Purpose Built
The TRX-4 Sport combines the unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon® Trail tires, and a lightweight pickup truck body for a leaner, performance-focused new TRX-4. The Sport’s unique bumpers, wheels, and body were designed for increased climbing versatility. Whether it’s a fun trail run or a hardcore technical crawl, the TRX-4 Sport’s capability and performance-built approach takes your outdoor adventure to a new level.
Ultimate Ground Clearance
The
TRX-4 Scale and Trail Crawler is equipped right out of the box with
Traxxas' game-changing portal axle set. Portal axles lift the truck at
the wheels for huge center pumpkin ground clearance. In order to achieve
the same clearance with straight axles (and not get stuck), your tires
would have to be over an inch taller than the TRX-4's tires. Straddling
boulders with ease, the TRX-4 chassis definitely takes the path less
travelled and simply leaves all the others behind.
Torque Twist Eliminated
The
portal axles use gear reduction right at the wheels that dramatically
reduces undesirable torque twist. Total axle gear reduction is over
twice non-portal designs. The Titan 550 motor torque is translated into
straight, powerful, forward motion, rather than wasted energy twisting
your rig right off the rocks.
Improved Geometry
Portal
axle geometry raises the axle link mounts and center driveshaft,
greatly reducing critical driveshaft and suspension link angles. This
means less strain on the driveshafts, and the higher suspension links
provide greater clearance with less scraping and dragging across the
rocks. The steering drag link and tie rod are also raised up and out of
harm's way.
Rigid Steel Frame
A
heavy-duty formed-steel ladder frame with molded cross members creates
an extremely rigid backbone that 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.
45° Steering Angle
Traditional
crawlers sacrifice turning radius for traction. The TRX-4’s remote
locking differentials disengage to take full advantage of its superior
45 degree steering angle. Once you clear the obstacle, re-engage the
differentials for ultimate traction.
Metal Gear Digital Servo
A
new full-metal gear digital servo gives you the durability and steering
authority you need to confidently and reliably power through tough
situations.
Waterproof
Traxxas
was the first to bring you fully waterproof RC vehicles years ago with
our innovative designs. The TRX-4 Scale and Trail Crawler is fully
waterproof for how you like to really play, not “splash resistant.”
There is a big difference. Traxxas’ patented innovation gives you the
freedom to tackle creeks, snow, and mud without worrying about water in
your electronics.
3S Power System
The
new XL-5 HV electronic speed control brings 3S LiPo capability for
stronger, more efficient running. New speed control profiles have been
added for smooth and precise control. A new Trail profile facilitates
smooth driving for most of your adventures, while a new Crawl profile
introduces hill hold and instant reverse for extremely technical
courses. Either will help you navigate obstacles with ease, right from
the start. Long run times, up to 2 hours, are possible with a Traxxas 3S
5000mAh iD LiPo battery pack!
Canyon Trail 1.9 Tires
The
1.9 Canyon Trail tires and tuned foam inserts are super-soft and grippy
to deliver superior bite on rocky surfaces with convincing scale
realism. The 12mm steel hex drive makes the TRX-4 chassis compatible
with popular 1.9 wheel and tire combinations.
Traxxas Tough
Leave
the tools in the bag! The Traxxas TRX-4 chassis is built to handle the
rigors of remote locations and all-day driving fun. The foundation
begins with a pair of 1.5mm thick steel frame rails. Large diameter
steel links and heavy-duty, extra-wide rod ends keep the suspension
firmly mounted. Hardened steel CV-style half-shaft joints are ultra
reliable, while the brushless-ready steel portal axle and transfer case
gears are smooth and quiet. Traxxas’ composite materials have been
refined over three decades for the ultimate in strength and durability.
Aluminum GTS Shocks
All
new oil-filled coil-over GTS shocks were created exclusively for the
TRX-4 chassis. These silver-anodized aluminum units deliver silky-smooth
damping performance and feature threaded shock bodies for easy ride
height adjustments. The convincing scale realism looks great and they
perform even better with an O-ring cap seal and dual X-ring shaft seals.
Extreme Capability
Steep
approach angles front and rear allow the TRX-4 Scale and Trail Crawler
to tackle big obstacles head on. The front motor design biases weight
forward for superior climbing ability compared to other designs.
