Lifting My 2021 Silverado Custom Trail Boss

In this video we unveil the lift kit on my 2021 Silverado Custom Trail Boss. This is the 2" ReadyLift SST lift for AT4/Trail Boss.

[@limitedslipautomotive]

Is nobody going to comment on me saying I listen to Kidz Bop...?

[@poarchboy33]

I have a 2021 as well, so it’s got factory 2 inch lift, what exactly is this set up to sit like this?

[@limitedslipautomotive]

@@poarchboy33 This truck has the ready lift 2” SST that goes on top of the factory 2” for a 4” lift.

[@dominikkai1452]

@Rogelio Troy I would suggest Flixzone. Just search on google for it =)

[@raulcrew5116]

@Dominik Kai Yup, I've been using FlixZone for years myself =)

[@rogeliotroy2237]

@Dominik Kai thank you, signed up and it seems like a nice service :) I appreciate it !!

[@BC_Hunter]

Looking at doing this exact setup but with 33x12.5” tires on a 20x10 rim with a -24 offset.

[@viahj]

wheel/tire size combo on that lift sits very well. but I'm a bit old school and would opt for a little more sidewall.

[@limitedslipautomotive]

According to ready lift you “need” 20” wheels to clear the UCA. If I could i’d run 18’s.

[@evanthomas7116]

Love the truck an also the scenery lol you live in paradise man!

[@berrytaylor9115]

Just a FYI your the reason I pulled the trigger on getting my trailboss last Thursday

[@limitedslipautomotive]

Congrats!

[@jasonworkman7912]

Thats excatly the truck im goin to go look at sat. Beautiful truck. Im like you, it has everything you need in a truck and nothing you dont

[@jmarco4331]

Great stance..... have a 19 LTZ and that’s the exact look I’m goin for but with the factory 20s . ....

[@limitedslipautomotive]

Thanks man!

[@gorillahd9247]

That turned out great! The truck looks awesome!

[@limitedslipautomotive]

Thanks man!

[@giovannimartinez2145]

Nice truck I just recently bought a 2021 ltz 1500 duramax

[@limitedslipautomotive]

Hell ya! I took the RST duramax for a drive.. things have some get up and go.

[@DriveAmerican]

Congrats, looks great! I have a shadow gray LT, the Custom looks more offroad worthy after careful review. Look forward to your updates

[@jamminjay]

That looks pretty cool! I have the same truck. I am only going to put the spacers up front to level it and get some wheels and tires. Probably get 20x10 Moto Metal wheels with a slightly negative offset and run 33x12.5 tires. Like to go 35's but don't want it to rub.

[@inanimateuser9828]

I have a 21 tb and my buddy has one too. He lifted his with just, the lower strut spacer at the lower control arm. He's only put about 4k mi on it so far but no issues. He was running 3pc 20s and 33s but went back to stock 18s and put 35x11.5's on it and they don't rub. I'm still on the fence about wheels myself, I put 1" spacers with my factory 20s and it looks good for now. Absolutely hate the rake and want 35's, but don't want to drop 600 on control arms and spacers after on it when I'm lifting it this coming winter. Probably will buy the spacers only since it won't be for long. Sorry for rambling on

[@pcb462]

You definitely have me wanting to get a new one now. It’s just hard to pull that trigger with no truck note in almost 20 years.

[@Ricky3610]

Do it man. You only live once.

[@alexmdc11]

NICE F’N TRUCK if I say so, I get your excitement cause that’s how I felt when I got mine! 🤣👍🏼

[@keahndunn5959]

Just subscribed, love the videos. I just bought the same truck in summit white with a few different features. Can’t wait to see what you go with for the LED headlamps. Interested about the price and how easy it is to install. Looking to do the same on mine eventually. I went from an LT to the custom TB and I actually enjoy the simplicity of it as well!

[@wyliezcoyote7834]

Lookin good!...I’m ready to lift my 20 TB but I wanna run 35x12.5s...so probably gonna use Zone Offroads 4” kit for the TB...🤘🏼🇺🇸

[@limitedslipautomotive]

Fairly certain I could fit 35x12.50’s on this with minimal plastic trimming. They would only be 0.4” taller and 1” wider than what I have currently.

[@wyliezcoyote7834]

@@limitedslipautomotive do you think there would be enough travel left for off-roading? I guess as long as there isn’t a ton of neg offset on my wheel choice...🤔🤷🏼‍♂️

[@limitedslipautomotive]

@@wyliezcoyote7834 Would probably be close, but you are correct. Offset and wheel width would have a significant impact. A 9 wide with 0 offset may be the ticket.

[@enriquepaz9726]

Have you done any towing? How’s the towing ride?

[@limitedslipautomotive]

Yes I’ve pulled probably about 20 times. Feels just fine to me. Haven’t gone anything above 8k lbs though.

[@BERTO929]

Looks great

[@etnies88]

Good video, Just bought this kit today now I need to put it on. I just hope the CV angles are not as bad as some people say.

