Bilstein 170/60 vs 255/70

It’s time to do something about my rear shocks , the 5160s just aren’t the right length. I’m not looking to go with crazy high end shocks which let me play with custom valving so prefer something OTS.

I don’t know which of the two valving options is best for my application. I have hd dakars , a shell , I tow a teardrop , and often have extra weight in the back. I’m leaning towards the higher rates fwiw.

I have a couple of questions, which of the two rates is closer to the 5160s ? Which is closer to 5100s?

What have you run and what was your experience? If you chime in on this one let me know your setup , springs, shell , towing, usage etc.

Thanks yall.
