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 still offers resistance to thermal fatigue.
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 12,000 RPM for added peace of mind and
maximum performance. We have been using our springs in our World
Challenge Touring Car, GT3 car, C-Mod E36 'Silver bullet',
thousands of race engines, and street engines for years with
nothing but excellent results.
Designed with the aid of a Formula-1 engineer; these springs are
guaranteed to out perform the competitions valve springs at any
price.
