Clear up to a 38" tall tire and make your LML/L5P Duramax stand out from the rest with this 10" Performance Lift package from Cognito Motorsports. Cognito has bundled everything you need in this kit so there is no guesswork and you save with the bundled price.

COGNITO BALL JOINT SM SERIES UPPER CONTROL ARMS - The Cognito Ball Joint SM Series Upper Control Arms add style, function and performance to your vehicle by correcting the Ball Joint angle for lifted and leveled applications and improving the allowable droop travel for a better ride quality. The control arm kit features boxed sheet metal arms that are CNC robot welded and powder coated semi-gloss black. Ball joints are included as well as new crush sleeves and polyurethane bushings.

PITMAN AND IDLER ARM SUPPORT KIT - The Cognito Pitman and Idler Arm Support Kit: Pitman and Idler arms have been an inherent wear problem within the steering systems of Chevy and GMC trucks & SUVs for decades. The Cognito PISK (Pitman & Idler Arm Support Kit) replace the problem components that plague factory and aftermarket steering systems on several models and years of GM trucks & SUVs. These improvements are accomplished through application of Cognito's innovative, patented design, by providing additional support to the vehicle’s pitman and idler arms, which eliminate the forward and rearward movement of the center-link.

SWAY BAR - The Cognito HD front sway bar is designed to reduce body roll, so you have better vehicle control and greatly improves traction for safer driving. These HD Sway Bars are developed for this specific application. Measuring 1.5-Inch in diameter and made from heat treated and hot formed 4140 chromoly steel for extra strength and durability. Larger sway bar clamps and polyurethane bushings are included.

FINISH - All steel bracketry is finished in semi-gloss black powder coating.

SHOCKS - The Fox 2.0 Performance Series Remote Reservoir shocks contain the latest in shock technology to transform the performance of your truck. The Fox 2.0 Performance Series IFP front shocks are rust resistant and have a metal impact extruded aluminum body to increase cooling capacity. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving. They're easy to install and provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions.

REAR LIFT - The Deaver spring is a complete replacement of the OEM spring, and is arched for 4-Inch over stock rear lift height while maintaining an excellent ride quality via being made from high quality spring steel, a higher leaf count with thinner leaf material for a more compliant ride. The Cognito 3-inch Block and U-Bolt Kit includes 5-inch tall powder coated semi-gloss black steel blocks and heavy-duty zinc plated U-bolts.

Excellent Ergonomic Chair

I am incredibly impressed with this chair. The setup was a breeze and took me less than 20 minutes from start to finish. It is exceptionally comfortable, offering fantastic ergonomic support that keeps my back pain-free during long hours of sitting. The materials feel premium and highly durable. Plus, the included 5-year warranty is incredibly helpful and provides great peace of mind. I highly recommend it to anyone looking for a reliable workspace upgrade!

I am very happy with this office chair. It was easy to assemble, feels sturdy, and is very comfortable to sit in for long periods of time. The ergonomic design provides good back support, and the adjustable features make it easy to find the perfect position. The mesh back keeps me cool throughout the day, and the chair rolls smoothly. Overall, it offers great quality for the price and has made working at my desk much more comfortable. I would definitely recommend it to anyone looking for a reliable office chair. ⭐⭐⭐⭐⭐

Great Chair! Worth the Price!
Color: Sky Blue, Size: Pack of 1
LOVE my new desk chair! I got the Sky Blue which is a really pretty blue in person. I work from home in tech, and had been getting constant headaches no matter what position I was in. I finally decided to invest in a better desk chair, and I'm SO glad I did! It's much more supportive and comfortable. I really like that I can flip the arms up or down, and the height is easy to adjust. Also, because I can flip the arms up, I can keep the chair out of the way when I'm not working by putting it right up against the desk. Very much worth the price! Assembly was simply and quick. Not even 30 minutes. Also, when I had a question about the chair, their support team was quick to respond and very helpful. Highly recommend!

Great quality chair, regardless of price.
Color: Black+white, Size: Pack of 1, Color: Black+white, Size: Pack of 1
Great quality chair, regardless of the price, period. So well packaged that it took almost as long to unwrap as assemble. Assembly was easy (loved the Allen wrench with sturdy handle). I am 6'2" and the fit and height adjustments work well for my height. Comfort is personal, so I like the semi-firmness of the seat. While the chair is constructed of heavy gauge plastic the base is solid metal with enamel finish: I love the look. The arm rests line up perfectly to my computer keyboard. I expect many, many years of service.

Great Value for a Comfortable Home Office Chair
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I’ve been using this chair for a couple of days now, and honestly, it’s been a solid upgrade from my old one. I work from home most days, so comfort matters a lot—and this chair delivers better than I expected for the price. The first thing I noticed was the lumbar support. It’s actually adjustable and makes a noticeable difference, especially if you tend to sit for long stretches. My lower back used to get sore after a few hours, but that hasn’t really been an issue since switching to this chair. The mesh back is also a nice touch—it keeps things breathable, which I didn’t think I’d care about until I had it. Assembly was pretty straightforward. Took me maybe 20–25 minutes without any frustration. Everything lined up well, and the instructions were clear enough. In terms of comfort, the seat is firm but not hard. It doesn’t feel like one of those super plush chairs, but I actually prefer that because it feels more supportive over time. The reclining feature is smooth, and I like that you can lean back a bit when you need a break. Overall, I’d say this is a great value for a home office setup. If you want something ergonomic and comfortable without spending a fortune, this chair is definitely worth considering.
