I have a 2012 JKUR with AEV 2.5 inch lift, front and rear bumpers, winch and Gobi rack. Just started towing a trailer. The lift kit has been on for over 60,000 miles, a lot of it highway miles with a heavy load. I think its time to replace the shocks, but last weekend i was replacing the factory front upper bump-stops when I noticed the front springs are very rusted. I have no issue with the kit, has served me well and I have an email to AEV seeing if its possible to buy replacement springs. Would it be better to replace the springs with OME or Metalcloak? If I did replace with another brand, do I need to replace anything else? My Jeep is heavy, so I'm looking for something that can handle the weight. Thoughts? Thanks.
