XRay X1 20 Aluminium Rear Bulkhead Left - XR373027

The XRay XR373027 X1 20 Aluminium Rear Bulkhead - Left is a redesigned component engineered to work with the independent wing mount system. The updated layout allows the differential to sit 0.5mm lower, expanding the available range for rear ride height tuning. CNC-machined from premium Swiss 7075 T6 aluminium and black coated, it combines reduced weight with reinforced strength to help resist bending during impacts.

Key Features

• Redesigned LEFT rear bulkhead for the independent wing mount system
• Lowers diff position by 0.5mm for a greater ride height adjustment range
• CNC-machined from premium Swiss 7075 T6 aluminium with durable black coating
• Strategically lightened while retaining strength for reliability
• Lower, lighter bulkhead and upper clamp for an ultra-low rear centre of gravity
• Quick and easy ride height adjustment without dismounting the car
• Includes ride height shims for ultra-fine 0.25mm adjustment increments
• Reinforced design to minimise the chance of bending in crashes
• Must be used with right rear bulkhead #373017

The ride height system uses shims inserted between the bulkhead and upper bulkhead clamp, enabling precise 0.25mm steps compared with previous 0.5mm increments using eccentric bushings. Designed for the XRay X1 20, this LEFT-side part is ideal for precise rear-end tuning and consistent performance.
