3RACING Cactus 2WD Rear Upright CAC-316 Aluminium Upgrade  [CAC-316]

Track-focused rear upright for the Cactus 2WD

The 3RACING Cactus 2WD Aluminium Rear Upright CAC-316 boosts rear durability and steering accuracy for drivers who push hard. The CNC finish enhances fitment and cuts play at pivot points to deliver cleaner turns.

Consistent geometry under load

Precision machining helps the upright maintain correct suspension angles, reducing unwanted movement that can blur steering feel. This stability is useful for repeatable setup and tuning sessions.

Simple install, reliable gains

The CAC-316 fits existing mounting points so installation is straightforward using standard hobby tools. The modest weight keeps acceleration and handling predictable while reinforcing the rear end for rough tracks or circuits.
