Tundra Product Notes

DR-4 Pearl

The new DR-4 Pearl cover will offer the most length in the Track line. This cover is the perfect option for those super dry conditions. 

Track Symmetric

The Track Symmetric core is a super high rg, low differential core that will be a must in any tournament bowlers bag. A core with unique numbers like this will allow the core to store energy longer while remaining smooth and controllable down lane. 

Track Tundra

When the lanes are on fire, put them on ice by pulling out the new Track Tundra. This core/cover combination will provide ultimate control when you need it most. Whether you are bowling on old wood lanes, lighter volume oil patterns or on lanes that just flat out hook, the Tundra is the ideal ball for you.