[@limitedslipautomotive]

I will do an update

[@etnies88]

@@limitedslipautomotive I got the front done today and the CV’s look good, full droop it’s not bad but not great. I had some nuts missing from my kit too. The bolt on the UCA on the driver side comes very close to the ECM and touches the harness. Not sure if this is because I have the 3.0 Those were just my findings, I think when people try to add the 4” on the non trail boss or at4 is when thing go downhill.

[@Blackocalypse]

Hell yea bro welcome to the lifted life

[@limitedslipautomotive]

Love it man!!

[@Blackocalypse]

@@limitedslipautomotive 💪🏽💪🏽 Hell yeah🔥

[@dp935]

Looks real good. I have a 20 TB. I wanted to lift it up but most level kits require aftermarket wheels. I don't want to have to buy wheels and tires yet. I might do it. If so ill opt for some 17s. Keep us updated.

[@limitedslipautomotive]

ReadyLift says that you can run factory 18’s on this lift, but the tires will rub the UCA at full lock. Many kits require at least a 20 to clear the UCA unfortunately.

[@KevinJohnson-yo6es]

Looks badass man.. no doubt.

[@limitedslipautomotive]

Thanks brother!

[@BC_Hunter]

Is this 4” lift with plus factory 2” lift (6” total”)?

[@limitedslipautomotive]

No, this is a 2" kit that adds to the factory 2" lift. Total is a 4" lift.

[@theaverageguy8034]

Looks nice enjoy 👍

You need some method NV's man bronze ones . It will look good with that shadow of Grey

[@limitedslipautomotive]

Bro I was actually just looking at Nethod NV’s

[@simonpetertherock]

I have to agree bronze wheel with Shadow Gray is the way to go !

[@davidtadlock2238]

Bad ass truck man, I’m personally a fan of the stock look of the trail boss but yours looks great! Great content man, if I look to a newer truck than my 2015 f150 fx4 ecoboost I’m looking hard at the trail boss custom

[@limitedslipautomotive]

I love this thing.. I’ll give it to Ford, the EcoBoost trucks are fast as hell, but I love my V8

[@davidtadlock2238]

@@limitedslipautomotive I still can’t stand the aftermarket exhaust sound on the ecoboost, I have a resonator delete which is the best sound without sounding like a car. The only other way is if they have an extreme setup with turbo adapters, down pipes and exhaust then they sound gnarly. But you’re right they are pretty damn fast. I love a v8 due to the simplicity. My step dad has an AT4 5.3 with the 10 speed and it’s phenomenal, that 5.3 is such a workhorse.

[@jaleelroberts3374]

What’s the exact dimensions of the tires?

[@limitedslipautomotive]

285/65/R20

[@coopersdad2115]

Beautiful truck man!! I I was wondering if the dealership was able to update the speedo with the new wheels and tires you had installed? Thanks for the help

[@limitedslipautomotive]

They were not willing to reprogram the speedo.

[@RichardBrock-yi8ee]

What is the overall height of the truck?

[@limitedslipautomotive]

To the roof or to the fender?

[@fLAviii0]

Any trimming needed with those 34s ? And what about wheel spacers ...

[@limitedslipautomotive]

No trimming and no spacers!

[@heathsmith3998]

Does it rub at all? Rub when backing? Any cutting of inner fender?

[@limitedslipautomotive]

I haven’t cut anything.. it rubs under certain conditions, mostly when backing up. However, there are times when i can do full lock going forward and nothing rubs.

[@jm-zh1pz]

Yooo I’m in the springs, i just got a TB let me know when you are going to the trails to join you. Badass truck btw looks amazing.

[@limitedslipautomotive]

Glenwood?? And thanks brother, congrats on the truck!

[@rocker1889]

I have a 2021 Silverado Custom. My biggest gripe is how UNcomfortable the driver's seat is. No lumbar support and for height I have to sit on a pillow. Looking to trade up to an LT Trail Boss later or just see what 2022 brings us.

[@koryfrost4803]

Can you please post the exact wheel and tire specs that are in the video. I know you said no rubbing or cutting. Trying to see what I can get on my 20 TB

[@koryfrost4803]

@@limitedslipautomotive thank you sir!

[@ChrisFowlerRacing]

Do you know if you can upgrade the suspension with this lift? Readlift says they only tested it on factory shocks, but that doesnt mean it doesnt work with something like Fox or King Coilovers lol. Just curious if anyone has done it yet or tested it out

[@limitedslipautomotive]

I wouldn’t see why you couldn’t, as long as you’re only replacing the shock within the front strut assembly.

[@jasonyoung8614]

I'm looking to do the same thing on my 2019 custom trail boss, can you tell me exactly what rims and tires you have?

I want to go with ready lift until I got on their website and saw this disclaimer on the 4' sst kit. "Note: NOT intended for off-road use or abuse."...I think I would rather spend a few hundred more and get a zone or BDS kit with lifetime warranty

[@limitedslipautomotive]

I saw that, but only on the 4” for the “regular” trucks. I didn’t see that disclaimer for the TrailBoss.

[@JustinVachon]

Use a heat gun to get rid of those cheap looking trail boss stickers. I just took mine off my 2021 midnight edition LT Trail boss and it looks way better.
