With a parallel bar 4link you basically have up and down movement of the suspension which is fine for mild street use...ideally for high hp as a starting point you would want your lower bar level and your upper bar at a slight decline going towards the front..if you can imagine both bars extending beyond the front of the truck you would want them to imaginarilly intersect about 3-4 feet ahead of the front bumper..this is the way a drag car is initially setup...if that intersection point was shorter (say that point intersected at the front wheel) your weight transfer is shorter meaning it will pull the front end up faster as weight transfers to the rear...if you extended that point to say 10 ft ahead of the bumper you would have less weight transferring to the rear meaning it wouldn't have as much weight transfer to the rear for traction...so shorter is more leverage and longer is less leverage..with a adjustable 4 link you can fine tune this weight transfer for ideal traction..to much weight transfer is wasted energy and not enough weight transfer is lost energy
Confused yet?
