| Chassis. |
|
| The chassis plate is updated for the new split radio box mounting configuration that helps to significantly improve overall traction and ensures perfect & balanced side-to-side flex. |

|
| Radio Box. |
|
The radio box features new split design that ensures a perfect left to right side flex characteristics that helps to generate more overall traction. All the electronics are mounted inside of the temperature resistant Hard composite box. This flex configuration and material composition improve the overall traction of the car.
The radio box is fitted to the chassis with three screws in front and three screws in the rear to achieve perfect stability for the servo mounting. To facilitate easier handling, the front and rear sections of the box are connected at the bottom.
The electronics assembly is very compact and can be quickly & easily removed for servicing and cleaning. It requires removing only a few screws from the bottom of the chassis to remove the entire electronics assembly from the car.
The large, molded radio box features a very clean design and layout that places the weight in key areas for proper balance. The batteries are placed along the front centerline of the chassis, while the lighter receiver is placed on its side at the rear. The easy-access radio box is mounted on the side of the car and is secured by the fewest possible screws. |

| Shock Towers. |
|
New Swiss 7075 T6 aluminum shock towers feature lowered shock mounting positions for both the front and rear suspension. The lower mounting positions increase the overall stability of the car across all surfaces, as well as help increase cornering speeds. By carefully selecting the new tower geometry, the single row of shock mounting positions simplifies the set-up process to optimize performance for any track condition.
The front & rear shock towers are CNC-machined from 4mm Swiss 7075 T6 aluminum for strength and durability. The front shock tower features 4mm shock mounting holes for increased durability and rigidity. |

| Shocks. |
|
The new XB8 shock bodies and shock shafts were shortened to match the new lowered shock towers and lowered mounting geometry, while maintaining proper suspension travel.
The shorter XB8 shocks carry over multi-adjustable 3-in-1 shock caps with 4 bleed holes with 3 different seal choices – ribbed membrane, cell membrane, or O-ring. The shorter shocks feature 3 different assembly alternatives – emulsion / rebound / zero rebound, with each one suitable for different track conditions.
The lower shock ball joint features a lock extension that fits into the lower collar, reducing the chances of the retainer separating from the ball joint and unseating the spring in a crash.
Oversized big-bore shocks featuring 16.2mm I.D. shock bodies and are externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hard coated in a titanium color and feature a 1-piece aluminum lower cap.
The XB8 comes with 4 Dots front springs and 3 Dots short (82mm) rear springs. |

| Shock Cap 3-in-1. |
|
3-in-1 shock caps allow assembly in 3 different configurations – emulsion / rebound / zero rebound, to match shock dampening characteristics to various driving styles and different track conditions.
The Emulsion configuration uses an O-ring to seal cap to body, mixing oil and air inside the shock. Typically provides excellent traction on a variety of surfaces and is suggested as a starting point for most typical track conditions.
The Rebound alternative using the cell membrane is best matched to lower traction and flat slippery tracks. This shock set-up has the most rebound out of the three build options.
The Zero Rebound configuration created by using the ribbed membrane is better suited for super bumpy tracks. This set-up has no rebound. |

|
| Diff Bulkheads. |
|
The new front & rear gearbox front cases were modified with provisions for the anti-roll bar centering collars. The new anti-roll bar collars minimize unwanted movement and improve the precision of the anti-roll bar functionality.
Front & rear bulkheads feature a semi-split design for easy diff access while adding the valuable diff height adjustment. The bulkhead also aligns the front central driveshaft with a reduced operating angle for less friction and reduced wear on the CV joint components and improved driveline efficiency.
The XB8 bulkheads allow fast and easy differential access for setup changes or servicing by removing only 4 screws from the upper gear box cover while the lower section remains mounted to the chassis with the lower arms and suspension holders installed. This super-fast diff access is featured on both the front and rear gearboxes. |

|
| Anti-Roll Bars. |
|
To increase overall traction in all track conditions, the front anti-roll bars used are 2.2mm and the rears to 2.4mm.
Anti-roll bars, manufactured from spring steel material, are easily mounted to front & rear diff cases with easy adjustment using the adjustable linkages.
Anti-roll bar wires of different thicknesses are optionally available for fine-tuning. |

|
| Steering Block. |
|
| Steering blocks from a harder composite material provide a more responsive feel especially on bumpy tracks and retain free suspension movement in dusty conditions for better consistency. The steering blocks are super lightweight yet extremely strong, featuring a larger outside 8x16x5mm ball-bearings for increased reliability and lifespan. |

|
| Ackermann. |
|
The all-new 3 dots carbon steering plates update Ackermann geometry, improving the stability and cornering speed of the car. The new geometry features increased Ackermann, with the outside wheel turning less, which yields improved drivability and lowered lap times.
The specially designed ball studs increase steering lock and allow greater steering radius. The integrated backstops ensure that the pivot balls do not disconnect in crashes.
Ackermann can be easily adjusted on the machined Swiss 7075 T6 steering plate as well to ensure highest reliability and strength. |

| Suspension Holders. |
|
Front & rear suspension holders for semi-split bulkheads offer an expanded range of set-up adjustments. The front upper suspension arm holder is also updated for the semi-split bulkhead.
The aluminum suspension holders feature Integrated Suspension Settings™ (I.S.S.) which allows for quick & easy suspension geometry setting.
Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the XB8 suspension geometry can be completely adjusted in mere seconds.
Machined from premium Swiss 7075 T6 aluminum and black coated. |

| Alu Wheel Hubs. |
|
To improve the out-of-the-box geometry, the XB8 now includes both front & rear wheel hubs with a +1mm off-set which is the most favorite choice for most of the track conditions.
Ultra-lightweight 17mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum.
The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting. |
