My truck rides like crap and the front bump stop only has a couple inches before it hits the pad. I have thought about getting some Tremor 6.7 springs for the front but I don't know if it would actually improve the ride quality any. Right now it is hard to tell this truck even has any suspension. It's a base XLT CC 4x4, 100% stock, with 6.7 engine. Payload is 2,330 on the sticker.

 

Check your door panel, it's not payload you are looking for but the gross front axle weight. I will say that going from 4400# front springs to 5200# the ride is great and I have yet to tap the front bump stops. You can check the beginning of this thread for spring codes and spring weights to compare with what you currently have.
