I used to the Belltech 3" lowering shackles (includes the removal of the factory block) and I did NOT trim my bump stops. I have over 1,000 miles on it and no issues at all.
Here's mine with the 3" Belltech kit (blocks removed) I think it's perfect. And no, I did not trim my bump stops and I'm having ZERO issues with it. Lovin' it!
I've been getting to know my stereo and I've set a bunch of XM channels into my favorites and now I don't want all of them on there. It's easy to set the favorite- just hold down until it beeps, but how do you delete the ones you no longer want??
