I'm thinking of buying a Defender with a 2 inch suspension lift and gas shocks, mainly for towing a horse trailer. When I mention the suspension mods to insurance companies (Sureterm, Lancaster) they say they won't touch anything with a suspension lift, and it is dangerous for towing!
The guy at the (unnamed) 4x4 specialists didn't think it would be hazardous!
Does anyone have advice on a) the safety of this scheme and b) what insurance companies will allow this?
I don't want to turn the thing over or invalidate the insurance clearly.
Funny how they manage to "specialise" in every category really innit? ;)
They're always advertising in the boy racer rags too, as "specialists" in insuring fast/modded cars for young drivers. When I had a 2.0 Sierra they wouldn't touch me, yet the non specialist big names quite happily gave me decent quotes.
I find it exceedingly hard to see how a 2" lift wouldn't compromise the stability of a tow vehicle. It might not be a huge issue, but if it is mainly for towing and you want your towing to be as safe and relaxing as possible then keep the suspension at its standard height IMHO.

If you want a Defender for mainly towing a horse trailer then don't get one with a 2" lift.
The lift will do nothing to enhance the vehicles towing ability.
I have 3 Defenders 2 have been lifted by 2" for offroading and have towed with them both but have now removed the tow gear (plough) all together and replaced with pure recovery points. If I want to tow then I will use the other one.
If you want to offroad the defender then that is a different matter and you will just have to put up with the towing side of things.
Critical issue IMHO is the height of the tow hitch. If that is at the correct level then I wouldn't expect the 2" suspension lift to have too great an effect.
If the hitch has been raised by 2" then watch out.
What is the "correct level"? I guess it really depends on your trailer but for no particular reason I think it's with the draw bar just a little bit above horizontal rising to the hitch rather than dead level or falling. Is that right?
Says him having just bought a trailer (handy for the dump and the bikes) and not really having a clue about trailers. B-)

hitch height is only critical on >1 axle trailers. on single axle trailers it's the balance of the load that's critical to get the noseweight right. I'd normally reckon between 25 and 50Kg noseweight. on a >1 axle trailer, noseweight is MUCH more if the hitch is too high and non-existent if it's too low.
Mine is a single axle trailer a shade under 3m overall. The dump won't allow trailers with more than 1 axle or longer the 3m without a permit. Guess I'm going to have learn to judge 25 to 50 kg by arm.

If you're brave or as in my case foolish, you could try putting a set of bathroom scales under the jockey wheel, it'll give you an approximate value. Remember to put a bit of wood on the scales too as a load spreader else the scales are apt to come out bent!
In theory, all tow bars should set the ball at the correct height. The present relevant standard (BS AU 113c), and for newer vehicles, EC Directive 94/20, requires the centre of the ball, when the towing vehicle is fully LADEN to its gross vehicle weight (but without the caravan attached) to be between 350 and 420mm from the ground. This should be compatible with any reasonably modern caravan, given one or two provisos:- ? If the car manufacturer chooses to set the tow ball height towards the upper end of the height range, and especially if the vehicle has a relatively high load carrying capacity, it may be that under normal operating load conditions the tow ball is significantly higher than this range. This is permissible according to the letter of the standard or directive requirements, but may result in difficulties achieving a well set-up outfit. ? Off road vehicles are exempt from the height requirements in the EC Directive, in order to permit them to achieve the necessary ground clearance for off road use. This may make a fixed-height tow bar inappropriately high for safe, stable on-road towing. When choosing a tow bar for an off road vehicle, therefore, ensure that it is either: (a) a fixed height bar which is similar in height to those made for conventional cars, or (b) a height-adjustable bar which can be set to an appropriate level for on-road towing or off-road driving.
The laden/unladen part is not an issue with a 7 seat DII, it has SLS to maintain ride height (when it works...) B-) The recomended ball centre height is usefull info though.
When I got the hitch fitted I made sure it was a height adjustable one, I was hoping to get the easily adjustable type that you see on the back of Defenders but I got a large plate with four sets of holes and a pin and ball hitch.
