Roadmaster Active Suspension or Anti Sway bar or add a leaf?

Right, I guess my point was that the shocks do not carry the weight, the springs do so upgrading shocks will not alleviate any sag.

Question about RAS and WDH setup
I hope this is okay to post this question here about RAS!
Does RAS affect the correct setup of WDH? From what I gather, RAS limits rear sag. From what I'm reading, the rear sag (or the increase in height of the front wheel wells) is used to correctly set up a WDH and appropriately transfer some of the hitch weight to the front axel. Could the RAS, limiting rear sag, in effect, cause an incorrect setup of WHD by keeping too much weight on the hitch and therefore preventing the proper weight to the front?
Alternatively, if a WDH is setup prior to RAS installation, would the WDH setup need to be revisited?
Any insight on how RAS and WDH work together would be appreciated.

But any time you modify your suspension (with RAS or whatever), you should re-adjust your WDH by checking the front lift before and after.

Hey Guys, new to the forum. I am experiencing the starting from a stop shudder. It's quite annoying. I tow a 27 ft fifth wheel camper. I used to have a 2008 5.4L 6.5ft screw, and upgraded to a 2013 Ecoboost 6.5ft screw. Old truck no shudder ever, new truck lots of shudder. After reading about axle wrap, the low end torque of the ecoboost is causing the shudder at take off. The 5.4L didn't have low end torque like this, so i guess it didn't happen. I barely notice it with one passenger, more noticeable with 6 people, very noticeable with camper hooked up. I am interested in trying the RAS system, as I love everything about this truck, but can't stand the shudder....my wife freaks out about it when it happens.
Guess I should spend the $$ on this.
Thanks for all the input and great posts about this issue.

I installed the RAS on my tuck this weekend. The install wasn't too bad. The first side took twice as long as the last side (about an hour total). It raised the rear end 1". I used the black disk. I tightened the spring until the black disk would barely fit. The swaying seams to be alittle better but not as good as I was hoping. I'm thinking about taking it all apart again & tightening up more to see if that makes it any better. I haven't towed anything yet so I can't say if its helped in that department or not.
When I was installing it I got stuck on how to tighten the spring so I called Nolan & he answered my question right away. Thank you Nolan.
I'm thinking about putting drop shackles on to level my truck back out. I don't have blocks so I don't have the option to remove them to level it back out.

Cmerollin, I am surprised no one else suggested it before. Being you tow this setup only occasionally try moving the lift toward the back of the trailer 6 inches. If you compressing that hard it means you are carring a ton of weight. That trailer allows you to balance the weight better front to rear. I am not saying make it light but take some of the load off the truck and let that tandem axle set take more load. If you can't back it up try loading it in the other direction.
