Performance & Fitment

• • Application: Micro Sprint Race Cars

  • Length: 23”

  • Diameter: 0.670”

  • Tuning Profile: The .670" diameter is a common "step-up" bar, offering increased stiffness over smaller diameters to help the car "set" faster in the corners and handle higher bite track conditions.

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

Premium Construction

• • Material: Solid high-strength alloy steel for maximum durability and fatigue resistance.

  • Precision Manufacturing: Centerless ground to ensure a perfectly uniform outside diameter and a highly consistent spring rate.

  • Heat Treatment: Heat-treated to enhance "memory," ensuring the bar returns to its original position without sagging after heavy loading.

  • Performance: Engineered to withstand the high-frequency oscillations and jarring impacts typical of circle track racing.

⚠️ 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 designed for "Short Bars" (e.g., some 19" or 21" setups) or larger Midget/Lightning Sprint chassis that may utilize 26" or 30" bars.

• ❌ Damaged Torsion Tubes: This bar is centerless ground to precise tolerances. If your torsion tube is bent or has internal burrs from a crash, the bar will bind. The bar must be able to rotate freely within the tube to provide the correct spring rate.

• ❌ Spline Mismatch: While standard in the industry, always verify that your torsion arms and stops are compatible with the spline count on this 23" bar to avoid stripping the teeth under high torque. 

What’s Included
