After doing some research and not seeing a lot of people running traction bars on stock height trucks I decided to make my own and see how much difference they made due to the axle wrap issues on the truck. All i can say is wow. They cleaned up all of the spartan high hp tunes and made them perfectly dd in the congested part of town. I even drove the 310 around for a little while today in stop and go traffic. If you are debating whether you need them then don't. I have a much better appreciation for the quality of the tuning that spartan does now that i have solved what i thought was a tuning issue, but is really a suspension issue. Shifts are crisp and solid with none of the bone jarring that i had previously experienced. Hats off the second time to Spartan tuning. It is like gettin g all new tunes.
