It's common to uprate the load carrying capacity of a 110 Puma without raising the height as excessive lift can cause issues with the front prop shaft.
This is one option...........
You can fit H/D springs to the front as mentioned above, and you can fit 130 inner helper springs to the rear.
This is suited to a Defender fitted with a bull bar etc to the front, and loaded in the back for a trip.
Retaining the standard outer rear springs means little change to ride quality, but an increased load capacity with the addition of the helper springs.
Ride height remains close to standard.
