Rear Suspension Upgrade for Cleaner Handling

The XRAY 363123-H Hard Composite Rear Left Suspension Arm is a precision upgrade for racers wanting more consistent handling and durability. Built for the XB4 2020 Specs, this arm blends extended geometry and reinforced material to deliver steadier lap times and reduced wear.

Extra Length to Improve Traction

The arm is 2mm longer than standard units, which helps increase grip when traction is limited while keeping the car stable on sticky surfaces. Its layout supports alternate shock locations so drivers can dial in rear traction for different track surfaces.

Robust Composite for Racing Durability

Made from a high-tech composite, the XRAY 363123-H balances stiffness and toughness to offer sharp steering response and long life. The tougher construction is aimed at the demands of medium- and high-traction tracks where predictable behaviour is important.

Compatibility and Tuning Options

Designed specifically for the XB4 2020 Specs, this hard arm pairs only with the matching #363113-H hard lower right arm. You can fit the rear shock either in front of or behind the rear shock tower to fine-tune handling to your track.
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.

Will this arm fit older XB4 models?

This part is made for the XB4 2020 Specs and is intended to be used with the matching #363113-H hard lower right arm, so fitment on other model years is not guaranteed.

How does the extra 2mm length change handling?

The added length increases rear traction and straight-line stability, and combined with different shock positions it helps you tune the rear grip balance for low-grip or high-grip tracks.

What track surfaces suit this arm best?

This hard composite arm is aimed at medium- to high-traction surfaces where consistency and precise handling are priorities; on very loose dirt you may prefer a different geometry.
