The Traxxas TRX-4 chassis kit puts the innovative technology and rugged durability of the TRX-4 platform into your hands as a build-it-yourself kit. Experience the satisfaction of assembling your own portal axles, high/low range transmission, and remote-locking differentials, all neatly organised in labeled bags with a fully illustrated colour manual. Key components like the waterproof electronics and pre-assembled shocks and suspension links ensure a smooth and enjoyable building process.
This kit offers the freedom to customise your crawler with any accessory Traxxas 312 mm wheelbase body (sold separately) using the convenient clipless body mounting system. The heavy-duty 1.5 mm steel ladder frame provides exceptional torsional rigidity, allowing the advanced suspension system to work effectively on challenging terrain. With features like the remote-locking T-Lock differentials and the 2-speed high/low range transmission, the TRX-4 kit delivers extreme off-road capability and versatility.
Enjoy clipless convenience! Heavy-duty mounts integrated into rugged inner fenders provide a secure grip for compatible TRX-4 bodies (sold separately). Scale bumpers feature authentic recovery D-rings and accessory compatibility. The inner fenders protect the chassis from debris and are also LED rock light ready.
Built Traxxas tough! A thick 1.5 mm steel ladder frame with moulded cross members provides exceptional torsional rigidity. This extremely rigid backbone, combined with large diameter steel links and heavy-duty, extra-wide rod ends, ensures extreme durability on the most challenging trails you can find.
Master any terrain with ultimate control! Shift into low range for incredible 4-wheel drive pulling torque or high range for blasting down the trail, all from your transmitter. Remotely lock and unlock the patented front and rear T-Lock differentials to suit your driving needs instantly.
These 1.9″ Canyon Trail tyres and tuned foam inserts are super-soft and grippy. They deliver superior bite on rocky surfaces with convincing scale realism. Their aggressive tread finds traction on nearly any surface. A durable 12 mm steel hex drives the tough trail wheels.
Innovative oil-filled coil-over GTS shocks deliver silky-smooth damping performance on the trail. They feature threaded shock bodies for easy ride height adjustment, an O-ring cap seal, and dual X-ring shaft seals for leak-free operation. Their robust design ensures long-lasting, consistent performance soaking up the toughest terrain.
Build the power of portals! These innovative axles lift the chassis at the wheels for huge centre pumpkin ground clearance, virtually eliminating torque twist. Improved geometry raises key components like link mounts and driveshafts, reducing critical angles for extreme capability over obstacles, taking the path less travelled.
Torque rules the trail with the TRX-4! The massive Titan 21-turn 550 motor pumps out huge torque to get you up and over anything. The waterproof XL-5 HV ESC brings 3s LiPo capability and trail-tuned profiles like Crawl mode with hill hold and instant reverse for tackling extremely technical courses with ease.
A full-metal gear digital servo gives you the durability and steering authority needed to confidently power through tough situations. Combined with a superior 45° steering angle (with front diff unlocked), you can negotiate around even the tightest bends with ease, avoiding awkward reversing manoeuvres in tight spaces.
Tackle big obstacles head on! Steep approach angles front and rear allow the TRX-4 crawler to climb confidently over large obstacles. The front motor design biases weight forward for superior climbing ability on steep ascents. It's built for hours of driving fun and exploration on challenging terrain.
The Traxxas tough foundation includes hardened steel u-joints and brushless-ready steel portal axle and transfer case gears. Black sealed ball bearings resist mud and dirt to keep your rig rolling smoothly. Hex-drive hardware provides more positive and secure connections than other fasteners, with a rust-resistant black-oxide finish.
Your RC experience isn't limited by the weather! Only Traxxas’ patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water damaging your electronics. Drive anywhere, anytime, and experience true all-terrain capability and exploration fun regardless of the conditions.
Set your speed using the transmitter and fine-tune it precisely with the Multi-Function knob. Match the pace of trail companions or maintain a steady crawl over obstacles. This unique feature adds convenience and control for long adventures and navigating technical sections effortlessly.
