Hello folks, it's been a while since I have posted. To start, I have a 2014 eco Bighorn 4x4. I bought it new in October of 14 and have 167,000 miles on him. It's been a fantastic truck! It is completely stock. No tunes mods or anything else. I tow a 35' Jayco that's around 7500lbs and it does a pretty good job. I did put a set of Timbren blocks in the rear cuz I still had the original shocks on it. It's time to change the front struts. I put Rancho 5000x on the rear last fall. Are the springs good to use at 167000 or is it time to replace? I have been looking at coil over assemblies or should the old springs be ok? I have not beat up this truck in anyway. My miles have almost all come from highway driving. Thoughts?
