Thanks for digging it up. I love this thread. I have a fleet of Tamtech buggies and enjoy reading about them.
Concerning the ride height... have you tried softer springs to simply lower the preload? Also, I have a set of the aeration shocks and they come with spacers (limiters) you can put inside on the shaft to adjust height. (Although, it might be pretty easy to do this to any shock, you just need something that will fit around the shock shaft that won't hinder smooth movement) Not sure if this would achieve the height you're looking for though. I personally like my droop set high for clearance since I mostly just bash.
