• High-Precision Metal Gears — Each differential is assembled with high-precision metal gears rather than nylon or plastic, guaranteeing long-term durability, reduced wear and confidence under demanding racing and bashing conditions.
• Fully Adjustable Suspension Tuning — Double-wishbone suspension with fully adjustable turnbuckles on all four corners allows you to fine-tune ride height, camber, anti-roll bar stiffness and shock preload to achieve perfect handling for any surface, from smooth tarmac stages to rough gravel.
• Front CVA Driveshafts — Constant-velocity driveshafts at the front deliver smooth power transfer whilst maintaining steering geometry, eliminating torque steer and providing predictable cornering behaviour.
• Rubber Sealed Ball Bearings — All bearings feature rubber seals that keep dirt, mud and moisture out whilst retaining essential lubrication, extending bearing life and maintaining smooth rotation even after wet or dusty sessions.
• Sealed Drivetrain and Underbody — The drivetrain and underbody panels are sealed to keep debris and moisture out, significantly reducing cleaning time and prolonging component lifespan between services.
• Protective Inner Chassis Body — An inner chassis body protects the internal drivetrain and electronics from impacts, mud spray and damage during rugged off-road use.
• Mounted Rally Tyres and Wheels — The chassis comes complete with low-profile gravel-spec tyres and wheels already mounted and balanced, ready to hit the ground running with consistent traction out of the box.
• Compatible with 2S and 3S Brushless Systems — The R4 is engineered to handle the latest 2S and 3S LiPo brushless power systems, offering flexibility in performance levels and runtime depending on your battery choice.
• 190mm Body Compatibility — The 260mm wheelbase and 190mm width are designed to accommodate 190mm-wide rally and drift bodyshells, opening up a huge range of body options from different manufacturers.

Technical Performance

The FTX R4 Rally represents a significant step forward in roller chassis engineering, combining professional-grade materials with intelligent design. The 2.5mm aluminium chassis provides the perfect balance between strength and weight, whilst the suite of CNC-machined aluminium components ensures precise alignment and consistent performance lap after lap. The inclusion of carbon-fibre shock towers and servo plate—features normally found only on premium upgrade parts lists—demonstrates FTX's commitment to delivering exceptional value. The 4WD drivetrain with its three-differential layout provides genuine four-wheel drive traction, superior to simpler 2WD designs, making this chassis equally at home on carpet rally stages, gravel rallycross courses or muddy countryside terrain. Each differential uses high-precision metal gears, a crucial specification for durability and consistent power delivery under high-load conditions. The double-wishbone suspension with independent adjustment at all four corners offers genuine tuning flexibility—whether you need a stiff setup for high-speed stability or a softer, more forgiving setup for technical terrain, you can dial in the perfect balance. The engineered 260mm wheelbase and 190mm track width create a planted, stable platform that's forgiving enough for intermediate drivers yet sophisticated enough for competitive enthusiasts seeking precise control and fine-tuning capability. With support for 2S and 3S brushless motor systems, you can choose between efficient, extended-runtime setups or maximum-performance high-powered configurations depending on your needs.
