Why You Need This Kit:
The factory stamped steel torque boxes are known to flex under load – especially in high-power, track, or drag applications. The Next Gen Performance Center Adjustable Lower Torque Box Kit eliminates that deflection, giving you consistent rear suspension behavior when it counts.
This kit features 5 adjustment holes, allowing you to fine-tune your suspension geometry for more or less rear bite, depending on your setup. Whether you're dialing in for street, strip, or a lowered stance, this kit helps maintain your instant center and anti-squat numbers without compromise.
Pair this with rear end relocation brackets for the ultimate in rear suspension tuning. Whether you're launching hard at the track or carving corners, you’ll feel the difference in control, grip, and predictability.
