For the 01 F150 Xcab, is there sway bars either front or rear from the factory? If not, which end should I do first for the best results, front or rear? I get the feeling that the rear needs it most.

 

It comes with a front one; aftermarket front ones are larger, stronger, and have better end links and bushings. There is no rear one from the factory. The best thing you can do is installed a matching front and rear aftermarket set. They are engineered to compliment each other to obtain optimal handling characteristics.

 

he said it all, if your tight on money go for the rear first, but you might end up saving money in the long run if you buy them together. you might get a better deal
