    Is there a significant difference in empty ride quality between Hendrickson rubber block and the KW AG100. My W900 has the rubber block suspension with the optional shock kit. I never got to drive this truck down the highway due to it having rotted tires and no lights when I bought it. (I had it hauled home). I am going to look at some KW AG100 cutoffs tomorrow but I think they are going to cost me more in the long run to make the AirGlide functional in my truck vs simply rebushing my Hendrickson and bolting it back into the truck (I estimate it'll cost $2k-$4k more to have the AG rebuilt and welded in with a double frame installed). Does the rear axle shock kit make any significant difference when empty? I do plan on removing the round heavy duty block from the center on each side since this truck won't likely ever turn a wheel for profit.

    I am in the middle of swapping my AG100 for a Hendrickson Haulmaxx. Just pulled the AG out yesterday.

    I was just about to start stripping down my axles and suspension this morning when I came across the AG100 cutoff on the internet. I called him up this morning and I think I'm going to move on this. My next question is can I legally weld this cutoff onto my existing frame and insert a double frame for strength? Will it pass a CVIP inspection? Or would I be better off just drilling new holes in my existing rails?

    Not sure on the rules where you live regarding frame welding and what not.

    But to answer your question on ride quality between the 2 .
    There would be no comparison ,the ag100 is prob one the nicest riding suspention around .
    It don't handle worth a crap but she rides nice!!

    Your rubber block would be up there with the worse riding there is empty.

    The shop where I go does this all the time. First they weld the frame together and grind it flush. Then they get a 36 inch piece of frame rail to put inside the frame rail with six bolts 5/8 each side of the weld. Then they put a cross member in the double frame piece so the weld is in the middle of the cross member bolt cross member in You really need a mag drill for all this drilling. This will never fail he done many of trucks. (this just my opinion)

    2nd terryt. Saw some Mack Midliners done similar from the factory. Some long factory trucks have a second rail that only have the top and the side. Have seen stretches with a gap between the bottom flanges, works but looks wrong. Have had a fab. shop make a rail to my spec. if I could not find one that fit right. Always rented a magnetic drill press for big jobs, they are expensive. Personally preferred to stay with the original rail with what you are doing but its a lot more work. Would not weld the inner and outer rails together on a splice. I do not recall any CIVP regulations on welded frames just cracked ones. A well done splice like terryt outlined is noticeable to very few anyway.

    They make a kit to convert your "R" beam suspension to air ride called Hendrickson AR 2. Local shop here in SLC quoted me $12,000 to convert. $18,000 if you don't already have "R" beams. Google it. I can't post a link as I'm on my smartphone.

    I was thinking about that but $12k is a little out of my price range. My truck needs absolutely everything done to it so anywhere I can save a few bucks is a plus.
