Most if not all the aluminum wheels use stick on weights and they have black weights also the factory may not use those yet I know we do at my dealership when a customer has black wheels
The rear springs are different the Max tow are stiffer the spring rate is greater than the Rubicon I went from my Max tow rear springs to Rubicon take offs the ride is softer and squats much easier than with the Max tow springs, with hat being said I have a set of Max tow springs you are welcome...
Remember guys we are all not bad when it comes to service seems like it is hit or miss at most dealerships, I would like to think mine is one of the better so if anyone is ever in upstate NY in a small town called Owego look us up Royal Chrysler Motors
