Lift your L5P Duramax to the perfect stance with the best kit on the market, the Cognito Elite Leveling Kit With King 2.5 Reservoir Shocks! This is a 100% complete kit with absolutely everything needed to properly level your truck. Most leveling kits available today are just simply a torsion key that you will adjust to obtain the desired height. Those type of kits will certainly lift your truck but overall driving characteristics will suffer and parts can fail prematurely leaving you stranded.

This kit includes the Cognito Ball Joint SM Series Upper Control Arm Kit, Torsion Bar Adjuster Keys, Cognito Pitman and Idler Arm Support Kit, front and rear King Series Reservoir shocks.

COGNITO BALL JOINT SM UPPER CONTROL ARMS:
These 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. Heavy duty ball joints are included as well as new crush sleeves and polyurethane bushings. The Cognito Ball Joint SM Series Upper Control Arms provide ample droop travel that is required for optimal ride quality and all suspension components to last and work properly.

COGNITO TORSION BAR KEYS:
These Cognito torsion keys are responsible for providing the lift for the front of your Duramax. These will allow you to level the front with the rear of the truck. Their forged construction makes them practically indestructible and they bolt in for easy installation.

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

KING 2.5 RESERVOIR SHOCKS:
King’s new line of Original equipment manufacturer, (OEM), shock upgrade kits provide a bolt on suspension system that elevates your on and off-road performance to unmatched levels. Each kit has been subjected to punishing real world testing to develop the optimal damping curves and spring rates for your vehicle. Built with the same quality of materials and precise tolerances found on Cognito's high-end race shocks these OEM upgrade kits enable you to experience the famous King ride quality on your daily driver or prerunner.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
