Best thread for a long time
I dont really grasp why the Jeep Wrangler unlimited Rubicon have so low payload as 892 lb (405kg) in US. My Rubicon unlimited 2013 has little more 1200 lb (545kg) and it is probably because I have bigger brakes that al export Wranglers have outside US. But it is still low for Dana 44 axles I think.
I wonder if Payload has something to due with toppspeed of the vehicle, hmm
I do understand that a Landrover Defender 110 ordinary or heavy duty have more in payload because it has similar axles as Dana 60 and then probably bigger stiffer coils and springs. With heavy duty payload is 3042 lbs (1380kg) and that is about three times more than the Rubicon, does that mean that Defenders axles are three times as big and sturdy, three times as big and sturdy coils and chocks. A axle three times a Dana 44 would be extremly hugh and much bigger than a Dana 60. It do not seem right with the payload.
So lets look at Jankel Jeep J8, look at the specs at the end (page 23), it has front Dana 44 (as Rubicon) and rear Dana 60 and it has a payload between 2.556lb (1164kg) to 3667 lbs (1664kg) we say about roughly 3 times the payload a Rubicon has. Is Dana 60 3 times as big and sturdy as Dana 44, I dont think so.

On page 3 they write.
"Heavy-duty air cooling, brakes, suspension and a sturdy Dana 60 rear axle" There are bigger brakes on Rubicon export models
"Significant reinforcement of chassis for outstanding payload and towing capability"
I think also Defender have sturdier chassi compared to the Rubicon and is probably a important factor to increased payload.
I am still think that a Rubicon is regarded as a car and the defender and J8 is regarded as a truck and have different payloads ratings because you offen drives a car different and faster than a truck. I wonder if J8 and Defender would have thoose Payloads if they were for sales in US classifieds as personal vehicles.
Havent Rubicon a rather strong chassi and axles if it is made to be bashed on rocks on Rubicon, I mean Rubicon has the same payload as many cars made for the city.
Topspeeds
Jeep J8: 140 kph (87 mph)
Defender 110: 145 kph
Rubicon unlimited: 180kph
That payload a Defender can have means that it has good brakes? A test made here say that it stopped at 54 meters in 100km/h and that is not so good. This test is from 2007, so now it is maybe better. Google translated
