  1. I apologize up front if this topic has already been brought up. I am a new member and looking forward for some help. I have a 2017 Chevy Silverado 1/2 ton Z71 with 6.2 liter engine, 3.23 gears and 8 speed transmission. I have a drop in K&n air filter, flow master muffler and will be doing a lift kit with larger tires and wheels. Those of you that have experience with this motor and chips, what’s the best. I am looking at Diablo or Sport Chips. My pervious 2012 Sierra with 5.3 liter, I ran the Hypertech Max Energy and absolutely loved it. It made the truck feel night and day difference. Hypertech currently does not support the 8 speed tranny so I need to look for another chip. My driving is 70% city/highway, 20% towing boat/atv hunting trailer and 10% offroad wheeling. Look forward to seeing what chip is best for my 6.2 and what settings you found to be the best. I want good power, string shift points and added mileage is a benefit. Thank you everyone.
  2. Dear members, I am new to this forum so I am hoping I came to the right place for some help. I recently purchased a 2017 Chevy Silverado Z71 Crew Cab Standard Bed with 6.2 liter and 3.23 gears. I am going to buy a lift kit for my truck, but having a hard time deciding what size due to gear ratio. With a lot of research I have decided to go with BDS lift with the Fox 2.0 shocks. I will be going with 18x9 wheels. My stock tires are 275/55/20 (31.9” tall). If I go 4” lift I will go 275/70/18 (33.6” tall) and if I go 6” I would go 285/70/18 (34.1” tall) or 295/70/18 (34.5” tall). I will be going with Toyo MT or Nitto Trail Grappler MT tires. I love the look of a 6” lift, but worried with the 3.23 gears, the close to 35” would be too much for the truck and kill my power/mileage. I could always regear the truck if needed, but what to, 3.73 or 4.10? I love the stock performance and gas mileage I have now with stock tires. Would like to bring it back to what I have. For looks, mileage, power and being practical, the 4” would probably be the best with 33” tires. Problem is, I don’t want the truck to end up looking like just a leveled truck. I want a nice stance to it. My 2012 Sierra with 4” Fabtech and 285/70/17 tires looked like a leveled truck. I believe the newer body styles are taller though so I am hoping the 4” will look bigger than my previous 2012. Do any of you have experience with the 6.2 liter and lift kit/tire size combo gas mileage and power? Also would it be possible for any of you that have the same truck as me with a 4” or 6” lift kit tell me what your front and rear measurements are from ground to bottom of wheel fender? Curious what the height is so I can compare to my stock truck. Look forward to any of your advice in helping me decide what lift, tire size and gears I should go with that benefits my needs. Any help would be much appreciated.
  3. WhiteLMM, what gears did your friend end up going with on this lifted 6.2 liter Chevy? I have been researching online regarding re-gearing and ran across your post. I just bought a 2017 Silverado 1/2 ton crew cab standard bed Z71 with the 6.2 liter motor, 8 speed transmission and 3.23 gear ratio. I am going to lift my truck and having a hard time debating between a 4” or 6” BDS. I love the look of 6”, but afraid with my high factory gears, it would require re-gearing. If I go with a 4”, I will run 275/70/18 (33.6”) and if I get a 6” I would go 285/70/18 (34.1”) or 295/70/18 (34.5”). The tire I will be going with is Toyo Open Country has MY. My factory stock tire is 275/55/20 which is (31.9”). Currently with my stock setup, I love the power and gas mileage. Just too short now. Need my lift on. Most shops I talk to say to re-gear, but I don’t want to do lower gears and regret it with my truck sucking gas. So far people are saying 3.73 for the 33” tires and 4.30 for 34”/35” tires. Look forward to hearing back from you.
  4. Vic15, I have been researching online regarding re-gearing and ran across your post. I just bough a 2017 Silverado 1/2 ton crew cab standard bed Z71 with the 6.2 liter motor, 8 speed transmission and 3.23 gear ratio. I am going to lift my truck and having a hard time debating between a 4” or 6” BDS. I love the look of 6”, but afraid with my high factory gears, it would require re-gearing.

My factory stock tire is 275/55/20 which is (31.9”). I noticed you have the same motor, trans and gearing as me. On your 6” lift, what size of tire are you running. How is the performance and gas mileage for you currently. Do you plan in re-gearing? Most shops I talk to say to re-gear, but I don’t want to do lower gears and regret it with my truck sucking gas. So far people are saying 3.73 for the 33” tires and 4.30 for 34”/35” tires. Look forward to hearing back from you and getting your feedback as you have the setup currently. Thanks man.
