Rear sway bar
I have an 04 Desert Runner and originally bought an aftermarket rear bar and couldn't stand it. I went to the local dealer and bought the Nissan part for an Xterra. Came with the links included and bolts on with no modification whatsoever. The handling difference is astounding. With the bigger aftermarket sway bars my truck felt like it was pushing into curves, with the factory part it makes you feel like your driving a sports car. I kid you not. With a set of Monroe Reflex shocks and the rear sway bar installed it feels as stable as any car you have driven. Oh yeah, I think I paid less than $130.00 for everything and it took about thirty minutes to install.
