How much does this kit lower the rear of my truck?

This Belltech kit is designed to provide a 4-inch drop in the rear suspension. This is achieved by repositioning the leaf spring mounting points.

Do I need to modify my factory leaf springs with this kit?

No, the primary benefit of this shackle and hanger kit is that it allows you to lower your truck without modifying or changing your factory leaf springs. This helps retain your original ride quality and load capacity.

What is involved in the installation process?

The hangers and shackles are designed to be a bolt-in replacement for your stock mounts. However, you will need to drill or grind out the original riveted-on hangers before installing the new components.
