These front hub carrier arm mounts were designed and tested by the Kilic family, specifically for Mugen MBX8/8R (buggy and truggy).

This part allows for a 4mm reduction in bumpsteer (the height difference between the front upright and the Ackerman plate) compared to the stock position, improving steering response. Made of high-resistance 7075 aluminum and anodized in gray with the Ultimate logo. Each mount features laser-engraved R/L letters for quick position identification.

With this option, you achieve increased steering under braking (when the front suspension is compressed) and a more linear steering feel when accelerating, lifting off the throttle, or braking.

Features and adjustments:
The mount offers 3 positions for the link, replacing the two original Mugen parts (E2153 and E2168) and adding an extra position:

Inner position: ideal for low-grip conditions, allowing for more turn-in.
Outer position: for high-grip tracks, reducing turn-in.

If a different bumpsteer is desired, the height can be adjusted with ULTIMATE 0.5mm (UR1504), 1mm (UR1505), or 2mm (UR1506) washers until the Mugen parts' standard is reached.
