Both use Leaf Springs here in the U.S., but the JT will use coils like the 2500. From the spy shots they will be using a similar rear set up to that of the Ram 2500 Power Wagon. Its probably why the tow rating is set at 6,500 lbs and they are not trying to beat the Colorado's 7,000 lbs rating. (but is still similar to the ZR2 rating)What do the chevy Colorado and Toyota Tacoma use?
No problem!That is pretty cool. Thank you for the information. I didn’t realize that the 2500 had coils.
