Mounted on the front portion of the upper deck to increase rigidity and steering response. Rigidity can be adjusted by using a combination of fixing screws.
Machined from high quality A7075 aluminium material. IF18-2 knuckle upper and lower insert. Prevents misalignment during a crash and enhances steering response during cornering. This bushing is used for central alignment of the upper pivot (0mm kit standard zero offset).
When assembling these parts first remove the front knuckle upper. Place the offset bush into the knuckle upper from the outside. Then pass both M3x14mm slim head screws through the knuckle upper from the inside and tighten the 3mm nylon nut on the outside.
New 0.8 module spur gear designed for high precision, high strength, and high durability. Gear specifications have been redesigned to provide uniform backlash for all tooth number combinations. The tooth width of the 2nd gear spur gear (R0409T56-T58) has been increased by approximately 12% to achieve even higher strength and durability. *Cannot be used in combination with conventional 0.8 module spur gears (R0247-60-62 and R0248-56-58) to prevent gear breakage. *Pinion gears for IF18-3 (R0384T18, R0384T19, R0385T23, R0385T24) must be used.
Not only has rigidity been increased by using A7075, but the pivot height has been raised by 2mm compared to the standard part R300B/300H, providing more responsive steering and changing the camber change rate. To ensure clearance inside the wheel, the ball has been downsized from 8.5 to 8.0mm and the screw cap from 10 to 9mm and tilted by 10°. A specially prepared 8mm titanium ball is included to ensure proper steering angle. The main body is hard anodized.

Weight has been reduced by F:0.3g R:0.5g, removing this unnecessary material has improved rotational balance. Reduced clearance in the thrust direction helps maintain wheel stability during running.
Compared to the kit-standard O-rings, the slightly harder compound generates subtle friction with the shock shaft, enhancing support rigidity. This helps suppress chassis roll and improves stability on high-grip or flat surfaces.
