible, all four wheels claw with equal traction, powering the lightweight Sport over the toughest obstacles.

Steel Gear Transmission:
The single-speed transmission is geared low for the raw torque required to scale the steepest grades. Steel gears provide the Traxxas-Tough durability that keeps you on the trail.

Raised Center Driveshafts and Suspension Links:
TRX-4’s radical portal axle design raises the driveshafts higher to improve axle geometry and reduce driveshaft angles. Higher driveshafts and suspension links pass over obstacles to avoid high-centering your truck and reduce overall grinding wear.

High Steering and Drag Links:
The steering link and drag link attach high on the portal axles, raising them away from possible damage. This allows the TRX-4 to attack obstacles head on, reducing the risk of hitting the steering linkage on rocks.

45-Degree Steering Angle:
The superior 45-degree steering angle negotiates around even the tightest bends with ease. This helps avoid awkward reversing maneuvers in tight spaces.

Extreme Approach Angles:
With a 58.82 degree out-of-box approach angle in the front, TRX-4 is ready to climb walls. An equally impressive 45.83 degree rear approach angle provides extreme capability, even in the deepest ruts.

High Ground Clearance:
Portal axles help raise the center ground clearance to an unparalleled 3.14 inches (80mm), while raised suspension links and driveshafts clear the rocks underneath. Superior capability equals more fun no matter where your adventure takes you.

Front Motor Design:
The TRX-4’s large 550 size brushed 21-turn Titan motor provides smooth reliable power and loads of torque to climb the toughest obstacles. The front mounted orientation moves the weight bias forward to get you up and over obstacles with improved traction.

New XL-5 HV ESC:
HV stands for compatibility with the high-voltage 3s LiPo battery packs for greater efficiency and power. In addition to the three standard profiles (Sport, Race, Training Mode®), the XL-5 HV features a Trail profile that serves up a little bit of drag brake for smooth intuitive driving for most of your adventures. A new Crawl profile introduces hill hold and instant reverse for extremely technical courses. Either will help you navigate the trail with ease.

Titan 21T 550 Motor:
Torque rules the trail! The TRX-4’s massive Titan 21T motor pumps out huge torque to get you up and over anything that gets in the way. An integrated cooling fan keeps temperatures down for extended run times.

Waterproof Metal Gear Servo:
A new full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough challenges.

TQ™ 2-Channel Radio System:
Switch on the power and drive! That’s all there is to it with the TQ™ 2.4GHz radio system. Race multiple vehicles side by side without interference. The TQ’s advanced programming provides long-range control with smooth, glitch-free performance and it fits comfortably in the hand for extended use.
