Rear bias upgrade for XRAY XB4 using XRAY 361191

The XRAY 361191 Brass Rear Chassis Brace Weight is a precision brass upgrade made to improve the handling of your XRAY XB4. This 40g brass component mounts into the lower section of the composite brace and attaches to the chassis to move mass rearward, lowering the centre of gravity and enhancing rotation for steadier cornering at speed.

Improved rotation and chassis balance

CNC-machined from solid brass for consistent tolerances, this weight guarantees a snug fit and repeatable behaviour. Placed at the rear it helps tune chassis flex and balance, which is important when dialing in handling for carpet or hard-packed surfaces. Use it as part of a wider setup tweak to gain better mid-corner rotation and stability.

Weight: 40g

A practical upgrade for racers aiming to refine rear-end feel and cornering behaviour on an XB4 chassis.

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.

How will the 40g brass weight change handling?

Adding the brass weight shifts the centre of gravity lower and toward the rear, which increases rotation and helps stabilise the car through high speed corners. It is a tuning tool rather than a cure-all and works best combined with spring and shock adjustments.

Does this fit all XB4 variants?

Yes, the part is designed to be compatible with XRAY XB4 Series models from 2016 through 2021 and installs into the lower composite brace as shown in the parts diagram.

Is special tooling required to install it?

Installation is straightforward with basic hand tools. Tighten fasteners to the recommended torque and check for interference with nearby components after fitting.
