Brian Crower Intake / Exhaust 31.15mm Lifter Buckets W/DLC Coating - Polaris XP1000 / XPTurbo

Features DLC (Diamond Like Carbon) surface treatment for improved wear characteristics. Made from aerospace grade, 4140 chromoly steel alloy and completely CNC machined from heat-treated billet round bar. Heavy-duty wall thickness eliminates distortion and cam face depression, while reducing overall weight from non-critical stress areas. Nitrided and polished to a surface hardness of 60RC for minimal wear. Provides lower friction with cam lobes and cylinder head lifter bores for improved durability.
