Details of all new parts:

New chassis

New narrow, straight chassis is more flexible in longitudinal direction yet is stiffer in lateral direction. CNC-machined from Swiss 7075 T6 aluminum, hardcoated for durability and long life.

XRAY Multi-Flex™

XRAY Multi-Flex™ has been now applied to off-road, giving super-easy chassis flex adjustment for traction and stability adjustment. An exclusive XRAY innovation.

Radio plate

All-new radio plate design incorporates a new compact composite radio box. Batteries are now located to front for better balance. Clean and smooth 1-piece plate design.

Side guards

Tough composite side guards give improved side protection, fits perfectly to chassis to seal against dirt, and protects the fuel tank. Features integrated Multi-Flex™ adjustment.

High-downforce body

New-concept high-downforce body is designed to work with the new high-downforce wing for incredible handling. Features integrated side guides and gives improved engine cooling.

High-downforce wing


Improved drivetrain parts give increased reliability and efficiency along with lower mass. Made from world-renown HUDY Spring Steel™ and extra-hardened for superior performance and ultra-long lifespan.

Drivetrain efficiency

All-new drivetrain ratio gives increased efficiency and improved performance. Features the following gearing:

• 40T front diff gear
• 40T rear diff gear
• 12T front pinion
• 12T rear pinion
• 13T clutchbell
• 46T central diff

Reliable central driveshafts

All-new central drive shaft design gives increased reliability. The larger and stronger outdrives feature protective rubber boots, thick 3mm pins, and a protective locking ring. Made from extra-hardened HUDY Spring Steel™.

Shock towers

All-new shock tower design with one-line shock positions give optimized mounting positions. Lightweight but extra-thick graphite material.

Shock Absorbers

With all-new parts and construction, these big-bore, long-stroke shocks offer increased downtravel and increased reliability and performance.

All-new shock parts

All new shock parts include new hardcoated shock bodies, reinforced ball-joints, shock balls with increased movement. New lower shock nut gives superior shock shaft centering. Ultra-precise shock pistons feature 6-, 8- and 10-hole shock pistons. The new longer shock shafts and new shock collar combine to give increased downtravel. New ultra-fine shock protective rubbers give superior sealing against dirt.
