Measure the current gap from your tires to fender and you can enter it into the tool and then you can play with offset and tire size to get a flush fit.

I also have the pro truck kit with the upgraded coil springs. I got kryptonite UCAs and I love the setup. My brother liked it so much he got the same suspension but went with motofab UCAs. Both very pleased with Eibach. I would imagine the coilovers are going to be great.

Im running 285/75/17s (34s) on +0 methods with a 2.5in level from eibach. i had to trim fender liners and it still rubs a bit when locked in reverse. I will mention the Toyo MTs I have run a bit larger than others in the same size. Other wise they work very well. i would think you need some more lift or to cut some more material out since you are using wider tires. worth mentioning is the stock wheels will have the wheel be sucked in a bit more than my +0 offset (stock wheels are usually about +24mm (1 inch) which means they sit in toward the engine compared to mine) So it may help you on liner rub (i think) but youll also be closer to the suspension/frame. tire fitment is kind of an art/ kind of just referencing everything else you can find and hoping it works. I think youll be ok if you get the 1inch body lift and trim out some fender liner plastic. But dont take my word for it. keep looking over the forums for anyone thats done it before and check out custom offsets website as they have people that post there fitment as well. Might want to use this website too, its what i use for all my trucks when i am thinking of using a new tire size https://www.wheel-size.com/calc/ It lets you compare your current wheel/tire to your new one and it gives clearance changes as well. very useful imo. You can take measurements of your current setups clearance as a reference if want to get picky about it and find how much space youll have left and the relative changes in tire position

I did a 2.5 level kit with new UCAs and 285/75/17s (34in) toyo MTs. So far Ive lost a like 3 or 4 MPG average watching the 25 mile avg tracker on the dash. I think stock ! was seeing like 17 or 18 more often and now im seeing anywhere between 13 to 15 mpg. I remember I lost at least 1 mpg on highway driving just from leveling it and removing the front air dam under the bumper. Im also not driving the highway as much with covid so thats a factor. Cruising on flat highway i used to see 18-20 instantaneous mpg but now its more like 15-17. I have corrected the tire size in the ecm btw. You will definitely see a difference and bigger tires are not what you want if you really care about MPG.

Do you happen to know if the seat covers fit the double cab? I have the full center console (no flip up) and the bench seat in the back with 60/40 flip up for storage

Im running roughly 34" = 285/75/17s on a my eibach 2.5inch level with some fender liner trimming. You can definitely run 35s on a 4.5 youll just have to pick your offset correctly. I believe mine were +0 or-6

Re using the nuts is probably fine. I would definitely use new u bolts though. The u bolts get stretched and yield a bit when they are torqued correctly. If you do that again they will be weaker. Its up to you but most people will tell you they are a one use item.

how are the balljoint angles? If the angles are more extreme than stock it can cause faster wear on the balljoints and the boots.

Im thinking this matte black wrap on my truck would have a very cool murdered look.

ngl at first glance i thought your truck was an avalanche lol

Ya I did alot of digging when I wanted to put this setup together. Its absolutely the biggest you can get on a 2.5 inch level. I think a 3.5 from rough country you may be able to get 35s but thats a theory. The Toyo MTs im running are listed on the website at 34.1 so they are as tall as your current tire but a bit wider. Any ATs in that size are probably gonna be around the 33.8 like you have shown there. Something else to keep in mind is the selection of tires is pretty small in 285/75/17 so your favorite tire may not be available. Other than that I would say go for it if you are looking for a totally new setup.

Main thing I always hear about is the AFM lifters going after awhile. To help with that on my 2017 I have tuned out the cylinder deactivation to help lengthen the life. If they ever go bad Ill just have to do the delete. Currently at 41k on my 2017 with no issues.

Yea Im loving it man. Only time it rubs is when I back out of the driveway and its at like halfway turned. Its rubbing on the plastic cap on the cab corner. Its very minor and I dont intend on doing anymore trimming. If i turn it full lock it moves past and doesnt rub.

I changed my fluids about a month ago on my 17 with around 39k on it. Im glad I did becuase a ton of shavings came out. I used amsoil 75w 90 in both the front and rear and their trans fluid in the transfers case. Did it myself and it took maybe 2 hrs to do it. I usually go slow and try not to make a mess. The trans flush cost me about 240 bucks at a local shop. They dropped the pan, changed the filter and refilled the rest with amsoil trans fluid. I think they replaced about 6 out of the 12 quarts in the tranny

Couple days ago I got my BBP tune in the my inbox and I downloaded it into the truck. I have to say it was worth the money as of right now. It took a couple trips into town and down the highway to get the transmission to relearn but It drives much better than stock. Feels more like my brothers 08 5.3l when you press the peddle it does what its supposed too. Throttle feels better and more responsive and the transmission behaves better at low throttle and from a stop. Shifts feel crisp

I think youll get a good ride with or without coilovers Since BDS makes a quality lift. The coilovers would make it that much better, I would say you need to ask someone who has the coilovers if its worth it since they are usually pricey.

I was very close to getting one of these kits. It keeps all the suspension angles stock just moves them down and keeps the stock knuckle and with the new struts it would probably ride very nice. The other benefit is it doesnt increase the front track width like the BDS and other lifts do

yea for sure a smoother ride. The angle on your control arms are pretty drastic rn. They should be back to stock/level with the BDS, plus the new shocks will be quality

Thats pretty skeezy that they charge you 160 bucks to update the maps. Does the onboard navigation work any better than a phone? GPS reception better?

Your not really going to find a leveling kit above 3.5 inches because it causing excess wear and ride stiffness. You would want to go with a 4-4.5 inch lift at least depending on what tire size you want. Zone/BDS are good companies to look at for 4.5 to 6inch lifts. Fabtech and CTS makes a good 4 inch lift as well

im on 285/75/17s (34s) with 0 offset on a 2.5 inch level and i rub on the plastic liners and ended up trimming them a bit. I would say with -6 offset and the smaller 285/70/17 (33s) you will be fine. On using those wheels I would check if you can even get the wheel over the lugs. Since the Taco lugs are smaller the wheel may not fit over your bigger ones. If they fit I dont see why regular 60 degree lug nuts wouldnt work. The other thing you need to look into is a hubcentric rings for those wheels so that they mount up right Something like this: https://www.uswheeladapters.com/shop/106-7810-hubrings/ Also another thing you may want to check out is the load rating is on those wheel. They may be lower than your stock wheels and could be an issue when towing or hauling

285/75/17s are almost 34s.

that looks clean

Nice to know everything worked out well. Now Im excited, Ive gotta get my logs together still and send em off. Sounds like everything Ive been looking for!
