We offer a kit with Swiftune race double valve springs. We recommend them with the Swiftune SW23T billet race camshaft. These race springs are fitted to all our race engines.
In his kit, you will find a set of Swiftune top cap super light. Manufactured from incredibly strong steel to enable machining to a much thinner section making these the lightest yet strongest steel top caps on the market. You will also find a set of race collets. Both sets are suitable for single groove valve only.
We will also supply a set of washers to sit beneath the Swiftune race valve springs. These are used to perfect the fitted spring length and tension on high performance engines.
