Re: Cummins leaf springs
Same here. My orange truck has rough country 4" springs and they've been in there for over 6 years. I haven't had any issues with them at all.

Re: Cummins leaf springs
Here is a good supplier to get springs from. I've purchased many pairs of different springs from them and the shipping isn't crazy expensive.
