I'm looking to get new cab mounts all around. I'm thinking of getting the fully adjustable rear mounts with horizontal and vertical adjustment. I have some concerns though because it is basically a fixed mount. I would assume the original arm was designed to allow the frame to flex without twisting the cab, so would changing to the fixed mount be asking for trouble? Does anyone have the adjustable mount I'm talking about and had any issues? Any thoughts would be appreciated.
I would think that if you are keeping your truck stock that you would wamt to keep the original style mounts.
I have modern suspension components and a partially boxed frame,MII front and 4-bar rear with coils overs, and a big block engine, so I don't want the frame to flex.
I used the fully adjustable mounts like you described and it made mounting and aligning my cab a breeze. I would do it again the same way.
I'm not concerned with staying stock. I have a MII with the framerails boxed up to the firewall, but stayed with a rear leaf suspension. I am leaning towards the adjustable mounts, but just wanted to see other peoples thoughts before I dropped the cash.
What I should have said was that if you are going to use it like a truck as in the stock manner, that you would probably still want to allow for the frame to flex more. I'm sure my truck still flexes some but the new mounts haven't caused any problems after about 3000 mi.
