Schumacher U8398 F1 Spool Axle Set – Icon/Icon2

The Schumacher U8398 Formula/F1 Spool Axle Set is a lightweight rear axle spool designed for precise handling on high-grip surfaces. It offers a direct, locked-axle feel that can enhance steering response, direction change, acceleration, and off-power stability into corners. Compared with a ball differential (U8186) or gear differential (U8180), a spool is particularly effective on carpet when running foam or rubber tyres.

Supplied as a complete unit with a lightweight carbon axle and an 88T 64DP spur gear, this set focuses on consistent drive and a connected rear end for confident corner entry. Schumacher part number: U8398.
