Purchase VAC - M10 High Performance Valve Spring Set, 8 pcs

Our VAC High Performance BMW Valve Springs are a dual-spring interference design that is made from H-11 Alloy, a metal often used for highly stressed structural parts (such as aircraft landing gear) that also offers resistance to thermal fatigue so crucial for this use.

Each spring is shot-peened for stress relief and dual-interference fit to control harmonic resonance across the rev range.
In our dual spring configuration, should something happen to one spring, the other can prevent the valve from dropping and causing catastrophic engine damage.

With precise specs and consistent quality, these springs are capable of revving to 11,000+ RPM for added peace of mind and maximum performance. We have been using our VAC series of springs in our World Challenge Touring Car, GT3 car, C-Mod E36 'Silver bullet' and thousands of race and street engines for years with nothing but excellent results.

Designed with the aid of a Formula-1 engineer and the latest technology; our springs are guaranteed to out-perform the competitions valve springs at any price.
