Extra Lift Support For 2019 GMC Sierra AT4

Question:

I have a 2019 GMC Sierra AT4. Will the TGMR15MR fit my truck and do I need to get spacers? (Truck does not have "Adaptive Ride Control" or "Magna Ride." Is not loaded continuously or with a slide-in camper.)

I spoke with my contact at Timbren about your AT4 truck, which has a 2" lift from the factory and the correct kit for your truck is the Timbren # TGMRCK15S Rear Suspension Enhancement System

You mentioned "extra lift" in your question title. I want to make sure that you understand that this will not lift an unloaded truck, but rather help it not to squat down in the back under a load.

You also asked about spacers. When installed (in an unloaded truck) there should be about 1" of space between the rubber spring and the axle. Your kit is designed to fit your truck and the need to purchase spacers is unlikely.

I have attached a link to this product page and a couple of review videos.
