Known consequence. I have not heard of any spring kits that maintain or improve the ride. Everyone that has lowered their ML says the same thing.......harsh ride.

You could spend about $5,000 for an air suspension. There are only a couple in the U.S. that have done this.

You could put the OEM springs and shocks back, and get oversized rims and tires to fill in the fender and install H&R sway bars to help with the body roll.

The ML is a 4 wheel drive truck. If you really want a sporty ride SUV get the Infiniti
