I got this truck used last year and it seem to sag just a bit in the rear and when I put even a 250lb dirt bike in the rear it sags a bit much and makes it drive poorly. I don't want heavy duty springs that will jack it up or make it drive poorly when unloaded. I just figure the old ones are worn out and I just want to get back to what stock was. Any idea of a good place to look for rear leave replacements that would be similar to stock, or should I just add a leaf to what I have?
