Valve Spring

Don’t easily fall for the “aggressive-camshafts-give-your- engine- crazy- power, yo!” line that line auto performance wannabe’s blabber about. It’s Camshaft modification is much more complex than that. You have to remember that upgrading your the engine’s camshafts requires modifying the rest of the valve train as well, especially the and this includes valve spring modification.

Why? The logic behind it is simple. Simply because with more aggressive camshaft profiles, V: valve lift greatly increases in more - aggressive camshaft profiles as compared to stock.. With a heavy-duty camshaft, You’ll engine will need stronger, heavy-duty valve springs to pull the valves back down close the valves. , otherwise, you’ll be suffering from valve float metal fatigue can occur when the valve springs and cams aren’t matched equally.

That’s when engine speed doesn’t rev down at high rpm (revolutions per minute).

If you really want more aggressive to equip your car’s engine with high-performance cams, make sure you replace upgrade each valve spring with a high-performance spring as well. This ensures that the valve springs are strong enough to deal with the new cams. Upgrading the valve springs with the cams also reduces the chances of premature valve train damage.

Otherwise, just stick to your stock cams. Highly recommended are titanium, Bee Hive or double-spring designs which are specifically designed for high rpm and racing applications. They’re a lot more stable and can withstand valve float, and won’t run the risk of breaking under extreme engine loads.
