Hello everyone, I'm new here and looking to see if anyone may can point me in the right direction.
2018 Silverado 1500 7,500 miles
2.5" Summit performance leveling kit on front nothing in the rear.
Factory 18" wheels
285/75/18 Nitto Ridge Grapplers
No issues what so ever until I hook a trailer to it. When towing at 60mph + or - a couple mph I start getting a vibration. As speed goes up the vibration gets worse. I have had alignment rechecked, tires rebalanced, nothing jumps out when looking at it. Had my mechanic take a look.
Just wondering if anyone has had this issue before I take it to Chevrolet. I don't want to get the run around from them.
Before I go to Chevy I think I will put factory tires back on. If problem still exist I will remove leveling kit and see. To be honest I don't think I ever towed anything before I leveled it.
Guess I should have mentioned that I have pulled three different trailers with various weight's.
1. 21' bass boat tandem trailer
2. 16' tandem utility with utv
3. 14' single axle with zeroturn mower
With the varying weights the vibration starts at within 5mph of 60mph.
