With the F-53 chassis there's a "cheap fix" for that top heavy feeling. All you need to do is move the bolts for the existing factory swaybar closer to the axle. The factory position has the bolts in the outer holes. Moving them closer to the axle does wonders to minimize the lean present in the stock arrangement. However, because it puts a bigger strain on the stock swaybar, the original bushings will fail shortly after the change. You'll need to replace the original bushing with polyurethane bushings so they'll last. These changes will the least expensive and most effective ones you'll ever make to your chassis.
