Specs At A Glance

Good To Know

Q: Will these helper springs make my ride stiffer when unloaded? A: They engage mainly when the suspension compresses under load; during empty driving, you’ll notice only a minimal increase in firmness without the jarring ride of metal add-a-leafs.

Q: Do I need to disassemble the factory leaf springs to install? A: No, the bracket clamps around the leaf pack and axle; installation takes about an hour with basic hand tools and no spring disassembly required.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
