Review on Enhance Your Ride with Air Lift 1000 Air Suspension Kit 80754: Experience Unparalleled Comfort and Control by Roel Lebron

I use these air boxes in the rear coil springs of my front wheel drive car. It might sound a little crazy, but these pads neutralize weight transfer to the rear of the car by keeping the front wheels in place. An added benefit is that the axles stay more parallel to the road, which means much less torque. They aren't bouncy at 35psi (of course it depends on the car) - there's almost no rebound so I ride them aired every day and I love it. With a simple valve stem to bleed and fill, it's a great return on investment for the cost and hassle of swapping out stiff rear springs for the track.
