Description

This robust kit strengthens the factory leaf spring suspension, providing significant improvements in stability and control. It is designed to reduce rear squat by up to 2 inches and mitigate issues like sway, bounce, and axle wrap, all while maintaining or even improving unloaded ride quality. Unlike air suspension systems, the RoadActive Suspension kit operates fully mechanically. It features a progressive tension design that automatically adapts to changing load conditions without the need for compressors, air lines, or ongoing maintenance. The kit comes pre-assembled for a straightforward installation process, typically taking around 3 hours with light to moderate mechanical skill. This Heavy Duty (HD) kit is compatible with trucks featuring a factory single leaf spring package and also with 2015-2018 models equipped with Magnaride suspension. However, it is important to note that this specific kit **does not fit 2022-2024 models with single leaf springs**. It is made in the USA and backed by a 5-year warranty.
