The springs that close the valves on every engine revolution.

PROX offers this valve spring kit intake for SUZUKI RM-Z 450, RM-Z 450 E, RMX 450 Z from 2005 to 2026. The camshaft opens the valves and the springs close them. At high revs the spring must bring the valve back very quickly: if it is tired, the valve can no longer keep up and “floats”.

Why replace the valve springs?

The benefits:

Safe running at high revs again.
Essential with a hotter camshaft or steel valves, which are heavier than titanium.
Quality steel springs keep their strength longer.

Why choose PROX?

ProX, the Dutch engine-parts specialist since 1975, has its parts made in factories that also supply the manufacturers: OEM quality at a more affordable price.

When should you replace the valve springs on your SUZUKI RM-Z 450?

Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
