So my dealer has done about 10 of these with the 2 inch rc level. Anyone else running that successfully? There doing it with 305/55/20 bfg k02’s. I want to fill my well out and get a little more lift up front but not totally eliminate the rake.

I see most of the people leveling their trucks but by raising the front end, has anyone leveled their truck but by lowering the rear? If so, any pics? I dont have an AT4 but I do have an Elevation model(and yes I'm thinking of lowering the back). Thnxs

Thought I’d offer my two cents on my mods. First I had a 2” front leveling kit by rough country placed. One gmc dealer refused to put it on. Second dealer no problem. Looks much better. Re aligned. Rides great. Then off for wheels/ tires. Have read 34” and even 35” tires are no problem. I placed nitto ridge grapplers 295/60/20. 33.94 x 11.7. Both fronts rubbed. Trimmed inside plastic flaps. Better, still some rubbing. So people claiming 34/35” clear, not on my truck. Wheels are Gear 20x9” with 18mm offset. Two custom wheel dealers called their reps and were sure they would clear calipers and not stick out past wheel wells much. They would not clear new larger front calipers. Had to add a 1/4” spacer on fronts to clear. Which means these wheels would need about 25mm offset to clear. Love my wheels but a lot of what I found on this forum and wheel/ tire shops I don’t believe to be accurate. I know the 2019 is new and we’re all learning. Just passing on my findings

Looks so good! Do you have a link to the wheels/ where did you get GMC centercaps for them? Thanks in advance. Also have you had any issues with the leveling kit?

Very close to what I did. Looks great.

Congrats Nik; looks great eh...haha. Fellow Canuck here. Haven’t seen too many long box models in the crew cabs. Love your wheel choice. Any clearance issues or rubbing?

Just browsing Motofab's site, and it appears they are now making a 1.5" lower mount level kit for the AT4 / Trail boss. Part number CH-15LM-TB.

Anyone aware of this, or possibly install it yet? It appears much easier than Rough Country's 1318 which requires a spring compressor.

It appears to be the 1.5" that the owners are already running here in the forum. I have mine sitting in the garage waiting to be installed but ordered before they released or re-labeled this particular AT4/TB lower strut spacer. My purchase order on ebay has a part number listed as "CH-15LM" only. Looking into the pictures they look indentical. Probably their way of telling people 1.5" is their recommendation for AT4/TB trucks.
