D40 towing capacity.

Is there any way I can increase the towing capacity of a D40 Navara? I am considering replacing my 2004 Rally raid with a D40 but what is putting me off is the 2,600kg towing capacity, my boat & trailer weigh more than this. My D22 can tow 3,000kgs. I have looked at a Ford Ranger Wildtrack because this will also tow 3,000kgs. Any ideas?

????

the 4x4 D40's over here have a 3 ton tow rating.

a little odd as the D40 is heavier than the D22 but has less load capaisty

D22 ZD30 3 litre power !

Upgrade the rear suspension and that should over come the towing capacity of the vehicle.

Check with an engineer they will be able to tell you what needs doing.

its not just suspension it relates to the strength of the chassis, towbar mounts, steering, brakes, handling, rear axle weight, gross train weight, vehicle plates etc etc

I do not doubt that the car is capable of towing 3,000kgs but legally you must not exceed the manufacturers advised maximum. On commercial (HGV) vehicles the rating of the vehicle can be changed by changing rear springs/bump stops. I am sure I read on this forum some time ago that a member fitted an air suspension kit on his to increase the towing capacity.

It is interesting that the NZ D40 can tow 3,000kgs. Is it because it it a different specification, or is it the testing procedure is different?

I'm sure it can be done . . . . .

Hasn't someone on her had their D40 upgraded for towing the 5th wheel caravan?
Think he even got Nissan approval and is all legal and above board.

Somebody PM'd me yesterday regarding My Navara’s Towing weight increase for pulling a fifth wheel Trailer however, I mistakenly deleted the PM before I had time to respond and now I'm not sure who posted it? Anyway, whoever sent me the PM here is the answer:

My truck now has a Gross Train Weight (GTW) of 6500Kg (Navara Double cab is normally 5810Kg) the work, and certifying authority was taken care of by the Fifth Wheel Company. To accomplish the increase in GTW the truck has been fitted with adjustable air suspension complete with compressor and accumulators etc. The trailer is around 3200Kg but aprox 500Kg of the total weight of the trailer is actualy carried by the truck when the trailer is connected. . It must be stressed that the fifth wheel trailer is towed from a fifth wheel hitch similar to that of an articulated lorry and is mounted in the Navarre’s load bay. The maximum of 2600 Kg can not be increased vie towing from a conventional towing "ball". Another stipulation to towing such a weight is the Trailer must be fitted with an active breaking system such as air brakes.

Anyway, hope this helps the member who popped the question.
