CSI 1 1/8 x 30" Hollow Sprint Torsion Bar

We are proud to officially announce the launch of our new line of premium torsion bars — manufactured by DMI and available exclusively through CSI.

This isn’t just another bar added to the catalog.

This is a strategic partnership between CSI and DMI to deliver what we believe is the highest quality American-made torsion bar on the market today.

DMI is known throughout the motorsports industry for precision, durability, and uncompromising manufacturing standards. By partnering directly with DMI, we’ve ensured:

• Superior material quality
• Tighter tolerance control
• Unmatched straightness and consistency
• Repeatable rate accuracy bar-to-bar

You won’t find a straighter, more consistent torsion bar — period.

Every CSI torsion bar is:

• American Made
• Precision machined
• Threaded for a retainer
• Manufactured to exacting standards
