suspension drop and a-arm bumpers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can anyone speak from experience about a 2" drop and the a-arm(upper and lower) bumpers? Do the originals work just fine or do they need to be shaved?

I will have to let someone else answer this one, but I believe that with a 2" drop you will be find with the factory bumpstops.

I'm going to get this moved over to the suspension section for you as well, hopefully a few more responses for you over there.

The upper A arm bumpers don't matter on the drop. They are there to keep the suspension from overextending when unloaded.

On the lower bumpers, you will be fine with a 2 inch drop. After driving it a few weeks, you might look at the bottom of the crossmember where the lower bump stops hit it. If you see a shiny spot in the grime, you can know that the snuber has been hitting it, and you can trim accordingly if needed.
