I found a set of long travel Gibson a-arms with remote shocks for pretty cheap. I know the shocks are a pretty decent set but wondered about the a-arms. Are they pretty durable? How much are they worth?
Gibson calls those spherical bearings and though it's more like a heim in design than a ball joint they should not to be confused with "cheap" a-arms which use "heim joint" upper and lowers as the sleeves for the Gibson bearings/joints are part of the arm itself.
The benefits are that they are stronger and allow for a greater range of movement. The downside is that they are more susceptible to the elements.
