New from Smokem are new split lower bulkheads for the Xpress XQ1. Offering vastly improved flex characteristics, they allow the car to generate improved grip and widen the chassis' tuning window.

The design also uses flanged bearings for mounting the sway bars to the bulkheads. This allows the bearings to be inserted from the centre of the car for easier installation and smoother operation.

The bulkheads are available as a complete set of 4 with 4 bearings included to suit both the standard XQ1 and mid-pulley converted XQ1.
