Rear Suspension Upgrade for NT1

The XRAY 333712 Aluminum Rear Suspension Holder is a high-precision upgrade for NT1 series chassis. This one-piece rear holder integrates the bulkheads to sharpen centering and boost stability under hard cornering and high speed runs.

Reworked Mounts for Tunable Flex

The rear arm mounts have been revised to accept the square composite bushings used on XRAY T4 and XB4 cars. These bushings preserve vertical adjustment of the inner hinge pins while allowing you to change pin width, giving practical roll center and geometry options for on-track tuning.

Slim Profile to Boost Traction

The slimmer aluminium profile brings the suspension arms closer together, increasing rear traction. That tighter mounting layout helps drivers extract more grip and control during acceleration and mid-corner transitions.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is the XRAY 333712 holder backwards compatible with older NT1s?

Yes. The aluminium holder keeps compatibility with prior NT1 versions while adding more tuning flexibility thanks to its integrated bulkhead layout.

What does the square bushing swap achieve?

Switching to the square composite bushings maintains hinge pin vertical position and lets you alter pin spacing, which directly affects roll center and handling balance.

Will I need other parts to use this holder?

Most installations use existing NT1 components, but you may want to revisit hinge pin settings and anti-roll adjustments to get the best performance from the new holder.
