Performance & Fitment

• • Application: Micro Sprint Race Cars

  • Length: 23”

  • Diameter: 0.710”

  • Tuning Profile: At 0.710", this bar sits at the top end of the standard stiffness range. It is primarily used to prevent chassis "bottoming" and to provide aggressive weight transfer control in the Right Rear or to stiffen the front end on high-speed ovals.

  • Chassis Compatibility: Fits standard Micro Sprint chassis (Hyper, Sawyer, Factor 1, PMP, etc.) utilizing a 23" torsion tube.

Premium Construction

• • Material: Solid high-strength alloy steel specifically selected for high-stress racing environments.

  • Precision Manufacturing: Centerless ground to a precise 0.710" diameter to ensure a perfectly linear spring rate and uniform performance across the entire torsion arc.

  • Heat Treatment: Through-hardened to optimize "torsional memory," ensuring the bar maintains its rate and ride height over a full season of racing.

  • Splines: Precision-machined ends for a secure, 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 designed for "Short Bar" setups (19" or 21") or larger Midget/Lightning Sprint frames that require 26" or 30" bars.

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

• ❌ Component Wear: Ensure your torsion arms and stops are in good condition. The high torque generated by a 0.710" bar will quickly strip worn or low-quality splines, leading to a total loss of suspension control.
