Introduced in 1969, the Chevrolet Blazer was General Motors’ two-door entry into the booming sport utility market. Its shorter wheelbase and capable suspension instantly made it a favorite in the 4X4 world, earning the love of enthusiasts and collectors. Traxxas honors the rich history of the Blazer with this beautifully detailed reproduction of the 1979 K5 Blazer built on the renowned TRX-4® chassis. Outfitted with replica Rally wheels, a highly detailed chrome grille, and a full complement of scale details, the TRX-4 Blazer combines the iconic style of the Blazer with toughness and technology that could only come from Traxxas.
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.
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.
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.
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. A secondary front-mounted battery tray accepts smaller 1/16 scale Traxxas batteries to position weight directly over the front axle for maximum climbing traction on technical climbs.
Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of the chassis.
Oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out even the roughest trails. These silver-anodized aluminum shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.
The TRX-4 uses tough hex hardware throughout for improved strength and easy servicing.
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. The 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.
Conventional crawlers equipped with axle spools sacrifice turning radius for traction. Traxxas gives you the freedom and versatility to lock and unlock both the front and rear differentials to suit your driving needs, all controlled remotely from your transmitter. Leave the differentials unlocked for relaxed driving on the trail with smooth, tight turning and better handling at high speeds. When the trail gets technical, lock the front and rear differentials, or just the front differential, for superior pull and grip over extreme terrain. New sleeved micro cables control the differential action for scale appearance, without limiting the huge suspension articulation.
Why carry your crawler down the trail when you can drive? The TRX-4 features a high speed gear to get you to your next crawling challenge quickly. When you get there, flip the rocker switch on your transmitter to engage low range and conquer tough terrain with exceptional torque.
Hardened steel U-joints on the front and rear driveshafts provide smooth, reliable power delivery for non-stop fun.
A twin friction plate slipper clutch provides some additional protection from motor stalls in extreme crawling conditions.
Black sealed ball bearings resist mud and dirt to keep your rig rolling smoothly.
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.
With the front differential unlocked, the superior 45-degree steering angle negotiates around even the tightest bends with ease. This helps avoid awkward reversing maneuvers in tight spaces.
With a 59 degree out-of-box approach angle in the front, TRX-4 is ready to climb walls. An equally impressive 47 degree rear approach angle provides extreme capability, even in the deepest ruts.
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.
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.
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.
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.
A new full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough challenges.
The Traxxas TQi radio system features exclusive cruise control for long-distance treks. Set your speed using the transmitter and then use the multi-function knob to fine-tune it faster or slower to match your pace. The grip-mounted rocker switch selects high or low range gears to suit the terrain while a separate toggle switch engages or disengages the locking differentials, all on the fly. Best of all, the TQi is compatible with the #6511 Wireless Module so you can set up everything right from your smartphone.
TRX-4 uses three fully-waterproof micro servos to actuate the front and rear differentials as well as the high/low range selection on the transmission. Sleeved micro cables eliminate complicated linkages that would otherwise limit suspension articulation.
The Blazer’s LED light kit takes scale realism to the next level with working headlights, tail lights, and side markers. Fully waterproof and built Traxxas-Tough, the LED light kit is ready for your wildest adventures. No matter where the trail leads, day or night, the TRX-4 Blazer will forge a path.
The Chevrolet K5 Blazer replica from Traxxas takes you off-road in classic 1970’s style. Bright chrome trim highlights the beautiful two-tone paint and clear windows. Replica decals complete the authentic look for maximum impact on the trail. Available in orange or red, these custom-painted classic K5 Blazer bodies give Chevy fans a reason to cheer.
The TRX-4 Blazer rides on 1.9” replica Rally wheels that are accurate down to the smallest detail. Chrome replica locking hubs hide the wheel nuts for true authenticity. The 1.9” Rally wheels come pre-glued and mounted to aggressive, S1-compound Canyon Trail tires for rugged climbing action. A standard 12mm steel hex makes the TRX-4 chassis compatible with popular 1.9” wheel and tire combinations.
Tough inner fenders mount directly to the frame and shock towers to provide substantial look and feel to the TRX-4. The authentic realism adds to the fun while also helping to keep rocks, mud, and twigs out of the chassis.
Functional rock sliders help prevent damage and provide extra support for the body. The additional bracing adjusts for different widths.
The TRX-4 Blazer gets the full Traxxas treatment with unsurpassed realism including a chrome grille, bumpers, wipers, and door handles. These classic touches are authentic down to the smallest details including light buckets and reflectors in the headlights and tail lights.
Classic style meets modern technology underneath the Blazer with realistic mirror chrome differential covers. These polished details take the scale look of the front and rear portal axles to the next level.
The TRX-4 Blazer features beautiful precision molded details for a whole new level of scale realism. The authentic chrome wheels, side mirrors, and windshield wipers provide the perfect scale touches.
