The Tamiya 3454921 Blue Upper Bulkhead is a precision-machined aluminium part for the TRF418 chassis. Its anodised finish gives a race-ready look while adding upper-chassis stiffness for sharper reactions at speed.
Aluminium construction adds durability and helps keep suspension geometry stable under load. The result is more consistent handling and improved feedback when pushing the car hard.
Whether you are trimming setup for qualifying or race distance, this blue upper bulkhead helps you maintain predictable balance and improves front-end feel through technical sections.
