Pull Bar Springs

Pull Bar Springs are primarily used in Circle Track racing, especially Dirt Modified racing. The 5” OD size allows for the spring to be used alone or with spring rubbers (urethane donuts). This allows for optimization of the total vehicle performance package on many Circle Track vehicles.

Key Benefits of Pull Bar Springs

More usable deflection
Less weight
2% rate linearity tolerance from 20% to 60% of deflection
6% rate linearity tolerance from 61% to 80% of deflection
Designed to fit all standard hardware
Maintain free length and rate throughout a near infinite operational life

NOTE: Generally, the higher the spring rate, the lower the total deflection. However, the majority of pull bar springs will deflect between 2.125″ and 2.75″.
