Performance & Fitment

• • Application: Sprint Car (Winged or Non-Wing)

  • Length: 29”

  • Diameter: 1.050”

  • Type: Tubular (Hollow). By utilizing a large-diameter hollow design, this bar achieves an extreme spring rate with significantly less weight than a solid bar, improving the suspension's "rebound speed" and tire contact.

  • Rate: 1.050

  • Non-Prestressed: This bar is omni-directional. Because it has not been pre-twisted during manufacturing, it can be used for either Left Rear or Right Rear positions. This allows for a more natural break-in and a predictable, stable handling profile.

  • Tuning Profile: The 1.050" tubular bar is an aggressive tuning tool. It is typically utilized on the Right Rear for high-speed half-miles or extremely "hooked-up" tracks where massive centrifugal forces require maximum platform support.

Premium Construction

• • Material: Manufactured from high-strength alloy steel, heat-treated for maximum durability and resistance to torsional fatigue.

  • Precision Manufacturing: Centerless ground to a strict 1.050" tolerance. This ensures uniform wall thickness across the tubular span, resulting in a perfectly consistent and repeatable spring rate.

  • Heat Treatment: Advanced through-hardening optimizes the steel's "memory," helping the bar maintain its index and resist sagging over time.

  • Finish: Precision-machined splines provide a zero-play interface with torsion arms and stops, ensuring immediate suspension response.

⚠️ Critical Fitment Exceptions

A bar of this diameter and rate requires precise maintenance and chassis prep:

• ❌ Ride Height Monitoring: As a non-prestressed bar, it is prone to "taking a set" (settling) during its first several heat cycles. Closely monitor your ride heights and block measurements during the initial night of racing and adjust your torsion stops accordingly.

• ❌ Internal Bore Maintenance: Hollow bars are susceptible to internal rust from trapped moisture, which can lead to sudden stress fractures. Keep the internal bore clean and lightly oiled or use protective end caps.

• ❌ Critical Tube Clearance: At 1.050", this bar is at the upper limit of what standard torsion tubes can accommodate. Your chassis tubes must be perfectly straight and free of any mud or debris. Any internal binding will "lock" the suspension, causing the car to bounce or skate uncontrollably.

• ❌ Rebound Damping: The 1.050" rate has a very high "snap" or return frequency. You must ensure your shock valving (specifically rebound) is heavy enough to control this bar, otherwise, the car will "pogo" off the corners.

• ❌ Length Check: This is a 29" tip-to-tip bar. Verify your chassis requirements, as some newer-style Sprint Cars require 30" or 31" bars.

• ❌ Hardware Integrity: The torque generated by a 1.050" bar is immense. Inspect your torsion arms for "egging" or spline wear; worn hardware will likely shear under the loads this bar exerts on the chassis.
