Performance & Fitment

• • Application: Micro Sprint Race Cars

  • Length: 23”

  • Diameter: 0.740”

  • Tuning Profile: The 0.740" bar is an extreme-rate component. It is specifically used for high-grip, high-banked "cow pasture" tracks or high-horsepower Winged Micro applications where preventing the chassis from rolling over on the Right Rear is the top priority for maintaining traction.

  • Chassis Compatibility: Standard fitment for Micro Sprint chassis (Hyper, Sawyer, Factor 1, PMP, etc.) utilizing 23" torsion tubes.

Premium Construction

• • Material: Solid high-strength alloy steel for maximum durability and superior torsional resilience.

  • Precision Manufacturing: Centerless ground to a precise 0.740" diameter, ensuring an exact, repeatable spring rate that remains consistent night after night.

  • Heat Treatment: Through-hardened to optimize "memory" retention, preventing the bar from sagging even under the massive loads generated by its heavy spring rate.

  • Splines: Precision-machined ends ensure a high-tolerance, zero-play fit with torsion arms and stops.

⚠️ Critical Fitment Exceptions

Even if you are racing a Micro Sprint, ensure your setup does not fall under these exceptions:

• ❌ Incorrect Tube Length: This bar is exactly 23" long tip-to-tip. It will not fit chassis specifically designed for "short" bars (19"–21") or larger Midget/Lightning Sprints that require 26" or 30" bars.

• ❌ Internal Tube Binding: Because this bar is ground to exact tolerances, any internal rust, debris, or structural bends in the chassis torsion tube will cause binding. A binding bar creates an effectively "infinite" spring rate, leading to unpredictable and dangerous handling.

• ❌ Hardware Stress: The extreme torque loads generated by a 0.740" bar require torsion arms and stops to be in pristine condition. Ensure your hardware matches the standard spline count; using worn or low-quality components with a bar this stiff significantly increases the risk of stripping splines during high-load cornering.
