Performance & Fitment

• • Application: Sprint Car (Winged or Non-Wing)

  • Length: 29”

  • Diameter: 1.000”

  • Type: Tubular (Hollow). By removing the dead weight of a solid core, this bar offers the massive spring rate of a 1-inch diameter while allowing the suspension to cycle faster and maintain better tire-to-track contact.

  • Rate: 1.000

  • Non-Prestressed: This bar has not been pre-twisted in a specific direction. This makes it omni-directional, allowing it to be used on either the Left Rear or Right Rear position. It provides a more natural, predictable "break-in" for tuners who want a bar that isn't "pre-loaded" toward one side.

  • Tuning Profile: A 1.000" tubular bar is a heavy-duty tuning tool. It is typically used on the Right Rear for high-speed, high-bite tracks to keep the chassis from bottoming out, or as a "stump-puller" Left Rear bar for non-wing cars needing maximum hike control.

Premium Construction

• • Material: Manufactured from high-strength alloy steel, heat-treated to ensure maximum torsional resilience and a long fatigue life.

  • Precision Manufacturing: Centerless ground to a strict 1.000" tolerance. This level of precision is vital for a tubular bar to ensure uniform wall thickness and a consistent spring rate.

  • Finish: Coated with a durable powder finish to protect against the abrasive impacts of track debris and corrosive dirt chemicals.

  • Spline Integrity: Precision-machined splines ensure a tight, no-slop fit with torsion arms and stops, providing immediate suspension feedback.

⚠️ Critical Fitment Exceptions

A 1.000" tubular bar requires specific maintenance and setup considerations:

• ❌ Natural "Set" and Break-In: Because this bar is non-prestressed, it is susceptible to "taking a set" (dropping slightly in ride height) after its initial heat cycles. You must monitor your chassis heights closely during hot laps and the first heat race to re-adjust your torsion stops.

• ❌ Internal Bore Care: Tubular bars are hollow; moisture trapped inside can lead to internal rust and stress fractures. To prevent sudden failure, keep the internal bore clean and lightly lubricated or use end caps.

• ❌ Critical Tube Clearance: A 1.000" bar occupies nearly all the space inside a standard torsion tube. Your chassis tubes must be perfectly straight and free of any debris. Any internal binding will "lock" the suspension, leading to a dangerously erratic or "skating" car.

• ❌ Shock Valving: The rebound snap of a 1.000" rate is significant. Ensure your shocks are valved with enough rebound control to prevent the car from "pogoing" or bouncing after hitting a rut.

• ❌ Length Check: This is a 29" tip-to-tip bar. Verify your chassis requirements, as some newer-style Sprint Cars or Modifieds utilize 30" or 31" bars.
