Racing Grade Rear Bulkhead Stiffener for XRAY NT1

The 3Racing XN1-31 is a purpose-engineered aluminium rear bulkhead stiffener for the XRAY NT1 chassis, designed to lower rear-end compliance under dynamic loads. Manufactured to tight tolerances, the component increases bulkhead stiffness to stabilise the rear roll centre and promote repeatable handling across fuel or battery cycles. Its lightweight aluminium construction balances strength with minimal mass, making it suitable for drivers aiming to fine tune rear traction and chassis balance without compromising responsiveness.

How does the stiffener influence tuning options?

By reducing rear bulkhead flex the XN1-31 narrows the range of chassis compliance, allowing more precise adjustments to anti-squat, toe and damping without unpredictable rear behaviour.

Are there recommended complementary upgrades?

Pairing the stiffener with refined shock valving or a firmer rear anti-roll bar can capitalise on the reduced flex to improve rotation control and mid-corner stability.

What inspection is advised after fitting?

Check mounting fasteners for torque after initial track sessions and inspect mating surfaces for even contact. Small shims or minor setup tweaks may be needed to achieve the desired balance.
