 CIRCLE TRACK 1500 SERIES SPRING 
CIRCLE TRACK 1500 Series

The 1500 Series springs were designed from our historical use in Circle Track. These are nitrided springs for use in the
highest endurance applications. Nitriding allows for a durable surface and improved compressive stress. Additional
Nano-Peening and ID and OD chamfering are performed to improve spring life and retainer fitment.
