Question:

I have a 2015 gmc one ton dually and carry a heavy Arctic Fox 1150. I have Firestone airbags in the truck but due to on board compressor failing then air leaks, I’m done with airbags and moving over to Timbrens. We’ve decided to now keep the camper on the truck full time and already have the GMRTT35D Timbrens. So my question is this. The camper is heavier on the passenger side which always causes the truck to lean off level to the passenger side when traveling. To remedy this problem, I thought of using the Timbren T68MR spacer kit to raise the truck on the passenger side to compensate for the heavier weight. Is that a acceptable solution? Thank you!

Expert Reply:

Using a spacer kit like the # T68MR to allow one side of the truck's suspension to engage sooner will give you more support on that side but since it's hard to say if that will happen to be the sweet spot you are looking for in terms of support it's not what I would recommend as an ideal solution. The best suspension enhancement solution I can recommend would be the RoadActive Suspension Kit part # RAS3611-CHD which is easily adjustable in support on both sides, installs very easily, and provides a smoother support than the Timbren kits which also helps improve ride quality and handling quite a bit. The Timbrens are known to make the ride quality rougher.
