if you are going longer dog bones, doesn't that mean you need longer A arms as well ? ...
i don't get how longer dog bones works with longer shocks but without increasing the A arm length ..
unless someone else has done this and has solid prove that it works, i say no
and its still relatively unclear why you want a higher ride height ?
on top of that, buggies aren't really made to have high ride heights.
that's why someone invented "Truggy" combining a buggy and monster truck like vehicle into 1.
@Xraycer mentioned to increase the tire size, i also stand by his opinion.
@tntpoof mentioned using heavier or thicker shock oil to increase resistance and minimize shock droop and increase shock length.
However at the end of the day the A arms only go so far .. even without droop screws they would simply be limited by the chassis.
The link you posted, with the fastrax shocks, its the same length you already have in the front. therefore you would be gaining absolutely nothing. apart from losing money.
