Outlaw Racing OR5258-EK Exhaust Valve and Spring Kit KTM 450EXC 520SX 525SX. These Stainless steel valve kits are designed to replace whole valve assemblies for less than the cost of OEM valves, while improving overall durability over stock. Manufactured in ISO 9001 certified factories, these Nitride coated components improve heat transfer and carbon build up for increased valve train life. The forged, one-piece construction design helps weight reduction as well as improved flow. The valve springs are made from oil tempered steel wire (SWOSC-V) and the seats and retainers are made from 4041 steel and 7075 T-6 aluminum for some applications.
