    Anybody running this product? I am getting tired of the sag when loading up with camping and work supplies.

    Do you suggest the HD or standard version?

    Thanks.

    Heard it works great for towing. Just do a quick search and you'll find lots of info.

    Right on. I don't tow heavy loads so I think the HD would be more than I need. Just ordered the standard system. Thanks for the replies!!

    I have the RAS-HD for the past year and regularly tow a 27' TT. I bought the HD because I'd rather "over do it" with the heavier loads I pull/ carry. I previously had Sumo Springs only but added the RAS-HD after their was still a bit of sag and I wanted true support for the suspension and leaf springs. Porpoising has disappeared since adding the RAS-HD and towing has been much more pleasurable.....I also always tow with a WDH.

    Mine just arrived today.
    Went with the HD as I only wanted to buy once and can adjust as needed.
    Will be installing mine at 1mm spacing and see from there.
    I tow a small 20ft TT about 3500lbs then all my gear in the bed.
    It sags quite a bit. and from the reviews I've read and research I've done.
    I think this will solve my issues. Also I tow this trailer without a WDH.

    Has anyone used this system with the Ironman Foam Cell Pro suspension? I've been thinking about getting this but was wondering if anyone has the same type of setup.

    I use it in conjuction with HD suspension upgrades such as Dobinson's HD 5+2 leaf packs and Yellow Sumo Springs as well. My truck sags very little with over 3k in the bed.

    How much did it increase your lift in the rear when fully unloaded?

    There are quite a bit of folk running the RAS. If you use the search function you will find loads of info.

    I have the HD version.

    You will have a 1" lift with the SD or HD set at 25%. 40% will gain you another .5" or so.

    I installed an entire new HD rear suspension simultaneously, so I have no b4 and after lift comparison data. I just know the cheap ass literally made in Mexico components were total garbage and I'm glad they are history! Tundra might be assembled in America, but it is far from made in the U.S.A.

    I believe it increased the lift in the rear about an 1" or 1 1/2"

    I know when my bed is some what empty it raised the rear just over an 1” or so when I have a load in the back it’s pretty much level I installed it because my rear end was sagging now it’s perfect. Hopefully this helps
