Performance & Fitment

• • Application: Micro Sprint Race Cars

  • Length: 23”

  • Diameter: 0.680”

  • Tuning Profile: At 0.680", this bar offers a firmer rate than the 0.650"–0.670" options. It is typically used on the "heavy" side of the car to prevent excessive body roll or on high-grip tracks where more resistance is needed to keep the chassis flat.

  • Chassis Compatibility: Standard fitment for most major Micro Sprint manufacturers (such as Hyper, Sawyer, Factor 1, and PMP) utilizing 23" torsion tubes.

Premium Construction

• • Material: Solid high-strength alloy steel specifically formulated for racing applications.

  • Precision Manufacturing: Centerless ground to a precise 0.680" finish, ensuring the spring rate is identical across multiple bars for repeatable tuning.

  • Durability: Engineered with superior "memory" properties to resist sagging or taking a permanent set after heavy suspension cycling.

  • Performance: Precision-machined splines provide a tight, high-clearance fit into 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. It is not compatible with "Short Bar" chassis or larger Midget/Lightning Sprint frames that require 26" or 30" bars. Always measure your torsion tube length before purchase.

• ❌ Misaligned or Damaged Tubes: Because this bar is ground to exacting tolerances, any bend or debris inside the chassis torsion tube will cause the bar to bind. A binding bar will not provide the advertised spring rate and can cause unpredictable handling.

• ❌ Non-Standard Splines: Ensure your torsion arms and stops are designed for the standard spline count used on 23" Micro Sprint bars. Using mismatched components will lead to stripped splines and potential suspension failure.
