Upgrade and maintain your valvetrain with KPMI OEM replacement valve retainers, engineered specifically for Harley-Davidson Shovelhead 80" engines from 1978 to 1983. Crafted from U.S. mill-certified steel bar, each retainer is designed using advanced Finite Element Analysis (FEA) software to optimize weight reduction without sacrificing essential structural strength.
These heat-treated steel retainers undergo a proprietary treatment process that creates a wear-resistant hard outer shell while preserving a tough, non-brittle core.
