Rip got my DSS to me very quickly. Great service! I installed it yesterday in about 45 minutes. The whole concept is so simple, yet soooo effective. I'm quite happy with the performance and feel this will extend the life of my steering box for a very long time. The truck doesn't wander anymore and you don't have to anticipate the turns anymore, you just start the turning when you get to it. What a concept. Dodge should buy this design from Darren and make him a rich man. It should be available to everyone as a recall modification! FREE! Take the plunge, it is worth the very low price.
