Go Ultra Low with a 4/6 Drop on Your 2019+ Silverado

Take your 2019–2025 Silverado or Sierra 1500 to the extreme with the MaxTrac KS331946S 4/6 drop kit. Built for trucks with cast steel control arms, this setup delivers a deep 4" front and 6" rear drop for a slammed, aggressive stance that stands out anywhere.

This kit is designed for those who want maximum drop without giving up control. Lowering your truck reduces center of gravity, improving handling, stability, and road performance, while still maintaining a smooth, controlled ride quality with matched shocks and struts.

Up front, drop spindles paired with lowering struts achieve the full 4-inch drop while maintaining proper suspension geometry. In the rear, a 6" flip kit with shackles and a C-notch provides the clearance needed for a deep drop, ensuring proper axle travel and suspension function.

Built from precision-engineered heavy-duty steel with a durable powder-coated finish, this kit is made for long-term durability. It’s a complete setup for serious builds, combining performance, strength, and aggressive styling.
