Does the Roadmaster kit help eliminate the 50-60MPH shudder when empty? I've searched and read posts until I'm cross eyed trying to find my answer. I have a 2013 screw 4x4 and I have been going through the same battle as everyone here with ford. I Don't have the take off shudder when empty but I have a serious 50-60mph shudder. I'm just trying to justify spending the money to fix a $50,000 truck. Thanks for any input you guys might have.

Without driving your truck, I would say no it will not help. Where the RAS is designed to help is the take-off shudder that some people feel (5-15mph) and to help support heavy loads. It does take some of the bounce out of the truck on rough roads as well. The 55 mph shudder is most commonly caused by spark plugs faulty or improperly gapped, faulty COP, or in some cases a torque converter/ transmission problems. I have also found that the way these F150s transmit road imperfections to the cab sometimes makes it feel like it has a little shudder. Tires slightly out of balance could possibly mask itself as shudder too.

everything I have read leads me to believe the 50-60mph shudder is more trnas/torque converter related, not suspension related. so with that said I would not expect the RAS to fix the issue.

RAS Helps with vibration from axel wrap caused from pulling/hauling heavy loads.

As others have said the RAS will not cure or even help the 55 shudder as its completely unrelated to what the RAS works with (rear suspension).

I had the 55 shudder, never had the loss of power or condensate issue (yet). I attribute the shudder to the horrible factory tires (GY SRA's) and the dealerships inability to correctly balance them, I had them flip the black walls out upon delivery.

Once I scrapped the tires completely to BFG AT's I have not had any vibration issues at highway speed.

If you do haul or tow heavy loads the RAS will help at highway speeds with porpoising, it certainly did for me and made the ride much more comfortable.

Hope you get this figured out. I again would point you in the direction of the crappy stock tires and balancing.
