Upper Shock Tower Bar Kit for BMW G22, G23, G26 430i and M440i
Unlock sharper front-end response and confidence-inspiring control with this Dinan upper tower bar set for the latest BMW 4 Series. Engineered to tie the strut tops together for a more rigid front clip, this upgrade delivers crisper turn-in, improved steering accuracy and a planted feel through rapid direction changes. If you want a tighter, more connected drive on road or spirited B-road blasts, this chassis reinforcement is a brilliant addition.
Precision CNC machined from solid billet aluminium and finished in stealth black anodised, the bars look as good as they perform. The kit is a direct-fit, bolt-on solution that utilises factory mounting points for a hassle-free install and an OEM-plus finish in the engine bay.

Built to perform, built to last
These upper braces replace the flimsy factory cross tubes with stout, black anodised billet aluminium pieces that resist deflection. The result is a stiffer structure across the shock towers and a noticeable upgrade in real-world drivability. We have fitted this kit to our own cars and for customers, and feedback has been consistently positive on both the driving feel and the OEM-plus aesthetic.
Installation and fitting
Simple, reversible bolt-on installation using factory hardware locations. No coding required.
