Purchase VAC - S50b30 Euro High Performance Valve Springs (24 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 that also offers the needed 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 VAC series of 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 from the finest materials and manufacturing techniques; our springs are guaranteed to out perform the competitions valve springs at any price.
