Thread: 6x6 drive and suspension

That would be partially load sharing (not sure if there is a technical category for that. If you swapped the coils for truck air springs and connected them in the same way then they would be fully load sharing.

Thanks Ben.

What about using the bags from an air suspension Rover?

Or would they not have sufficient capacity or length for a Defender susension?

You could, but there are much better and cheaper options from places like truckspring Firestone Air Bags, Firestone Air Springs - TruckSpring.com

Search for a thread by Hally and you will get all the part numbers. Rovercare, RangierRover, Hally, Bush65 and I all bought our air springs from them (or airbag man) AFAIK, and most of us have install threads with pics.


EDIT - forgot to mention, 110/130 rear coils are larger diameter than RRC/disco. So you can fit a larger diameter air spring to a 110/130 (or 6x6 coiller) than a disco/rrc rear.

The airbags from an RRC are about the same price ex UK as a firestone truck air spring ex US. However I think the wider springd would be a better option.

As I mentioned on the 6x6 thread in the Forward Control forum. Instead of the upper ends of the coils being mounted off chassis mounted brackets they could be mounted on each end of a longditudal see saw beam centrally pivoted from a chassis mounted crossmember.Would have to allow space for the beam to swing up above the height of the chassis top though.Saw it on an independantly suspended (swing axle) tandem drive truck(RABA) in North Vietnam.For all the complexity though it would be simpler and more elegant to use the traditional pivoting leaf spring and 6 straight control rods instead of beam plus coils plus A frame.
That other 6x6 thread went stone dead for some reason.

Try stamping that into a chassis. No idea what it means but its what they gave me.

Suspension design? Perentie too? What brand of FWH have you found that can stay intact on the back axle?

But don't you have Dana 44 axles instead of the Salisbury/Dana 60 that the perenties had???
