RB26 Shimless Valve Bucket 6.0mm DLC Coated 300M Superalloy

The RBN2JC Valve Bucket is engineered for high-performance and motorsport RB applications where strength, precision, and valvetrain stability are critical. Key Features High-strength 300M material constructionDelivers approximately 50% higher tensile strength than factory buckets for improved durability in high-RPM engines. DLC coated surface finishUltra-smooth micro-polished coating reduces friction, improves wear resistance, and enhances long-term valvetrain reliability. Precision 0.2mm sizing increments (7 sizes available)Allows for highly accurate valve clearance setup and reduces the need for valve grinding. Seamless bucket optimisationDesigned to simplify engine building while improving balance and reducing material removal from valves. Tighter-than-OEM machining tolerancesEnsures consistent fitment and reliable performance in demanding engine builds. High-RPM capable design validationDeveloped for with BODAN test engine operating at  10,500 RPM , with motorsport testing targeting Reliability in Motorsport applications. Motorsport-grade durabilityBuilt for extreme conditions where coating integrity, stability, and repeatable accuracy are essential.
