improves cornering and handling stiffness on my stock 2014 Grand Cherokee Limited. The trade-off is a harsher experience on the road, especially over small bumps and potholes. On the track, the vibrations are amplified and there's a lot more feedback from the steering wheel. I replaced all four shocks at once and adjusted the front end to the first notch up and raised it 0.75" per the included instructions. The stance is right, without as much nose nodding, but I feel like it reduced my gas mileage and efficiency.
