QuickChange Torsion Bars are Plated & Plugged and include a female threaded end that you can engage with a bolt to use as a handle for easier extraction / insertion.
Use the rears bars in combination with our QuickChange™ Spring Plate products for fast torsion bar swapping and re-indexing. QuickChange™ Torsion Bars can be extracted through the QuickChange™ Spring Plate without removing any bolts. Alignment settings are maintained. You don't even need to remove the wheel from the car. Changing torsion bars is a 5 minute per side operation!
A QuickChange™ Insert is available separately for converting your existing hollow torsion bars.
QuickChange™ Torsion Bars make it easy to dislodge a stuck bar, and thereby offer benefits even when used on the front and with factory spring plates (factory spring do not allow the bars to be extracted without removing the plates).

Our Plated & Plugged Hollow torsion bars are the best available. The ends are plugged to prevent moisture entry that rots ordinary hollow bars from the inside out. The entire bar is zinc plated for superior protection.
Excellent quality control means proper spline fit and spring-rate consistency bar-to-bar. Inferior quality competing bars fail on all counts.
• Hollow, light weight
• Plated & Plugged
• Consistent spring rate
• Great spline fit
Upgrade Hollow bars provide a nice weight savings over equivalent spring rate solid bars, especially true of the heavier rear bars. This is a great way to trim extra pounds from the back of your car.
* The size given is a solid-bar-equivalent. Actual hollow bar measures about. 5mm larger.
