RAS is perfect for the track! The design and setup push down on top of the axle instead of pulling from the bottom. This allows for a more consistent pressure to be applied and helps to keep the leaf springs from bouncing when launching off the line. And with the way it mounts, it keeps the axle from rotating up while under acceleration. I have yet to get any wheel hop when using them, regardless of street tires or drag radials. They helped me set a new world record, and helped me get a 1.58 60’. I’m now the only steel body ecoboost in the 11s and the only one with a 1.5 60’. Thank y’all for making such a great product. I daily drive my truck, and from time to time I have to haul stuff. I have had my truck loaded down the same ride height even while loaded down with heavy furniture and appliances. I’ve even carried a 55 gallon drum of fuel in the back and it barely squatted.  It also helps to stabilize the suspension when going around curves. Since installing I’ve notice I have very little body roll or swaying when cornering. - Steven S.
