Tomei Oval Wire Valve Springs are specifically designed for used with High Lift Camshafts.

Oval wire valve springs feature greater compression than regular valve springs, allowing them to work with a wider range of 'lift' settings. This makes them compatible with both stock AND aftermarket high lift camshafts.

Using highly durable oval wire allows the valve springs to compress even further whilst still retaining sufficient force. Compatible with many high lift camshafts, these springs provide reliable performance even under load at higher RPMs.
