...if interested I'm taking my Roadmaster Active Suspension kit off tomorrow and will be selling it. Trading my truck in. Works great--reduces squat when towing, cuts lean on cornering and doesn't really effect ride. You can pre-load it and raise the rear a little when unloaded too--I lifted it about 3/4" and that worked perfect with a 2.5" front leveling kit from Rough Country.

not a salesman, just a happy customer. i installed these on my 2014 lariat heavy duty within a week of owning it. i have put 2000lbs in the bed with out the truck even noticing it.
