Molded composite steering block from specially-formulated graphite composite material is a perfect balance between reliability and performance. Compact yet rugged steering blocks are molded from a special composite mixture for maximum strength, perfect for high-traction conditions. The graphite steering blocks make the car more stable and increase cornering speed.

For maximum drivetrain reliability, larger 5x12mm ball-bearings are used in the outer position with increased dynamic load. On the inner position, smaller 5x10mm ball-bearings are used to minimize unsprung weight.

Gear differential internal gears precision made from new graphite composite mixture. Includes 2 bevel gears + 4 satellite gears. Molded from an all-new special lightweight and extra-strong graphite material which gives the gears an optimal balance of hardness, toughness, and flexibility to provide long life, minimal wear, and minimizing breakage or teeth stripping. The lighter, graphite gears result in increased drivetrain efficiency. A "must have" for professional racers.

Gear differential cross pin made from tough composite material. Fits #304900 composite gear differential.

Front & rear lower long suspension arms made from graphite material suitable for most track conditions. Longer suspension arms have redesigned geometry for improved handling, increased traction and improved handling on bumpy tracks.

The design of the arm allows for a greater range of adjustments.

The arm also features a mounting position for the optional anti-roll bar.

Super-compact rear upright, CNC-machined from high-grade Swiss 7075 T6 aluminum, featuring multiple set-up options for upper & lower roll centers.

Upper roll center is adjusted with the camber linkage via shims in all directions – up/down & in/out. Lower roll center is adjustable via eccentric inserts in 9 different positions – up/down & in/out.

The race-proven, 2-piece design allows fine-adjustment and increases durability as well performance. Using the aluminum uprights make the car more stable and increases overall side grip and forward traction. Traction under braking is also improved.

The upright fits on both left & right sides. Must be used with the longer drive shafts.

XRAY ECS Drive Shaft in length 83mm with 2.5mm pin. The XRAY’s unique ECS Drive Shaft equalizes the speed between the drive shaft and the wheel.

With a unique 2-piece joint between the axle and the wheel, the same extreme wheel turning angle is divided into two shallower angles without joint binding. This means that at the same cornering speed, the inner wheel will not bind or vibrate. Drive through the corner is more stable, more precise, and easier to drive. The ECS Drive Shafts help also with improved landing after jumps.

With the ECS drive shafts, wheel vibrations and noise are decreased to minimum, steering is increased, stability of the car is increased and cornering speed and smoothness are noticeably increased as well. A must have option part.

Direct aluminum replacement of the lower composite central bulkhead for better reinforcement, greater reliability, and longer life. CNC-machined from premium Swiss 7076 aluminum and additionally black coated and laser engraved. Redesigned to lower the CG.
