So ive been seeing the conversion on 08-13 Sierras , and very popular on Silverados even the 14-16 conversions. On feb 1 some jack ass cut me off and hit my front bumper and fender , lucky for him i was already looking into doing a 2018 denali headlight conversion with the gen5 wiring harness and 2015 HD front bumper with 2500 all terrain grille To keep the theme going. As I researched could not find anything on the 2014-2018 sierras being converted to HD , all the guys i saw on IG with them had shops or buddys do them. Some guys welded either the 1500 or 2500 brackets lower ,enlogated the holes lower, redrilled , some had no gap -some liked oem gap between the grille/fenders. I did find two guys I kept intouch with they were a lot of help. One sent me pictures on how to re-drill the stock bumper brackets lower and cut some parts off it to clear the bumper , the other told me 1/2 above the existing holes . I took it upon myself to source a complete front bumper from ebay with everything $750 with shipping all i have to do is paint it , found a all terrain grille on ebay for $300 , had to buy the 2500 bumper guides and 2500 bumper fillers no luck on hood yet.while the parts arrived i bought the 2018 denali lights from fankie on here and the harness from gen5 easy bolt on by the way. When all the parts arrived i grabbed my grinder and drill .
To start i took the 15torque head screws and 7mm from the sides of the wheel wells , took the 12 plastic clips from the upper cover , removed the 4 top 10mm bolts ,pulled off the bumper filler pieces between the grille and bumper , exposing the 10mm 4 bottom grille bolts , then removed the grille. Gaining access to the 4 18mm bolts that hold the bumper on the brackets, i loosened but did not remove till i went under the front bumper and removed the 2 outter 15mm bolts that hold the bottom of the bumper , i loosened the inner 15mm bolts but did not remove , once that was done i removed all 18mm bolts holding the bumper and took it off . Once off the stock 1500 bumper brackets have 3 15mm bolts in a triangle pattern, i removed all 6 and removed the tow hooks , the tow hooks will be eliminated from this . Once i had the brackets off i measured 1/2 inch above each hole . Now this is important if you want oem gap like myself i drilled a hole slightly bigger than the bolt going threw at the center of that 1/2 mark . If you dont want gap id suggest drilling under the 1/2 mark and possibly enlongating that hole down wards for adjustment. By drilling the hole a 1/2 inch higher it drops the bracket to clear the 2500 grille . In addition to redrilling the bracket you have to cut an L shape on top right next to the top bolt that the bracket has , i actually cut the bottom of the bracket and eliminated the bottom slot for the second 18mm hole because i was having issues lining up , ended up not being the problem , i found that out of the 6 15mm bracket bolts you only use 4 the top and inside 15mm the outter 15mm that completes the triangle actually hits the hd front bumper and it sags in the back ,so removing levels the bumper flush , i tried grinding the head down and still no luck removing was the fix. With the bumper off , you want to remove the 1500 bumper guides 3(7mm) bolts rachet wrench works best and socket aswell , install the 2500 bumper guides with same bolts same place these support and clip on to the new 2500 bumper filler pieces under headlights which youll have to buy . They clip and slide right on , the two bottom outter 10mm bolts that held the old grille will hold these in place and the other two 10mm in the middle from the old grille will be eliminated. See pictures.To finish securing the bumper filler and guides you have to screw the 7mm and 15 torque screws by fender trim , you will either have to buy the 2500 or 18 fender trim pieces or just trim yours roughly enough to bolt on the remark to trim perfectly and level like i did cant even tell .So Once the guides and fillers are installed grab the redrilled bumper bracket to your liking in gap, make sure its clearanced with the L shape you can rebolt bolt to frame leaving the outter 15mm off at that point you can lay the new bumper on the brackets rebolt the top 18mm bolts the bottoms wont line up -i eliminated by grinding off ,see pic -you can reconnect the lower 15mm outter brace and tighten , youll find out that it bolts right up and if you drilled at 1/2 center like me you keep that stock oem gap maybe a bit tighter gap actually but it looks good , you can then install the grille by pushing the clips in and only bolting on the the top 4 10mm bolts once done youll find that the gap is nearly perfect if you drilled at center of the 1/2 mark , some drill under the 1/2 mark to get less gap and some enlongate the hole lower towards the original hole to adjust and have no gap , but i see that as rubbing issues with paint.
sorry for rambling on on the install , i will try to post all my pictures size will be limited and ill go back to proof read fix anything that i missed. Let me know waht you guys think or if you need help

On my 2015 Silverado Crew Cab 2WD, I currently have the RC 2.5 inch spacer leveling kit with all stock shocks. I am wanting to replace all 4 shocks with Bilstein 5100s. Does anyone have experience combining these shocks with the spacers from RC? I would also like a little more ground clearance. Nothing too crazy, just a little more aggressive look than the stock 2WD height with a leveling kit. Trying to decide if I take the spacers out and go with the RC 3.5 inch suspension lift with upper control arms, remove the spacers and go with Bilstein 5100 on the highest setting all around, or simply replace all shocks with 5100 and keep the spacers up front. Just trying to figure out what will get me the look I want and also be the most mechanically sound so I don't cause any weird issues with ball joints, etc. Any help would be awesome.

I'm looking to replace the driver's seat base (frame) in 3500HD WT with one that is height adjustable. The OE base is manually adjustable fore and aft, and for seat back inclination. My wife can't see over the long hood. I don't want to go with the riser rails available on Ebay as those would elevate me too high.
So basically I'm looking for someone that has a 3 way adjustable manual seatbase on their truck to contact me so I can get the right part, the first time. If your manual seat has fore and aft, seat back inclination, as well as vertical height, send me a PM so we can discuss off thread.
Thanks in advance.
I have a set of OEM front and rear all weather floor mats for sale. Part number: 84521602
photo is of the rear mats, can’t upload both photos because of the size but the front are in same condition. Lightly used, had them in my personal vehicle for about 6 months. New they’re $150, asking for $65+ Shipping. Will send with USPS.
Hi everyone, new to the forum here and haven't seem to be able to find an answer after searching.
Purchased a 2020 1500 AT4 last summer(love the truck), and recently added the Firestone Ride-Rite kit to the rear(kit #2609). I also ordered the 2" spacer kit as recommended (kit #2366).
I'm having a bit of a problem with the install and was wondering if anyone else has added rear air bags to their AT4, and did you end up using the spacer or were you fine without it?
Problem is the air bags are slightly misaligned, and appear "under-inflated" with the spacer in there even when I have 10-20psi in them(there is about 500lbs in/on the box via a canopy and a Decked box system installed in the bed; I'd rather not have to try and remove these unless I absolutely need to, to diagnose the problem).
I know in the instructions it says to have 5.5-6.5" of space between the upper and lower mounts. So my next plan is to jack up the back of the truck enough via the hitch receiver to recreate the correct factory fender gap front to back(should be roughly 1.5" from the factory with no load if I'm no mistaken?), and then measure the distance between the new mounts.
Thoughts and/or someone who has added rear airbags to their AT4? I'd assume the Trail Boss would be very similar?
