Kelfords new 35mm DLC Coated Valve Adjustment Buckets allow for precise adjustment of your EJ20 and EJ25 engine's valve lash. Featuring a DLC coating and machined for increased strength and rigidity, these buckets are the perfect addition to keep your Subaru running great. We've thoroughly tested these on our Spintron to ensure the quality of the parts with over 450 hours of continuous run time. These buckets are sold individually, so please select the quantity of each required for your application.

The Kelford 35mm Buckets are coated with Diamond Like Coating. (DLC) DLC is a surface-finishing process that reduces friction, lowers oil temperatures and increases both camshaft and bucket longevity. DLC coating is particularly useful for engine components that rely on splash lubrication, like buckets, because it helps prevent damage to surfaces in case of inadequate lubrication.

Each Kelford 35mm DLC Coated Bucket is precisely machined and graded in .03mm increments, allowing precise adjustment of the valve lash. The buckets also feature a larger internal fillet and a reinforced skirt for strength. The geometry is designed around the OEM tip height meaning these followers can be used with OEM valves, or aftermarket valves using OEM geometry.

Professional installation is recommended. The bucket selection process involves precise measurement to ensure the appropriate valve lash is achieved for your application. Calculations must be performed to ensure success. Please double check all measurements before ordering. These buckets may not be returned once installed.
