Has anyone put on the front splash guard delete kit onto there 2021 GMC AT4 1500? If so do you get a lot of stone chips along the side? Or do the running boards take the brunt of the stone chips? I put the bilstein front strut and coil over kit on set to circlip#3 setting about 3 months ago which puts it at 1.2" higher in the front. Since then it has settled to about 1" and now rubs the front flaps on hard turn forward or reverse.....mostly reverse.....and is much worse in 4 wheel drive. I am probably going to put the readylift 1.75" leveling kit on to see if it makes it clear my toyo open country AT LT285/60/R20 tires with fuel 20" wheels with +1 offset on the current gmc splash guards, but if not then I may just put on the front mud flap delete kit. Thank you

Looking for an answer to a question I couldn't get a solid answer from ready lift on. I have a 2021 gmc 1500 AT4. I replaced the rear shocks with bilstein B8 5100 shocks on the rear and the bilstein B8 6112 suspension kit with springs and adjustable circlip for ride height. I set the bilstein front struts at the #3 circlip setting to give me 1.2" of front level. After it settled it was closer to 1". I was going to install the ready lift 1.75" front leveling kit on my truck which comes with new Upper control Arms, bushings, ball joints, etc. Question 1- will this kit work with the billstein front suspension kit with the billstein B8 6112 struts and coil over kit? Anyone put the ready lift 1.75" level kit on with the bilsteins? Question 2- I put the front circlip setting onto #3 which says 1.2" of level in the front. If im now installing the ready lift 1.75" leveling kit should I set the circlip on the billstein front struts back to the #1 setting which says "stock" ? FYI- the number 2 setting on the billstein strut says it will give 0.6" of front level. My guess is you would want it set back to the #1 "stock setting" ?? Question #3- anyone that has put this ready lift kit on, have you noticed a more stiffer ride? Im a plumber, not a truck mechanic....but I would think with the strut spring spacers that you would be compressing the strut and coil some and would give a stiffer ride????.....which is also another reason that makes me think the front strut setting should go back to the #1 "stock setting" ??. But like I said, im a plumber so thats why im here asking the experts. Oh, one more thing.....I have LT285/60/20 toyo open country AT tires on the truck with Fuel 20" +1 offset wheels. Think tires and wheels will clear the readylift upper control Arms and factory mud flaps? Would hate to have to start hacking up the truck. I attached a picture of the bilstein front suspension kit I have on there now. Any help or advice is appreciated. Thank you.

Thank you....looks like a clean fit. I like the license plate to!

Thank you, what year and model truck is yours on if you don't mind me asking? I appreciate the review......wonder if you got defective one? Can you exchange it?

Good call, been looking for the same thing for my retrax pro. Thank you

Anybody install this light bar on there truck yet? Any electrical issues or codes thrown after?? Thank you. 60-Inch Blade LED Tailgate Light Bar by Putco - Associated Accessories Part No. : 19418352

That's what the flip out storage is for in the rear seats of the AT4.....I literally have everything in there you mentioned along with a roll of TP. I You never know what will happen on the jobsite. I think they designed that storage with this in mind .

I have the same truck and same year......the only bulbs halogen are the 2 license plate bulbs, which I dont understand why GM couldn't make those LED like everything else. The Lasfit brand license plate bulbs are the ones to get in my opinion, they say on there website it wont throw a code. Have had mine in 2 months and no code issues.

https://gr1performance.com/product/2019-2020-gmc-sierra-1500-only-fits-at4-and-slt-2pc-black-overlay-grille/ Welcome to the forum.....great info here. I was told possibly not on the elevation grille on my AT4. I ordered and just recieved this gloss black grill overlay for my 2021 at4. I haven't installed it yet but dry fitted it and its gonna look nice. Very well made. There's a great video on this product on there website and on YouTube. I figured for $195 shipped with the coupon on G1 Performance website it was worth a try. If I don't like it can always take it off with a heat gun and look into other options.

Thank you for the information, i truly appreciate it.

Thanks Rob, looking forward to getting it installed.

What tuner option are you thinking of going with?. I didn't think they unlocked a tuner for 2021 6.2 yet? Will the tuner your thinking of shut off DFM to? Thank you for any info.
