Ok, I'm going to order some Bilstein shocks for my truck tomorrow. I'm getting all four. I've read that some people get shocks for crew cabs to get a bit firmer ride. Is this needed, or will extended cab shocks be fine? My truck is all stock, and I drive it everyday I'm not on my Harley. I'm pretty sure the factory drop is 1" in front and 2" in the rear, is that correct?? I've also read about rear bracket extenders, I don't have them and would prefer not to if possible. Does anyone know the Bilstein part numbers im looking for??
