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.

• Precision relay of cam profile characteristics with the valve train
• Reliable under load at high rpm
• High natural frequency to prevent surging
• Durable
• Lightweight

Most high performance KA24DE valve springs tend to employ a dual spring design. However, the additional weight and increased friction resistance can often to lead to significant stress on the rest of the valve train.
