AARMA 1/8 QUAKE 4S DSC 4X4 RTR Brushless Monster Truck , Black/Red # ARA4437T1

The ARRMA® QUAKE™ 4S DSC 4X4 RTR unleashes seismic 4S brushless power in a bigger 1/8 scale monster truck. A high-CofG chassis delivers dynamic monster truck stunts, Spektrum DSC keeps it controllable, and a low-component design keeps maintenance quick.

ARRMA 1/8 QUAKE 4S DSC 4X4 RTR Brushless Monster Truck Introduction

The aftershock has arrived.

The QUAKE 223S and QUAKE GROM started the rumble. The ARRMA® QUAKE™ 4S DSC 4X4 RTR takes it to a scale that shakes the ground under your feet. This is the first vehicle built on ARRMA's Next Gen 4S platform: a bigger 1/8 scale footprint, serious 4S brushless power, and a tough, low-component design that gets you back to bashing faster.

Real monster truck attitude starts with the chassis. The high center-of-gravity design leans hard into corners like full-size machines and lifts the front wheels on demand. A raised chassis adds ground clearance for the rough stuff, a high-angle integrated wheelie bar sets up seismic stunts, and cut chevron tires bite in and shake the ground on dirt, grass, and gravel. Power reaches all four corners through a three-differential 4WD drivetrain that keeps the pressure planted no matter how ugly the landing.

Under the body sits a full Spektrum™ 4S power system. The Firma™ 150A Brushless Smart ESC V2, 3S - 4S: IC5 runs 3S or 4S, feeding a Firma 3674 2300Kv brushless motor topped with a heatsink and cooling fan. A high-airflow fan cover and integrated chassis cooling pull fresh air in from the ground up, so the heat stays down when the runs get long. Separate ESC and receiver maximize response and reliability when you're asking everything of it.

Big power is only fun when you can steer it. Spektrum Dynamic Stability Control (DSC) automatically applies steering correction for easy, controllable sideways action, sensing oversteer and adding counter steer before a slide turns into a spin. Four selectable modes let you choose how much help you want, from a confidence-building safety net to fully on your own. The Spektrum SLT3™ 2.4GHz 3-channel transmitter adds adjustable throttle limiting as you level up, while the S662 metal-geared waterproof digital servo, aluminum 25T servo horn, and heavy-duty sliding ramp servo saver keep steering precise and protected through brutal impacts.

Aftershock ready means built for the hits. A deep tub composite chassis wraps the electronics in protection and serious durability. Interlocking shock towers keep the suspension ready for the next landing, the high-angle integrated wheelie bar sets up seismic stunts, threaded aluminum shock absorbers with large diameter shafts soak up monster truck jumps, and shock-absorbing bumper braces plus a large-impact front bumper handle full-send collisions. Rear wishbone dirt guards keep flying debris out of the suspension, and interlocking body protection shields the internals from dirt and body punch-through.

Then it gets out of your way. The low component count makes maintenance simple, and a large battery compartment, ratcheting battery strap, easy-access retention system, and clean captive battery wiring make pack swaps fast. The hidden body retention system keeps the look clean and locked in with no clips to fight. Choose Black/Red, White/Blue, or the limited-edition iridescent Black/Pearl (U.S. Only – Available Exclusively at HorizonHobby.com).

Add a 3S or 4S hardcase LiPo and let the ground know you're coming. The ARRMA QUAKE 4S DSC 4X4 RTR is bigger, stronger, easier to maintain, and built to keep the aftershocks coming.

LIMITED EDITION BLACK/PEARL (ARA4437T3)

The iridescent Black/Pearl (ARA4437T3) trim scheme is a limited edition available only at HorizonHobby.com (U.S. Only). Same seismic performance, with a finish that shifts in the light.

SEISMIC MONSTER TRUCK FEEL

The high center of gravity chassis is tuned to move like the real thing. Huge leans through the corners, wheel-lifting launches off the throttle, and big-air landings that look as good as they feel. This is monster truck behavior, not a buggy in disguise.

SHAKE THE GROUND — NEXT GEN 4S PLATFORM

The QUAKE 4S is the first vehicle built on ARRMA's Next Gen 4S platform, bringing the QUAKE personality to a bigger 1/8 scale footprint. More size, more power, more presence, and more ground to shake.

DYNAMIC STABILITY CONTROL (DSC)

Spektrum DSC automatically applies steering correction for easy, controllable sideways action. It senses oversteer and adds countersteer to control over-rotation, with four selectable modes so you choose how much help you want. As your skills build, dial it back and run on raw ability.

AFTERSHOCK-READY DURABILITY

A super-tough molded composite deep tub chassis, interlocking shock towers, a large-impact front bumper, and shock-absorbing bumper braces are built to handle relentless hits. Wishbone dirt guards and interlocking body protection keep dirt and debris out of the parts that matter.

GROUND-GRIPPING TRACTION

A three-differential 4WD drivetrain keeps power planted at all four corners, while cut chevron tires bite in and shake the ground across dirt, grass, gravel, and everything in between.

SPEKTRUM 4S POWER SYSTEM

The Spektrum™ Firma™ 150A Brushless Smart ESC V2, 3S - 4S: IC5 runs 3S or 4S power into a Firma 3674 2300Kv brushless motor with a heatsink and cooling fan. Motor length is up from 68mm on previous 4S vehicles to 74mm on the Quake 4S, for greater torque. A high-airflow fan cover and integrated chassis cooling keep fresh air moving when the heat is on.

BUILT FOR EASY MAINTENANCE

A low component count means fewer parts to remove, fewer parts to lose, and less time between runs. Easy access to the drivetrain, electronics, and battery gets the QUAKE 4S back out and ready for your next rampage.

FAST, SECURE BATTERY SWAPS

A large battery compartment, ratcheting battery strap, and easy-access retention system make installing and swapping packs quick. Clean, captive battery wiring keeps everything tidy and protected during hard bashing.

HIDDEN BODY RETENTION SYSTEM

No exposed clips, no fighting with posts. The hidden body retention system holds the body securely for a clean and locked-in look, and the internal body frame adds toughness where the hits land.
