This high quality GM 3500HD lift kit offers an increased ride height for enthusiasts looking to run a 35in tall tire with enhanced offroad capabilities. The stance of the vehicle will become more level front to rear for an aggressive look. The factory GM upper control arms are replaced with Fabtech's heavy duty ball joint tubular arms. They are constructed with 1.50in OD DOM steel tubing and feature a high travel ball joint that is sizably larger than stock. This provides for increased strength both on and offroad. Fabtech sets the ball joint angle to allow for full travel without bind throughout the travel range. Fabtech's forged torsion bar keys replace the factory units and allow for additional ride height adjustment to work in conjunction with the new upper control arms. The rear receives 2in blocks and U-bolts to help level the stance of the vehicle. Fabtech offers their Stealth shocks with this suspension. They are a sealed monotube shock that has a Nitrocarb piston rod for corrosion resistance and resist rock chipping. They will provide a great highway ride with good offroad damping capacity. This 3.5in HD lift kit comes with high quality components that add strength and reliability to the vehicle while giving it a commanding presence. Tubular Steel Upper Control Arms. Additional 1 degree of caster built in. 1.5in OD x .120in wall DOM tubing. High travel oversized ball joint. 2.25in OD x .250in wall DOM bushing barrels. Heavy duty forged torsion bar keys.

Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.

Great sound mat for the price!

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.
