Best Rear Coil Springs for 2005 4WD LTD?

Hi -

Anyone have any recommendations for replacement rear coil springs?

The choices and product numbers on Summit Racing and Rock Auto are giving me a headache.

I have a 2005 4WD Limited with Bilstein 5100s front and back. The Bilsteins added some lift to the front, which I like and it is all I want. No plans for beefy bumpers or winches.

It's mainly a daily driver, though I do occasional overland travel on maintained gravel roads, like the Camino del Diablo in AZ, the Saline Valley Road in DVNP, and PNW forest service roads.

Thanks in advance for any recommendations!
