With the help of Supertech valve springs & titanium valve spring retainers, higher RPM's can be run. It also eliminates valve flutter at high RPM's. At high RPM's, the rocker arms can break and the valve springs can jam. This can lead to engine damage! The Supertech valve springs have an extra adjusted spring rate.
Advantages:
- The valve train becomes lighter thanks to the titanium valve spring retainers
- The motor revs up faster
- Higher motor RPM's can be run
- The valve train becomes more stable during power increases
Likewise, we offer the full range of Supertech:
Valve keepers, mechanical tappets (rigid tappets) with matching shims and forged pistons.
