Anyone know the difference in the shocks used for the tow package compared to the stock ones for a 2003 super crew. The tow package says heavy duty Rancho shocks, but was wondering what this means in the real world.

 

They are technically Ranchos, having been produced by Rancho, but they're still nowhere near as good as the aftermarket shocks sold by Rancho (RSX or 9000X). But they are an improvement over normal stock. They are a little more heavy-duty.
