Prox Steel Exhaust valveRef : PRO00671A / 1004678

PROX Steel Exhaust Valve designed for Suzuki DR-Z400 (E / S / SM) and KLR400R engines. This steel exhaust valve is aimed at riders and mechanics looking for a robust replacement part for the cylinder head, suitable for both road and off-road use.

Replacing a worn exhaust valve restores the seal at the seat, ensures clean combustion, and preserves the longevity of your engine. The steel design offers the necessary resistance to thermal cycles and stresses encountered on trails, roadsters, or quads without promising unverified effects on power.
