The PROX Steel Valve Kit offers top-quality performance crafted from nitrided steel, which is micro-hardened to significantly reduce friction and wear. This ensures a longer lifespan compared to original valves, making it the optimal replacement for short-lived titanium valves. The kit includes specially weight-adjusted steel valve springs made from chromium-vanadium for exceptionally high resistance to high RPMs. Designed for straightforward installation without modifications to original parts, the PROX Steel Valve Kit caters to those demanding peak performance and durability in their SUZUKI engines.
