SuperTech High Performance Valve Spring Kit, BMW S54

BMW S54 Engines.

Supertech valve springs utilize a superior Superclean Chrome Silicon Vanadium Steel alloy to enhance performance and longevity at high RPMs. By employing this high-grade steel alloy, our valve springs also exhibit improved structural memory.

Our valve springs undergo computer-aided design to ensure that wire stress levels remain within the defined fatigue limits illustrated in the diagrams. Additionally, we utilize advanced computer software to effectively manage harmonics. This, in conjunction with our premium steel alloy, grants Supertech valve springs exceptional durability in extreme conditions. As a result, your performance racing engine gains a significant competitive edge in terms of both performance and endurance.

Supertech retainers are crafted from military-certified Titanium alloy of the highest quality and are meticulously CNC machined to ensure a precise fit. Renowned for their excellence, our retainers rank among the finest in the industry.

 Installation requires the expertise of an engine builder.
