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″.



  • Free Length Range: 6.625″ to 7″
  • Spring Rates: 700#/in to 1225#/in
  • Material: High tensile chrome silicone
  • Finish: Hyperco dark blue powder coat


  • Circle Track Racing
  • Dirt Modified Racing
  • Limit the axle rotation on acceleration, which helps increase grip
