Lift your GM Silverado/Sierra 2500HD/3500 6.6L Duramax L5P 4WD with the Icon K78353 0-2" Stage 3 Suspension System from GAP. Tougher, stronger and more capable - That's the motto that General Motors used when debuting the all-new fleet of heavy-duty trucks in 2020. Icon Vehicle Dynamics stayed true to GM engineers' thought process with the development of our suspension systems for the 2020-UP GM HD 2500/3500 trucks. Using Icon's holistic engineering philosophy, our R&D team went above and beyond to develop several stages of complete suspension systems that provide varying levels of adjustability, capability, and overall vehicle performance. Icon's Stage 3 system is comprised of V.S. 2.5 Aluminum Series remote reservoir front and rear shocks featuring Icon's Compression Damping Control Valve (CDCV) for 10 settings of adjustability for any driving style or condition, and tubular Delta Joint upper control arms. 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. Remote reservoirs 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 billet upper control arms add strength, durability, additional caster, and camber adjustment, and when paired with extended travel shocks increases wheel travel 2" over the OEM configuration. 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.

Just what I needed
Color: Extra Large - 3Pcs
The bags were perfect medium size fit pair of men’s jeans and 3 shirts and a sweater. The straps were sturdy. It does comes with gift tissue in the package not enough for all bags but enough for at least 2 bags … if you’re like me and like to use 4-5 tissues per bag 😂

Good Size and Quality, But Strong Odor
Color: Extra Large - 3Pcs
These bags are a nice size and seem durable, especially for larger items. However, they arrived with a very strong odor that was noticeable as soon as I opened the package. I'm hoping the smell fades over time, but it was disappointing and worth mentioning. Overall, the bags are functional, but the odor keeps me from giving a higher rating.
