Sharper Handling with the XRAY 363085 Tower

The XRAY 363085 rear graphite shock tower is made for the XB4 2021 series with the HS chassis format. Fabricated from 3.5mm graphite, it provides a stiffer mounting platform and denser upper shock positions to help drivers fine tune rear-end behaviour.

Setup Versatility for Track Conditions

This tower adds multiple roll centre settings and extra wing mounting holes so you can adapt the car's balance for varied circuits and weather conditions.

Specifications

  • Material: Premium-grade 3.5mm graphite
  • Compatibility: Fits XB4 2021 series
  • Features: Multiple shock and roll center positions

Aimed at racers who want firmer rear support and more precise tuning choices during setup and race day adjustments.
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.

Does this fit my existing XB4 2021 parts?

Yes, it is designed for the XB4 2021 HS chassis and uses the same basic mounting layout, though you should verify hole alignment before final assembly.

How does it affect corner entry and mid corner balance?

The increased stiffness and altered shock geometry typically sharpen corner entry and can shift mid corner balance; tuning shock settings and anti-roll pairs will help refine handling.

Are there recommended upgrades to pair with this tower?

Complementary upgrades include firm rear shock cartridges or alternative anti-roll setups to take full advantage of the tower's stiffer mounting points.
