  1. Looking in to leveling my 2018 Sierra and have been looking at the Halolifts Alumna 2.0 kit. I have seen reviews about their previous kit but could not find anything on the updated version. Also, if anyone has used this kit, which aftermarket UCAs did you go with? I intend to keep my stock 20" wheels. Thanks! https://www.halolifts.com/HaloLifts-Boss-Aluma-Ultimate-Kit-GMChevy-2007-2021_p_345.html
  2. Good afternoon. Last week I bought my first GMC. It is a 2018 Sierra 1500 crew cab 4x4 with the 6.2L V8. Years ago I had a Ram so I am new to this forum. I have been looking to buy the Bilstein 5100 leveling kit (which I had on my '06 Ram and loved) for the front and put it at max setting. I will also replace the rear shocks with 5100s as well. My question is what is the max size tire I will be able to fit after I level at max setting? I called my local 4WP store and they said I would have to keep stock tire size unless I went to 4" suspension lift. I have seen many posts with folks putting 275/60R20 and some with 275/65R20 tires but could never find a consensus on what is the max. Any help is appreciated. I look forward to many more mods for my new truck!
