XRAY 351182 Brass Rear Upright 15g Weight for XB Series  [XR-351182]

Tune Rear Stability on Older XB Chassis with XRAY 351182

The 351182 Brass Rear Upright Weight Set is a compact upgrade for vintage XRAY XB Series cars, adding 15g of brass to drop the centre of gravity. This modest weight addition helps stabilise the rear and refines handling without changing your suspension setup. It is a useful option when chasing more predictable corner exits.

Handling Benefits from Rear Upright Weighting

Positioning weight under the rear upright alters the chassis roll behaviour and can reduce rear lift during hard cornering. The result is improved composure through turns and better traction when accelerating out of bends, especially on higher-speed layouts.

Who Should Fit This and How

Made specifically for older XB Series rear uprights, the weight set installs directly and requires only basic tools. It is a quick adjustment for racers and hobbyists who want to experiment with rear bias without major changes to shocks or camber settings.
