Lift your 2011-2019 GM Silverado/Sierra 2500HD/3500 6.6L Duramax LML/L5P 4WD properly with the Icon K78103 0-2" Stage 3 Suspension System from GAP. The 2011-2019 GM 2500HD/3500HD requires significant shock damping to comply with the massive spring rate of the factory torsion bar system. Icon Vehicle Dynamics has developed a range of suspension systems with optimized vehicle specific shock damping. These systems offer excellent on and off-road drivability. While driving the construction site or trails to your favorite dirt bike location, Icon wants you to get there in comfort just like your drive to work. The Stage 3 system is comprised of our V.S. 2.5 Aluminum Series front & rear reservoir shocks featuring Icon's Compression Damping Control Valve (CDCV) for 10 settings of adjustability for any driving style or condition. The Icon vehicle specific tuned 2.5" diameter shocks with CDCV are the key to attaining optimum ride quality and getting that desired comfort with the 3/4- & 1-ton working capability. Adjustable reservoir shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. Additionally, Icon upper control arms add strength, durability, and when paired with extended travel shocks increases wheel travel 2" over the OEM configuration.

Sound deading roller
These rollers are nice and heavy and work great for rolling out insulation in your vehicle sound deading

Sturdy
The ball bearings make them roll smooth. I've put plenty of pressure through them and no bending or breaking. The middle sized unit is probably the most useful. The small one has it's uses but can act like a pizza cutter and easily go through sound deadening mats. The large one has a little too much surface area to get a good crush on the mats.

Works great, good price
Makes installing sound deadening panels a breeze. A little elbow grease required but makes for perfect contact with the sheet metal and butyl.

Well Made Tools!
I have been installing Kilmat in my early 74 Datsun 260Z restoration and these tools are very nice for the price. I like them because they actually have ball bearings and move smoothly over the matting. The size selection is very handy as well and even has some nice finished wooden handles.
