Overview

The Dirt King Prefab Bed Cage is a suspension kit designed for long-travel rear suspension performance on 2019-2025 Chevy Silverado and GMC Sierra 1500 models. It provides a strong foundation to properly support rear shocks and manage suspension loads, especially during demanding off-road use. The bed cage features a CAD-designed, boxed plate and tube construction, professionally MIG welded for durability and made in the USA.
Show original supplier description
Serious rear travel requires serious structure, and the Dirt King Prefab Bed Cage serves as the essential foundation for long-travel rear suspension systems. Its design prioritizes stability by mounting shocks outside the frame rails, unlike cantilever systems, and utilizes a near 1:1 motion ratio for effective dampening with vertically mounted shocks. The construction features robust boxed plate and tube elements, utilizing 2"x.120" tubing and 1/4", 3/16", and 1/8" plates. It offers specific recommendations for leaf packs (Deaver R81) and shock configurations, including a recommended 16" shock length (26" collapsed, 42" extended) with compatibility for 3.0" diameter shocks (2.5"-3.5" range) and bypass tubes on both the front and back. Installation requires welding four brackets to the frame, after which the entire kit bolts together. It is compatible with both leaf-over and leaf-under spring packs. An axle width requirement necessitates 1.5"-2" wheel spacers or a 1.5"-2" wider axle per side. Accessory mounting holes are integrated into the center section for accessories like dust lights and flag whips. This bed cage is specifically designed for the 2019-2025 model years of the Chevy Silverado 1500 and GMC Sierra 1500, in both 2WD and 4WD configurations. Please be aware that suspension modifications can alter vehicle dynamics, and prompt wheel alignment and ADAS recalibration are critical and the customer's responsibility.
