XRAY 351182 Rear Upright Brass Weight Kit for Vintage XB Series  [XR-351182]

Stability Upgrade for Older XB Series with XRAY 351182

For enthusiasts of the XRAY Vintage XB Series, the 351182 Brass Rear Upright Weight Set is a straightforward upgrade to increase rear-end stability. Made from solid brass, the kit adds 15g to lower the center of gravity on older XB chassis. This tweak helps reduce body roll and gives a more planted feel whether you are racing or running around the track for fun.

How the 15g Brass Affects Handling

Placing the brass weight under the rear upright influences weight distribution and can tame excessive rear lift. The lower center of gravity improves mid-corner balance and reduces unsettled behaviour on fast direction changes. Use this when you need a predictable increase in rear traction without changing suspension geometry.

Fitment Notes and Quick Install

This set is made specifically for older XB Series variants and fits those rear uprights directly. Installation is simple and typically requires basic hand tools to secure the weight under the upright. The add-on is reversible, so you can test different setups without permanently altering the car.
