At the moment, Im ready to re-oil my suspension. In the process, i wish to change the valves to an aftermarket types. As far as im concerned, there are two types you can get: Race Tech and Pro-Action. These two have differant set-ups in the actual valves. Im just wondering which of these two work better? I also know that with the Pro-Action, you have to get a qualifed person to fit it, which im not concerened about.
