Performance & Fitment

• • Application: Micro Sprint Race Cars

  • Length: 23”

  • Diameter: 0.720”

  • Tuning Profile: As one of the stiffest bars available in the 23" standard length, the 0.720" is an "extreme-rate" bar. It is primarily used to control aggressive weight transfer on the Right Rear or to prevent front-end "diving" on high-speed, high-banked ovals with significant grip.

  • 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 torsional resilience.

  • Precision Manufacturing: Centerless ground to a precise 0.720" diameter to ensure an exact and repeatable spring rate.

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

  • Finish: Precision-machined splines ensure a tight, secure interface with torsion arms and stops to prevent stripping.

⚠️ 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. It will not fit chassis specifically designed for "short" bars (19"–21") or larger Midget/Lightning Sprints that require 26" or 30" bars.

• ❌ Tube Internal 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 prevents the suspension from cycling and can lead to erratic handling.

• ❌ Component Wear & Spline Mismatch: The high torque loads of a 0.720" bar require torsion arms and stops in perfect condition. Ensure your hardware matches the standard spline count; using worn components with a bar this stiff will likely result in stripped splines during high-load cornering.
