Thanks for reply - actually I took the car to the Nissan dealership (bad idea) for the 65K check up. During the day, they called me and said that I needed to replace my Shocks/Springs - I declined to get it through them. I didn't tell them anything about my motorcycle situation.

Few months back at a motorcycle event. Another racer with an '04 Xterra, saw my setup and recommended that I get stiffer leafsprings to lessen the abuse on the rear suspension. I never gave it much thought until I got the news from the dealer.

I don't do any off roading (I wish I did, I live in NY) Other than driving around the neighborhood, I basically use my truck for motorcycle racing and snowboarding and that's it. If figured if I was in the market for suspension, then I would get something other than stock products.

Also when I transport my bike, I usually fill the back cargo section with tons of crap, like Tools, extra set of rims, camping gear and etc. I just want my truck to last.

I hope I didn't confuse you. I appreciate your help.
