It is not just the Equal-i-zer hitch that requires those torque numbers. Most hitches manufacturers, other than a select few, require the bolts for the hitch head and the ball to be torqued to almost the same numbers.
Not sure what "most" would mean as there are so many WD systems available on the market today and each has it's own specific requirements for correct installation. The Blue Ox Sway Pro, as an example, requires a torque wrench capable of 257 ft-lbs and since those rated to 250 ft-lbs are quite common and not that expensive this is much easier for most owners to achieve. Second point - unlike the Equal-i-zer the Sway Pro has a fixed head with a fixed head angle, therefore there's no need to install or remove head washers as there is with the Equal-i-zer. In other words, installation is MUCH easier as there's so little involved in installing a Sway Pro correctly.
