The camshafts also feature a revised profile that allows for improved valve control and reduced valve float, resulting in smoother and more consistent engine operation.
The Kelford R-199-D Camshafts are made from high-quality materials, including a heat-treated steel alloy, and are precision-machined to ensure a perfect fit in your Subaru engine.
