Manufacturer Description

Take the performance of your 2011-2019 GM HD truck to new levels with the ICON Vehicle Dynamics Delta Joint tubular upper control arm kit. All ICON tubular upper control arms are constructed from CNC bent 1026 DOM steel tubing and then powder coated to a semi-gloss black finish for maximum strength and corrosion resistance. ICON upper control arms are engineered with built-in caster correction for optimal alignment specifications and confidence inspiring handling. A main benefit of ICON upper control arms is the increased wheel travel (nearly 50%) when paired with our 2.0 or 2.5 series shock absorbers, this translates into superior performance and ride quality for your 2011-2019 GM HD. These upper control arms feature ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint. To ensure compatibility, ICON is no longer offering GM 2500HD/3500HD upper control arms as individual components. Upper control arms can only be purchased in unison with ICON shock absorbers as a complete system. The included ICON Vehicle Specific (V.S.) 2.5 Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all of ICON's Shock Absorbers, the V.S. 2.5 Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061-billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity.

Reduce sound vibrations in your car! Works great! This is not sound proofing, it is Sound Deadening
Size: 10 sqft, Size: 10 sqft
This Butyl rubber sound proofing kit includes nine 15 1/2" x 10" peel and stick panels. It really is a lot of coverage, but I still will need a second box to finish my car doors. The instructions are easy to follow and the only tools you need are scissors or a knife and a small roller, but you could get away with using a pan scraper to press the product down. You may need paper and a pen to make a template for certain areas, though. I used some cardboard from my recycle bin to cut template pieces for the hard to see areas inside my doors. This is fairly easy to install once you have it cut into pieces, just peel the backing off and stick it on. Be very careful to not let it stick to itself, as it will be nearly impossible to separate. This stuff is crazy sticky! No worries about it coming off once you've stuck it to your car. To add this to your car doors, you will have to remove the interior door panels, but there are lots of YouTube videos on how to do this on all sorts of cars. Note that is is sound deadening material - Not sound proofing! You do not need to cover 100% of the car with this. The material is designed to stop noise from resonating through metals, so even one piece of this on a large area of sheet metal will stop the sound vibrations quite a bit. I am covering about 80% of my car doors with it, then planning to put sound proofing on top of it. This sound deadening material needs to come in contact with the metal surfaces to stop the sound vibrations, so it would not be very helpful to put it on top of sound proofing material. Also note that the installation requires temperatures above 50° Fahrenheit. Since it is winter, I've warmed up my garage while working on this project. In low temps, the sticky stuff would probably have trouble adhering to cold metals. So far I have tested just having it on my front doors, but I already can hear the difference. This soundproofing definitely does minimize road noise and external sounds from getting inside your car. It also stops music vibrations, so my radio now sounds clearer than it did before. I don't plan to pull out my vehicle carpet to install on the floor, but I would imagine that if I did it would greatly reduce the road noise even more. Definitely five stars on this product!

Quality mats that provide noticeable noise suppression
Size: 10 sqft
I used these mats when I replaced the carpet in my Chevy Tahoe. Cutting the mats to size was easy enough with a utility knife and a straightedge. The adhesive backing stuck fairly well, but I used a roller to press the mats into place on the metal panels, which seemed to help them adhere a little better. Under the old carpet was the type of insulation you'd typically see under carpet in a typical home. It was worn, so I tossed it and installed the new carpet directly over these new mats. The before & after difference in noise was minimal, but noticable. But I only installed them on the floor - not in the doors, rear hatch area, firewall, or roof. So overalll, I'm pleased with these mats as they provided the noise suppression that I had expected.
