The XRAY 303353 hard composite right rear upright is a precision replacement part that helps control rear-end behaviour. Its 1° outboard toe-in encourages better rotation through corners, with the hard composite tailored to foam tyre use while remaining effective for rubber tyres.
Two selectable roll centre locations on the upper part let you fine-tune suspension response for different circuits. The upright takes compact 5x10 ball bearings to keep unsprung weight down and steering feel direct. The hard material preserves suspension geometry under race stresses.
Match this right-side upright with left-side model 303363 for consistent balance. Alter roll centre and small toe tweaks to tune XRAY 303353 to the grip and tyre combination you run.
