This is my first time posting. I have only ever read them and with that being said i know how crazy people get if they post in the wrong place and stuff like that. If i am doing this wrong please correct me and some guidance would be greatly appreciated. With that out the way. I own a 2016 ram 1500 4x4 with the 5.7 hemi. I have decided to go with the bds 6" lift and the fox 2.0 shocks. My question is to go with 35x12.5x20 which is the standard everyone has lift, or do I go with the 37x13.5x20. I want the 37s but I'm afraid that is too much tire for a 1500. I know the gearing is a factor but with 392 and an 8 speed I figured it could handle that just fine. If thats incorrect please let me know. I know i will be hurting with gas milage but here is a list of my questions if i go with 37.
1. Will the drive/ride be changed dramatically
2. Will the secondary parts wear out faster? brackets, steering system, powertrain, or anything else y'all can think of.
3. If i get bags put on it will I loose my tow rating because of the lift and tires
4. Will that lift and tires void any warranty
5. Will i need to change out the gearing
6. If their is anything else I'm missing please inform me.
Thank you for your help in advance.
Part of your decision on tire size will be based on what wheels you want to run. If you go with a wider wheel you won't be able to run 37's because of clearance.
With your truck having 3.92 gears and an 8 speed I wouldn't hesitate to run 37's though if that's the route you want to take.
As far as your questions go:
1. The ride will essentially stay the same with the lift kit or potentially increase if you install Bilstein front struts or coilovers with the kit. You'll definitely feel the lift and wheels/tires but the truck will still be very driveable.
2. The simple answer, yes. You're adding a lot of unsprung weight and rotational mass so that is going to wear the brakes, ball joints, bearings, etc. quicker. But it's not going to be a crazy amount. I'd call it maybe 25% quicker than stock to throw a number at it.
3. Technically, no. But you probably won't want to tow up at your max rating anymore because of the heavier and larger wheels/tires.
4. No. They may deny warranty on parts that have worn out because of the lift directly but they cannot void your entire warranty because of a lift.
5. No
6. No you've pretty much covered it all. From here it would just be nailing down your exact setup.
