Performance & Fitment

• • Application: Dirt Modified Race Cars

  • Position: Right Rear (RR)

  • Rate: 0.925

  • Diameter: 0.925"

  • Length: 29”

  • Tuning Profile: The 0.925" rate is a stiffening option for the Right Rear. It is ideal for heavy track conditions where a softer bar would allow the car to "over-roll," causing the chassis to bottom out or lose drive. This bar keeps the RR platform stable, ensuring maximum power delivery to the ground.

Premium Construction

• • Material: Manufactured from solid high-strength alloy steel for superior torsional resilience and long-term durability.

  • Precision Manufacturing: Centerless ground to a strict 0.925" diameter. This ensures a perfectly consistent spring rate, allowing you to make predictable setup changes at the track.

  • Heat Treatment: Through-hardened and pre-stressed to optimize "memory" retention. This process prevents the bar from sagging or "taking a set" even after high-stress racing cycles.

  • Spline Finish: Precision-machined splines ensure a tight, no-slop interface with your torsion arms and stops, providing immediate suspension response.

⚠️ Critical Fitment Exceptions

Before installation, verify that your setup does not fall under these common exceptions:

• ❌ Chassis Length Check: This is a 29" tip-to-tip bar. It is designed for standard Dirt Modified chassis and will not fit Sprint Cars or Mini Sprints that utilize 26" or 30"+ bars.

• ❌ Position Specificity: While this bar is 29", a 0.925 rate is a specific tuning choice. If you are replacing a softer bar (e.g., a .900), ensure your shock valving can handle the increased spring frequency to avoid a "skating" sensation on corner exit.

• ❌ Tube Clearance: Ensure your chassis torsion tubes are perfectly straight and free of internal debris. At 0.925", the clearance is reduced; any internal binding will "lock" the suspension and lead to erratic handling.

• ❌ Spline Wear: Never install a new bar into worn or "egged out" torsion arms. High-torque loads on the RR will quickly strip damaged splines, leading to a catastrophic failure mid-race.

• ❌ Indexing: Always check the bar for "twist" after a heavy impact. A bar that has been over-torqued will lose its original index, making it impossible to accurately set your corner weights.
