I’m trying to decide which one to do. Who here is running air bags on their TB? What brand are you using? I’m looking at the Firestone Ride-Rite 2906 kit with the spacers and the Loadlifter 5000 Ultimate 88388. The Firestone kit looks easier to install, but I’m not sure that is a good thing or bad. I’m also looking at the Sumo Springs 1500# set. If you have any of these installed I would appreciate comments and pictures of them installed (specif I’d like to see pics of the Sumo Springs installed).

I just placed an order five minutes ago for Timbren GMRS15 rear SES. I wanted additional support for RV towing and didn't want to have the continual adjustment of the airbag system. I was torn on Sumo or Timbren, went with Timbren although there seems to be fans of both. I called Timbren to confirm the fitment after finding differently referenced part number on the forums. Some people used GMR15MR. Anyone have any feedback?

I second the Timbrens, had them on my last truck and my current trail boss, they are great for towing in my experience. I ordered from etrailer.com along with an additional 1" spacer. There are a bunch of pictures on their product page as well.

I received the Timbrens yesterday. I will install this weekend. I ordered the ones recommended by their tech support. I was concerned about the different part numbers quoted and the lack of the TB being an option on their selector tool.


GMRS15

Looks like they may combine the standard rubber spring with a 1" additional washer to make up the truck specific kit. I held it up to the old bump stop and it appears to give approximately the suggested 1" gap to the bump stop. I assume that the extra height bump stop on the TB accommodates for the factory lift and is what makes this part work for all 4x4 Silverados.

Sounds good, from my experience it is easier to install by removing the lower tall bump stops on the TB to give more clearance to install the bolt through the upper rubber portion.
