Swiftune Road Valve Spring Bundles - Steel

We offer a kit with Swiftune race double valve springs. We recommend them with high lift cams including the SW5 and SW10.

Fitted at 1.380" these springs give 80lb seat pressure and 180lb pressure at 0.500" lift.

In this kit, you will find a set of steel top cap and collets. Both suit single groove race valves 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.

This set includes:

• 8 x Swiftune road valve springs
• 8 x Swiftune steel top caps
• 8 x Swiftune race valve spring washers
• 16 x Swiftune race single groove collets
