Inside your engine the valves control the flow of air in and out of the cylinder head. Your camshaft forces the valves open, but it is the job of your Nissan Silvia valve springs to slam the valves shut. Worn out valve springs can cause poor running conditions especially at high rpm, and if a valve spring should break it could cause total engine failure. Don't risk running tired old Nissan Silvia valve springs. Here at Andy's Auto Sport we have a full selection of replacement Nissan Silvia valve springs that will rejuvenate your motor and keep you running strong for years to come. With springs from all of the top brands in the full price spectrum, you are guaranteed to find the perfect valve springs for your ride in our expansive lineup.

In the high-tech world of Formula One racing, the cars rely on compressed air to quickly shut the valves. However this setup is much too complex and pricey for normal motorsports, let alone street driven machines. But there are still better alternatives to OEM valve springs. Aftermarket Nissan Silvia valve springs are available in higher spring rates that will provide quicker shutting speeds to enable you to rev your motor higher. Some of these kits are setup for dual valve springs to give you the ultimate in valve train performance. If you have added a high-lift cam to your vehicle or plan on running your motor high in the rpm range, we strongly recommend a set of uprated valve springs.

Q: What are valve springs? Why buy them?
A: Valve springs are used in conjunction with retainers in order to take the impact of running high RPMs. When purchasing camshafts or looking to increase the revs of your motor, a set of valve springs and retainers should be purchased. Single and double wound valve springs are designed for high stress and have a high resistance to vibrational contact and harmonic wear from the motor.
