Paul Horton's Welder Series Triangulated Rear Four Link Kit; 3-Inch Axle Brackets (Universal; Some Adaptation May Be Required)

GM Triangulated Rear 4-Link Suspension KitDesigned with the tried-and-true triangulated 4-link configuration used by GM for decades, this rear suspension kit provides enhanced stability and eliminates the need for a Panhard bar. Its adaptable design accommodates various frame widths, making it a versatile choice for custom builds and restorations.High-Quality Construction and DesignBars: Constructed from 1″ heavy-wall seamless tubing, each bar is tapped at one end with a 3/4-16 thread and precision-notched for the urethane bushing tube on the other. The upper bars measure approximately 18" center-to-center, while the lower bars span about 25" center-to-center. This setup ensures strong support and effective articulation.Frame Brackets: CNC-formed from 3/16" pickled & oiled mild steel, the upper frame brackets are robust and can be trimmed for a perfect fit across a range of frame widths. The lower frame brackets feature a 3/16" thick section for frame welding, providing extra durability where it’s needed most.Axle Brackets and Tabs: Made from 3/16" pickled & oiled mild steel, the axle brackets and upper axle tabs are engineered to withstand the demands of high-performance applications.Adjustable Coil-Over MountingThis kit offers three mounting positions for coil-overs on the axle brackets, allowing for flexible ride height adjustment and suspension tuning. For those preferring to install coil-overs later, consider our adjustable ride height setup tool, which temporarily replaces coil-overs during the build phase. This tool preserves coil-over integrity and provides clearance checks for components like the exhaust and driveshaft through suspension travel.Premium Energy Suspension BushingsAll bracketry is matched to the outer diameter of Energy Suspension urethane bushings (1-3/4" wide, 1-5/8" OD), which deliver excellent vibration dampening and add a clean, streamlined appearance upon assembly. The kit includes 3/4-16 threaded adjusters to fine-tune suspension alignment for a tailored fit to your build’s specifications.Kit Specifications:Model: 318500 (available in both welded and ready-to-weld)Bushings: 1-3/4" wide, 1-5/8" OD Energy Suspension urethane bushingsAdjusters: 3/4-16 threadedSee related parts for 2-5/8” OD axle tube adapters.Complete installation instructions are included to support a smooth, straightforward installation, making this kit a strong, customizable solution for GM triangulated rear 4-link setups.
