Go to the trouble. Have quite a bit of moto/bicycle suspension experience, but vehicle wise, it has been limited to rally cars. Giving them the info allows them to tune for specific bump amplitude/frequencies, i.e. washboard conditions. The info will definitely allow them to tune your shim stack for butter smooth on washboard, all without diving under throttle/brake weight transfer. IMO it would be silly to spend that kind of dosh on King's without getting that level of tune. If you get get access to some wheel scales, with the truck loaded as you will use it, driver/passenger onboard....now we're talking. Braap! Please keep us posted.
