Built for the ReadyLift 66-3921 Suspension Leveling Kit for GM 1500 Trucks with 1.75 Inch Front Lift, this ReadyLift component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ReadyLift 66-3921 suspension leveling kit is designed specifically for 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, providing a reliable and safe way to achieve a 1.75-inch front lift. This kit is ideal for owners seeking to improve vehicle stance and accommodate larger tires without compromising factory suspension geometry. Crafted to deliver a level ride, it ensures enhanced vehicle appearance and functionality while maintaining ride quality and handling characteristics.
The kit features high-quality spacers made from durable materials that install in the front suspension, providing the desired lift while preserving factory control arm angles. Included are tubular upper control arms with corrected ball joint cup angles, heavy-duty replaceable ball joints, and terrain control technology (TCT) maintenance-free pivot bushings with side-biter washers. These components work together to improve alignment retention and longevity, especially when running larger tires.
Designed to fit specific factory models, the kit is compatible with trucks equipped with factory 2-inch lifts such as the AT4 and Trail Boss, but it does not fit Sierra AT4X or Silverado ZR2 editions. For the AT4, the maximum tire size is 275/60-20 with 20x9 wheels at 0 offset, while the Trail Boss can accommodate up to 295/65-20 tires with similar wheel specifications. The installation requires professional expertise and approximately 4 hours to complete, making it a suitable upgrade for serious truck enthusiasts seeking improved aesthetics and off-road capability.
Please note that this product contains chemicals known to cause reproductive harm under California Proposition 65 regulations. Proper installation is critical for safety and optimal performance, and users should ensure compliance with local regulations when installing and using this leveling kit.
