Has anyone installed a steering stabilizer on their 2020/2021 2500/3500 HD trucks yet? If so where did you get it and what brand?

Update to my post. The 37’s lasted 24 hours. I rubbed both pulling into and backing out of my office this morning on the hard plastic behind mud guard and on the felt liner up front. Went back this afternoon and swapped em for 295/65/20’s. Same tire smaller size. The 37’s looked bad ass but I’m off camber too much at the deer lease and on the beach to worry about hitting harder since it was already making contact just turning on level pavement. Here’s a pic of the 37’s (don’t mind me, sales guy at dealer requested it) I’ll get another tomorrow with the 35’s that went on tonight.

Well after standing and staring at both the 295/65 and the 37x12.50 at Discount tire for the better part of an hour (while they dismounted my factory tires), called in my son for a second opinion i opted for the 37’s. see how this goes lol. truck really looks great!!! detail scheduled for tomorrow, ill post more pics after.

Any pics Kylant? 3” front and 1” back i assume?

Got my 3” Cognito leveling kit going on this week and really want to go with Run the 37x12.50 Ridge Grapplers. it’s a Duramax. I do tow my 36’ work and play locally (usually within 100 miles) a few times a year. Trailer is heavy, roughly 15k loaded. 23’ boat when needed to come home for service few times a year also. wondering if I’ll be ok with the 37’s or if i should stick to 35’s. anyone else tow with 37’s on their truck?

Great review! We too bought the AT4 Yukon back in November, in the Cayenne Red tint coat. love the color. X2 on being able to select a ride height and LEAVE IT THERE! Much needed. I might add the lack of power adjustable petals. Do agree 100% with the engine having plenty of power and love the 10 speed. We did put Nitto Ridge Grapplers on ours right off, in the same factory size. Actually rides better now with less body roll.

Your truck looks great! mines the same except in the Brownstone metallic 3500. Did you have a factory block between the spring and perch that you removed and replaced with the 1.5” block? dammit...... I’m gunna have to spring for the 37’s. Truck looks perfect with them. happy with the Cognito kit so far?

Are you running 37’s also or 35’s?

My rear spring sits directly on the perch, no block in there currently. I do have a spacer between the main leaf pack and the overload leaf and spoke to Cognito and they confirmed the supplied ubolts will work with those. I have always admired the Cognito stuff and decided to spring for it on my new 2021 3500 AT4. I agree in your thought of if they thought it necessary then it would have been included. my kit should be here this next week. Leaning towards 37x12.50 Nitto Ridge Grapplers on the stock AT4 wheels.

Did you do any front diff drop at all with the Cognito kit up front? ive got the same kit on the way with a 1” block for the back but have concerns that thats are no provisions for the diff to drop included in the kit.
