Heavy Duty Std Diameter Exhaust Valve Set, Polaris 2011- RZR 900XP/ XP4

Description The Sparks Racing HD Standard Diameter Exhaust Valve Set for the RZR 900 XP/XP4 will replace all of the exhaust valves with stainless steel valves which have been coated in a friction reducing coating, which eliminates the excessive valve guide wear seen with stock valves and guides. If this upgrade is made early enough in the engine’s life, you can avoid the costly repairs needed when the valve guide are worn. A precision valve job is recommended anytime new valves are installed in a used head.   Each Kit Includes: (4) HD Standard Diameter Exhaust valves       SKU: VLVP11900XPEXS
