Performance & Fitment

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

  • Position: Right Front (RF) or Left Rear (LR)

  • Rate: 0.900

  • Diameter: 0.900”

  • Length: 30”

  • Construction: Tubular (Hollow). By removing the dead weight of the center core, this bar allows the suspension to react more rapidly to track ruts and changes in load, keeping the tire contact patch more consistent.

  • Tuning Profile: * As a Left Rear bar: The 0.900" tubular is a staple for "slick" conditions, providing the compliance needed to generate side-bite without being so soft that the car over-rotates.

    • As a Right Front bar: It provides a solid foundation to control front-end roll, helping to maintain aerodynamic wing angle through the corners.

Premium Construction

• • Material: Manufactured from high-strength alloy steel, through-hardened for maximum torsional resilience and fatigue resistance.

  • Precision Manufacturing: Centerless ground to ensure a perfectly consistent outside diameter and wall thickness. This precision is vital for maintaining a repeatable spring rate throughout the bar's life.

  • Heat Treatment: Advanced heat-treating process maximizes "memory" retention, ensuring the bar returns to its original index and resists sagging during long features.

  • Finish: Precision-machined splines ensure a zero-play interface with your torsion arms and stops for immediate chassis feedback.

⚠️ Critical Fitment Exceptions

To ensure safety and performance, verify that your setup does not fall under these common exceptions:

• ❌ Length Verification: This is a 30" tip-to-tip bar. Many standard Sprint Car chassis utilize 29" bars. Ensure your torsion tubes are designed for the 30" length before installation.

• ❌ Rate Comparison: Remember that a 0.900" tubular bar is softer than a 0.900" solid bar. If you are switching construction types, consult a rate chart to ensure you aren't straying too far from your intended wheel rate.

• ❌ Internal Maintenance: Moisture inside hollow bars can cause internal corrosion, leading to stress fractures. It is highly recommended to keep the internal bore clean and lightly oiled to prevent sudden failure.

• ❌ Tube Clearance: Ensure your chassis torsion tubes are straight and free of debris. At 0.900", any internal binding will "lock" the suspension, resulting in erratic handling and potential bar failure.

• ❌ Directional Indexing: Because this bar is indexed for the Right Front or Left Rear, it is critical to install it on the correct side of the car. Installing a directional bar on the "wrong" side will cause it to lose its rate and sag almost immediately.
