TRX-4® Land Rover® Defender® delivers innovation versatility, and capability to match its incredible scale looks. Underneath the rugged body TRX-4 Defender is built with extreme capability to take your off-road adventures to new heights. Portal axles deliver maximum ground clearance that turn “no way” into “no problem.” Whether you are enjoying outdoor trails or getting technical on the rocks, the remote-locking front and rear differentials and high/low range transmission provide unmatched driving versatility.
Features may include:
CHASSISA thick 1.5 mm 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.
The innovative shock towers allow four separate “bolt-on” wheelbase positions: 300, 312, 324, and 336 mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.
DRIVELINETRX-4's portal axles lift the differential pumpkin to provide incredible ground clearance. This radical design also improves axle geometry and reduces strain on the driveshafts. Steel gears ensure trouble-free performance, no matter how technical the climb.
On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. TRX-4’s radical portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis. Total axle gear reduction is over twice non-portal designs so Titan motor torque delivers smooth forward motion, not frame twist.
GEOMETRYTRX-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.
The steering link and drag link attach high on the portal axles, raising them away from possible damage. This allows TRX-4 to attack obstacles head on, reducing the risk of hitting the steering linkage on rocks.
ELECTRONICSHV 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. Crawl profile introduces hill hold and instant reverse for extremely technical courses. Either will help you navigate the trail with ease.
Torque rules the trail and 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.
