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.
