Level your LML or L5P Duramax to the perfect stance with the best kit on the market, the Cognito Elite Leveling Kit With Elka 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 Elka 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.

ELKA SERIES 2.5 RESERVOIR SHOCKS:
The Elka 2.5 Reservoir shock allows precise fine-tuning of the high-& low-speed compression damping so you can adapt the suspension for your specific driving style and terrain conditions without compromise. It also features an external reservoir with increased oil volume for cooler operating temperature, providing better performance and consistency.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.

Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.
