I ordered my SR lowering springs from AM a couple days ago but their panhard bar was out of stock. I've heard of people going a little while without installing the panhard. My question is since I don't know when they will restock, how long is it safe to ride with just the lowering springs?
You should be fine, I think at worst it'll just be causing uneven tire wear.
Guess the question I asked AM regarding the panhard bar that they completely ignored got answered just by waiting. So, no, they had no plans to have the panhard bar in stock when they put it on sale. They've done this a few times now and it's getting pretty annoying. I went ahead and ordered my stuff from LMR. Some of it's on backorder, but at least they give an estimated restock date.
when i ordered my SR springs, i had the same issue with panhard being on back order. i went ahead and installed my front springs, and i waited on the rear just to be safe. i received my panhard about 2 weeks later, but haven't had a chance to install yet.
