The link length will make no difference Shayne. If the wheel is attached both ends to the ARB it's still attached. With disconnects you free off each wheel to rise and fall independently. In standard form the ARB will be able to cope with both wheels moving in tandem (as in when the car is lifted on a two post car ramp) to both extents of the shock absorber which then forms the top and bottom limits of travel. this would happen at both link lengths but you would be hanging the ARB ends and links further down and likely to be damaged with no benefit. Unless of course the ARB hits because of your lift. In which case they would need extending to stop the ARB hitting.
If you imagine the arb is like a bow and the links are the bow string , when you lift you are pulling on the string adding tension to the bow that's why +2" suspension always calls for +2" links because it puts the arb back where Toyota wanted it so there's nothing new in my thinking .
What i'm questioning is why not put slack in the string by adding an extra inch to the arb link ?
What i'm thinking is as a result one wheel would have be on a pavement before factory spec tension in the bow was reached .
(the bar does flex several inches anyway)
I lowered the bar mounts to bring my arb back into spec but i feel my bow is already loaded and ready to fire - lift the opposite wheel in sympathy . Maybe its just the heavy duty suspension i opted for
Disconnects are no good because i have gotten to know the driver well enough over the years to know he will remember to disconnect only after all the obstacles have been passed and remember he hasn't reconnected when doing about 90mph on a motorway
I don't know i just get the feeling there is more to the dynamics than twisting the bar - the length of the lever that does the twisting for instance ????
I guess its one of those trail and error suck it and see things but it would be nice to find a compromise and nobody as yet has warned against the extra length .
You replace the drop link with a small hydraulic cylinder. When valves closed they are solid. With valves open they can move back and forth giving extra articulation. Never tried it. I've heard of it on some vehicles though.I won't be doing hydraulics Rich its a bruiser not a Rolls Royce
