The Icon K73064 1.5-3.5" Stage 4 Suspension System With Billet UCA from GAP are designed to dramatically increase the on and off-road ride quality in your 2019-2023 GM Silverado/Sierra 1500 2WD/4WD. Icon engineers' primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road. With wheel travel and ride quality in mind, Icon engineers researched each component of the GM platform's suspension and addressed any areas where performance could be extracted. The Stage 4 system provides a higher level of performance that will drastically improve overall on and off-road vehicle ride characteristics. The Icon 2.5 Series remote reservoir coilovers and 2.5 Series piggyback rear shocks in this system provide exceptional cooling properties, with the coilovers utilizing Icon-engineered Eibach coil springs for superior vehicle "feel" throughout the range of travel. Remote reservoirs front and rear ensure optimum performance by increasing the duration of consistent damping, keeping the shocks at a cooler operating temperature during extended offroad use. These 2.5 Series remote reservoir CDCV coilovers are also height adjustable from 1.5-3.5" allowing the use of larger, more aggressive wheel and tire combinations when desired. The Icon Vehicle Dynamics 2019-2023 GM Silverado/Sierra 1500 Stage 4 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as optimum performance in the dirt.

Decent 3oz measurer
Color: Black, Color: Black
I like it, it works. However it is a bit heavy on the handle side. You think somebody like maestri house would get it correct. Could have used heavier metal on the measuring cup. Anyways I keep it it's nice.
