So basically the tundra spec shocks will/may be a little stiffer?
Also, as a side note, my understanding is that the 5100s have more travel than the 4600s. Is this correct, or is there another reason to go for the 5100s rather than the 4600s?
I'm primarily doing the upgrade because my original shocks and coils are shot, and I figured as long as I'm replacing them I might as well upgrade both the weight capacity and the ride height, and I prefer stiffer suspension in general, so I know I want Billies instead of OME shocks, but I don't want to limit the ride height advantage of the OME springs by using shocks that don't have enough travel.
