2018 All-new Features:
- Recent EOS Champion, European Champion, USA Champion and World Champion platform
- Redesigned chassis accommodates new lower motor mount to decrease the CG
- Lower motor mounts decrease the weight position of motor and central slipper clutch/diff, improving cornering speed and stability
- Redesigned lower composite central bulkhead fits the new lower alu motor mount
- Redesigned side guard allows motor to be positioned lower
- Improved shock absorber lower shims give more precise shock shaft movement
- Improved construction and production details on both front & rear differential crown gears results in quieter operation and increased reliability
The new XB4 chassis was redesigned with the main focus to lower the CG to improve cornering speed and stability. The new chassis accommodates the new lower motor mount.
CNC-machined from high-quality Swiss 2mm 7075 T6 aluminum, the chassis is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity; additionally black-coated for increased lifespan.
Weight distribution, chassis width & length, and proper flex have key influences on the handling of the car. All of these features were incorporated into the design of the chassis.
The all-new lower motor bulkhead decreases the weight position of motor and central slipper clutch/diff, improving cornering speed and stability.
Machined from the premium Swiss 7075 T6, the motor bulkhead is strong and lightweight.
With the lower CG design focus on the new XB4, the central bulkhead was lowered as well.
The graphite central upper deck holds ball-bearings in the motor mount and bulkhead assembly, while the upper deck allows easy access for slipper clutch adjustment.
The side guards were redesigned to allow the motor to be positioned as low as possible on the chassis to improve cornering speed and stability.
Tough composite side guards perfectly fit the chassis to seal against dirt and protect from side impacts.
Molded from a hard composite material, the side guards are an important part of the chassis flex adjustment for the majority of track conditions. For very-low-traction tracks, optional medium stiffness side guards are available.
To improve the precision of the shock shaft movement, the front composite shim was redesigned and updated with a more accurate mould design.
Well-built, reliable shock absorbers are extremely important for super-smooth suspension action on any type of track. The shocks on the XB2 have been specifically designed to be built easily, perform consistently, and last reliably. Careful attention was paid to the smallest details during the design process, as well as during long-term testing in various conditions.
The shocks are membrane-free, yet they still allow for easy, consistent building and rebound setting using the bleed-screw shock cap design.
Downstop is adjusted using composite shims under the pistons. Upstop travel is adjusted using composite shims under the shock collar.
The aluminum body, lower nut, and bleeder shock caps are all machined from premium Swiss 7075 T6 aluminum.
Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.
To improve the reliability of the differential and ensure quieter operation, both front and rear differential crown gears construction and production details were improved.
Both front & rear diff crown gears and pinion gears are made from steel which has been additionally hardened to ensure increased lifespan and reliability.
For clay and low-traction tracks, optional graphite diff crown gears can be used for increased traction.
